    Rendering Time

    I personally don't think this has anything to do with GPU vs CPU vs whatever settings you have in your V-ray dialogue. I have had this problem in the past and my solution is something that I used to do all the time when using previous unstable releases (ie. before 6.7). I once again keep a notebook next to my computer and whenever the program starts to act a little funny (you know what I mean) I write down exactly what I was working on at the time and what tools I was using. Recently I was working on a project and I introduced a new texture map a client sent me. Within an hour my program was bogging down and acting strange. I went back and looked at the map and it was a huge png file. I resized the image and resaved it and the system cleared right up. I have had similar experiences with the terrain tool, Reshape tool, Nurbs, Blend tools and lots of others. It is surprising how easy it is to corrupt your model but still have it render out (but very slowly). So I guess the best advice I have for your situation is to think back to what you were working on that might have caused some corruption of your model. If you can't think of anything then slowly go through your materials one by one. If they check out then start using the object doctor on some of your more complex geometry or things you might have worked on a lot. This is not exactly a perfect solution but often it is the only option. As for the Mac vs PC thing mentioned above I would not hold my breath for any real upgrades from Apple to their pro line of computers. They are now a phone company and have been for years. Why sell a few thousand pro computers when you can sell 300 million phones that need to be replaced every two years.

    3Dconnexion Space Mouse drifting.

    Out of curiosity do you like using the Space Mouse and do you find it to be more accurate than the basic Logitec M510? What are the advantages that it has? Do you use it in conjunction with the CAD mouse they sell? I have had a lot of issues lately with my mouse when I switched to the M705 which displayed some really bizarre behavior.

    form•Z Anniversary | Thank You

    Happy birthday as well! At the risk of sounding like an old man I started using Form.z around 1991 when I was working at the largest architecture firm in the US. I believe my machine was a Mac IIcx which was barely able to render out a simple image in shaded view. I used it mainly for doing perspective layouts for my watercolor illustrations. It wasn't until about 1997 that I presented my first digital illustration for a client. Fast forward to today where my watch has 1000 times the computing power of my IIcx and I haven't done a watercolor in 10 years. While I have tried almost every other modeling software out there I still can't help but come back to Form.z. Simply the best modeler out there to date. Really looking forward to seeing what they come up with in the future releases.

    VRAY - Huge Material Problem!

    The native format for Form.z materials for V-ray is VRMAT. However, I have been able to download VISMAT materials from various sites and then open them in the material editor. Then I save them as VRMAT so that I can use them. I have not been able to use any other formats.

    Portal Light

    Try turning off all other lights and adjust the intensity up to 100. Then go to the camera settings and see if you can get it to show up in the render. If not then try simple portal light to see the effect. It should be much stronger. I also give my portal light a texture map that matches the exterior scene which helps realism.

    Request for V-Ray Tutorial or Example Scene

    I probably have done more interiors than most on this so I will chime in here. There is really no set way to do an interior as the lighting will be different depending on the situation. Unlike exteriors that rely on a simple sun position or a dome light. However, there is a process that I use that I will share. First off set your exterior sun to the desired position for interior shadows. Go to the suns override settings and make the size of it 5 so that the shadows are softer. Make sure your glass is not casting or receiving shadows. Now place a light plane that is the size of your window just outside your glass and make it a portal light. I often give this light a texture map (hdri) so that it adds atmosphere to the image. Set the intensity to about 50. Parameters: invisible and does not affect reflections. Place a rectangular box area light in the middle of the room and make sure it does not touch anything. Set it to about 30 and make sure that under Parameters it is invisible and does not affect reflections. This is true for any other interior lights you might add. Then I go to my camera settings and adjust the exposure to get it close. It does not need to be exact since you can always adjust exposure during the render process. I will then turn on AO, adjust the shading rate up, set my render elements and adjust everything else in the V-ray settings while I am there. Once I get the lighting about right I can then add specific cone, spot or line lights depending upon the architecture. These don't seem to add much to the overall exposure but they help to add realism to the scene. One thing that I would like to comment on in your scenes is the lack of gloss on many of your materials. All materials have a certain amount of gloss to them. For some reason the default for V-ray is set to a black color and a value of 1. For me I start with a white color. For dull materials like rough plaster I will set the gloss to 0.2 and for high gloss I will set it to 0.85. While we are on the subject of materials I also find it very useful to assign a Material ID color to my most important materials. If you then enable Material ID in your render elements you can adjust color and isolate the materials very easily post process. This saves a lot of time later. It also allows me to place my window reflections perfectly on my exterior scenes since I have my glass isolated. Finally, for true realism I also use the Glare effect in the render window and sometimes I will even use the Bloom tab. Some clients hate these and some love them so use them cautiously. Hope this helps. As always there are many ways to set up a scene and this is just my down and dirty approach for a starting point.

    Example Images

    One difference I see in your retail display is the lack of illumination on the etched lines in the glass. First off how did you do the etched lines and do you think there is a way to illuminate them similar to the finished product? Glass is always a bugger to deal with and Vray glass is no exception.

    When doing interiors I usually have to do two different lighting schemes. One which is warm and inviting and has a certain amount of atmosphere to it. This is for my portfolio. The other is the one the client requests which is cool and every material needs to be perfectly accurate to the material board or sample. Interior designers are strange that way and not a whole lot of fun to work for. Material accuracy can be very time consuming. As for the clothing I think you could experiment with V-ray displacement to see if you can get it to loosen up a bit. I use that tool a lot now and find it to be much faster and easier than straight modeling.

    How do you rotate perpendicular to surface?

    I personally use the Define Reference Plane. This is because I build things progressively and I often need to align things to the rotated object. Define the plane, name it and save it.

    From Foem Z to Unreal engine

    I use Max but I also own a program called UV Layout by Headus. I found it pretty easy to use. I think it was $200.

    V-Ray vrscene/vrproxy export Settings

    I agree 100%. As I mentioned above the interface is awkward and very slow when importing a scene file but in the end it saves me a ton of time not having the sheer mass of geometry in the model which would kill my system pretty fast. For decades I had only used 2D trees and plants in my final images and now with V-ray I am able to use 3D assets in the program that I never could use before. In a perfect world programs like X-frog, Plant Factory and Onyx tree might take notice and work on an interface that could allow us to integrate their plant assets directly into Form.z and Vray. For now I just create those plants I need and go through the tedious process of exporting them from a tree builder program, import into Form.z, re texture map and then save it out as a scene file. Once I get a large enough library things should get a lot faster.

    V-Ray vrscene/vrproxy export Settings

    That is a question that has been asked many times now. I don't imagine we will get an answer until right before it is released. Getting back to V-ray proxy objects I have gone back again to examine this and I still stand by my assumption that this feature is broken. If I take a bush and group it together then select the group and hit export v-ray proxy nothing happens. Nothing. I should get a dialogue giving me an option to save my proxy object somewhere just like it does for Scene files. I don't really care as long as I have some way of saving my complex geometry in a manner that frees up the program. So scene files is where its at.

    Simple modeling... stuck on basics!

    One of the great strengths of Form.z is that there are usually many different ways to create the same geometry. The forums are full of variations on techniques to do things and everyone has their preferred method. In this case I would just create the wall and then go to the front view in elevation. Turn on grid snap and set it to one inch increments. Then go to the rectangle tool, select the 2D surface option and make sure that Insert is selected. Draw a 16x9 rectangle on the surface of the wall where you want it. You can now use the transform tool to offset the rectangle in by 1".

    Can't load textures

    Corrupted image files are a constant problem in both Form.z and Vray. Always check the extension and when in doubt do a save as on the image file. This is a problem that has been growing slowly for a while now. Glad to hear you got it worked out.

    Can't load textures

    Andrew Take a look at your underlay file and make sure it is either a standard JPEG or a Tiff. And then just for fun do a search to make sure your Video Card drivers are up to date.

    V-Ray vrscene/vrproxy export Settings

    Flosimo Since Tech is absent in the forums I will try to explain where we are at with this. First off what you are trying to do is correct in order to bring complex geometry in to Form.z without it bogging down. That said vray proxy is broken and should not be used. According to Tech Chaos group included it in the package because it was hard to take it out but they advise not to use it. I tried at first and immediately gave up. They advise to use V-ray scene files instead because they include more information and are more stable. Stable being a relative term. In order to make a scene file you open your geometry in a separate model and then open the palette called "v-ray". The last two icons in that palette are place Vray scene and export vray scene. When exporting you need to identify the path where you want it stored and check "pack" to include all texture maps. Be aware that if there is a vray sun in your scene it will be included as well. When importing your scene file you will need to make sure you uncheck "import lights" or you will have a second sun in your scene that can not be edited. If you forget to uncheck that box then right click on the object and go to its parameters tab. Click on Edit and then turn off the sun light. When placing your scene files back into a project be very patient. The placement seems to take a lot of computing power and it is often slow and arbitrary in terms of where the geometry shows up. I will often throw a few scene files in and them place them accurately later. Changing the preview from normal to bounding box doesn't help the speed. Once you are done placing your scene files take a close look at the whole model. I often find that I have some extra arbitrary scene files placed in random locations far from where they are supposed to be. These I just delete. All in all it is nice to have this tool since the Components feature of Form.z has been broken for a very long time. I have used this to bring in trees and plants that would have killed Form.z instantly. It is still a work in progress but hopefully getting improved upon.

    Example Images

    I agree with you that the lights need to be set by temp. I absolutely loved the way Maxwell handled lights but the time cost of using that program was just too high. I miss multilight a lot too but I need to make a living.

    Very nice job. The lighting is very realistic and inviting. If I may make a couple of suggestions I would personally change the aspect ratio to show a little less ceiling and a bit more floor. Then add a spot light fixture for the light on the painting and perhaps water in the tub. The cabinetry is quite a dark void and it gets a bit lost without some definition. These are just personal comments. Technically the image is great. Keep up the good work. Are you using IES lights for your spot? Here is a bath that Justin and I did this week just for fun. Playing around with the fur tool and displacements.

    V-ray troubleshooting

    To all of you out there that are using V-ray now and might be having some issues I have a generic solution to a lot of your troubles. As I get more heavily into materials and lighting I have noticed some really strange and unpredictable behavior. Things like the material editor really slowing down and material previews not showing. Then last week my ability to create and edit V-ray cone lights suddenly vanished. SOLUTION: Throw your Autdessys Preference folder in the trash can. When the program is relaunched the folder will be re created. To find this folder it is in an unusual place (at least for me) Go to : C_Users_(Your Computer Name)_AppData_Roaming_autodessys. Happy hunting. Andrew PS- One other useful tip is to never waste your time with the V-ray Proxy objects. I have been informed that this is an old tool that needed to be included for some reason. It does not work. You should create V-ray scene files if you want to bring in high poly models and keep your resources optimized. It works great for trees, bushes and people. When creating scene files you will find that the program creates a sun light with the scene model. When you import the scene you will need to disable the sun or you will end up with multiple suns in your project. To do this you need to to to the objects V-ray parameters and edit the sun out. Just an FYI

    Form Z error ID: 128: -35

    I might be able to help. What are you trying to do when this error occurs?

    Sharp edges/creases in sub-d models?

    Personally I would forego Sub D and go straight to Nurbs modeling. In the past when modeling furniture and cars I would create profiles and then start joining them with the Nurbs Loft, Nurbs Boundery and then Nurbs extend, blend etc. It has proven to be more reliable and predictable when accuracy is important. To get sharper edges you just use Tight Lofting. Just my two cents.

    VRAY - Huge Material Problem!

    This is still a work in progress application. For whatever reason I sometimes have the same problem. (v-ray textures not showing up in shaded view). The other issue is textures not previewing in my material palette which makes it especially difficult to find a material if you have dozens of them in your project. (Tech can you hear us?). If you have been poking around for solutions in the forum you will see that I have posted a go to fix for all things V-ray related several times. Throw out your preference folder and let the program rebuild it upon restart. Somehow this debugs the material issues for a little while. See if this helps.

    "Show Controls" not working?

    Your pref folder if you don't know is located at C- Users-Computer Name-App Data-Roaming-Autodessys

    "Show Controls" not working?

    Another simpler solution is to throw out your preference folder. I have had to do that quite a lot in the past year but the latest version I have seems to be much more stable. Version 10213.
