    Mesh Light Question

    I always wanted to ask that question as well. The weird point in space away from the mesh always throws me off when I select the mesh and then want to switch to another view to move it somewhere. The screen centers to that point first rather than the object. As for the controller I just rarely use it for transformations. For what its worth I create light bulbs by giving them an emissive material. Then I create either point or cone lights for the power which don't have those weird points out in space. I still find that emissive materials in Vray just don't work as well as they did in Maxwell. But again, there is always a work around. Which is something I have gotten used to saying a lot over the years.

    Model no responding to Reshape

    I often have the same problem. I find it ironic that the very thing I hate about Sketchup models has been introduced into Form.z with the Reshape Tool. Namely that it allows for the creation of non planar geometry and missing geometry. I am not sure why all of a sudden the reshape tool no longer works but it is often a case of my working quickly on a model and then something random happens. If you explore the attributes of the object in question you might find that it is suddenly an open shape or non planar. Thankfully there are a lot of work arounds. The other thing I hate about Sketchup as well is the fact that people constantly build geometry from faces of existing geometry, which is also a Reshape issue. Once everything is attached to each other it makes it very difficult to both texture map and to modify. Things get messy in a hurry.

    Lamp Shade

    If you watch this video you will understand what I am after and why I need it:

    Lamp Shade

    I am in need of a quick tutorial on how to create a glowing lamp shade. In all the videos I have seen they start with 2 Sided Material as a base. However, I can not find that option anywhere in the Vray editor or in the materials library. Anyone have a solution that they have found that works well? Here is one tutorial http://www.cgdigest.com/creating-a-lamp-shade-material-in-vray/ Thanks for your help

    Okay folks. We are getting close to the release date and we all want to see what people have been creating with V-ray. I thought perhaps I would get the ball rolling. Post away.

    Extensions suddenly not loading

    Joe When you say you trashed the Autodessys folder do you mean the preference folder? That is what I occasionally trash to fix things. AW
  7. While I have not used Renderzone now for years since Maxwell and Vray came out I still remember the good old solution that I used to use. This is really quite simple. Create a solid 1/2" thick plane. Use material Glass Accurate in the reflections channel. Within the Reflection channel set reflection to 90%. Set the transparency to 0. Leave the other settings alone. Then below the Reflection channel you have your transparency channel. Open that and set it to your desired amount. I use 85% for most windows. Make sure you to to your glass objects and turn off shadow casting and shadow receiving. Now go to your Display Options palette and under Renderzone options go to Scene and change your background tab to Alpha Channel. Now export out your renderzone image as a TIFF file. Open it in Photoshop and under your Channels tab you will see your alpha channel. Does that do what you want it to? Andrew PS. For those of you who might say that I am creating a double transparency object I say so what. It has never given me any issues over 30 years.

    Lamp Shade

    I really hope that the next release has the 2 sided material option that all other Vray users have access to. For those who are not familiar with it this allows you to have an outer material and an inner material that are different on the same plane. So the inside of a lamp shade can be an emissive material and the outside can be a fabric. Another example is a leaf with sunlight shining through it. Some day.

    Shaded Render not working with Imported File

    Make sure that your video card driver is up to date. Check to see that your attributed texture maps are all jpegs and of a reasonable size. I had issues with some 30mb texture maps that came with a model and choked my system.

    I can answer that for you. When a 3 d person is absolutely necessary I go to either 3D Sky or TurboSquid. The Sky models are a lot less expensive. https://3dsky.org/3dmodels/category/zhvie_sushestva?page=3 Really pay attention to the export options on their models to make sure that they are compatible. I usually use OBJ if available. Andrew

    VRay fur - save to preset option

    I agree 100% and I will talk to Tech about this. When things get complicated in my models I tend to take screen shots of my settings once I get them to work properly. One annoying feature of the fur tool is that if you get it just right and then open the project the next day your Blade Count defaults back to Zero. No fur. I then go back into the dreaded Attributes Palette and scroll down to Vray Fur Attributes to re enter the blade count. So my solution is to always set my fur to Per Area, make the area the same size for all future fur materials and then always use the same blade count so that I remember. For me that means 6 sq inches and a blade count of 50 which gets me grass, fur and shag carpet as a starting point.

    Portal Light

    There are many things that only work in CPU for me. I gave up on GPU rendering almost immediately. Fortunately, my twin Xeon 10 core processors are quite adequate for quick renderings.

    Lamp Shade

    I will answer my own question here. After many hours of searching for a solution that mimics all the tutorials out there I have gotten word from Tech that this feature does not exist in the current release of Vray for Form.z. They plan on including it in the upcoming V9 release now that they have become aware of it. So if you need a glowing lamp shade or a back light object with semi opacity you are out of luck for now. Photoshop to the rescue again! AW

    Strange Artefacts with Vray 3.6.6.1

    I have yet to use the GPU or Hybrid render engines. There are just way too many issues associated with it and I actually find it to be quite a bit slower. CPU is plenty fast and it provides a consistent output that I can always count on. One thing that GPU does not do is allow for a Material ID channel which I use every day.

    undos are still broken

    Happens to me randomly about once or twice a week. All of a sudden the undo's don't work. Close the program and restart solves it every time. Until it happens again. This is something that has been around my office for many years now and I just learn to live with it like so many other quirks. If you are having a consistent issue with this and a restart does not clear it up then I would suggest trashing your preference folder before I bothered with a program reinstall. Just my two cents.

    Another option to create bump normal maps is to go Filter>Nvidea Tools>Normal Maps Filter. Works like a charm.

    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.

    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.
