    Turquoise artifacts

    I am in desperate need of some help and hope that someone out there has seen this issue. I have a huge project that is due Monday and the program just started glitching out on me. Everything was rendering just fine in test images and then suddenly my whole render image went turquoise blue. I restarted the program and the color came back to normal but now many of my materials have weird turquoise blue artifacts. I restarted my computer several times and each time the image is different and corrupted. It is worth noting that the only thing I changed in my model was the addition of two people that are scene files. They do not have lights associated with them. Anyone else ever have this issue? Is there anyone other than Justin and I even using V-ray? Thanks for any help you can offer AW

    DWG import colours script (LAB?)

    You should have gotten a warning when you imported the DWG a second time. A pop up window should tell you that the imported file has the same material names as the current project. It should ask you if you want to use the materials in the current project or the ones from your clipboard. You would just use the ones from your current project. Are you not getting that warning? AW

    test render window?

    Sure. I assume you are trying to use V-ray to render a region. In that case you hit the render button and the v-ray render window opens automatically and starts rendering. Just stop the render and then at the top menu bar there is another little Teapot with a red little icon next to it. That is the render region button. click on it and then draw a rectangle around the area you want rendered.

    window insertion upside down

    Easy Bottom of modeling tool palette just above the trash can icon is the edit axis icon. I think that is what you are looking for.

    surface from segments

    Josephus I am not sure what you are trying to do but closed 2d geometry is by definition a surface. Could you post a screen shot or the actual model piece to examine?

    Object pallette - active object (FZ Jr)

    I agree with you completely on this one. It would be nice if the objects palette was more useful but I have never found a way to find my objects easily in there. As a result I always have the objects palette turned off.

    Example Images

    Here is another example of exterior and interior lighting. The final render at 4500 pxl wide took about 14min. I am very impressed with the speed and quality of Vray these days but there are still a few bugs to work out. I also wish they would fix this forum so that my images can be viewed at full res.

    Disabling shift key/"Insert" toggle

    Not that I am aware of. Looks like it is baked into the program since it is not one of the listed key shortcuts.

    snap - project on reference plane

    Yes Right click on the snap to point (or any other) option and a menu pops up for snap options. There you will find "project on reference plane".

    The sign in link above is still broken so everyone please remember that to sign in you need to right click on the link and select Open In New Window. That said here are a few new images for review. Still a work in progress but every week it is getting better. Still having trouble with portal lights and dome lights in association with other lights in the scenes.

    Interior lighting settings

    I have been messing around with trying to optimize the lighting for an interior scene and thought I would share what I have found to serve as a guide. Hopefully this will help others with the constant trial and error. The trick is to balance the portal lights so that they affect the scene while adding light in specific areas. My scene is a condo in Grand Cayman with big windows behind the camera and a hallway with a glass door at the other end. I created a plane light for each window and placed it inside the room just inside the glass. Make them portal lights in the parameters and set them to 100 intensity. Be sure to turn off Affect Reflection if you don't want them to reflect off the shiny surfaces in your room. It is not necessary to turn on Invisible as that doesn't seem to affect the plane since they are portals and that is redundant. Now comes the interesting part. You could just adjust the camera to adapt to the portal lights but my clients often want more control over how the areas of the room are illuminated. So I found the best method is to use mesh lights to flood certain areas of the room with additional light. Mesh lights are still a work in progress at this point so be careful. I create a rectangular box about 24 inches high that is about 50% of the size of the area I want to illuminate. Place it a little lower than mid way between the floor and ceiling and make sure it doesn't touch anything. If you get your mesh light too close to the ceiling you will get strange light patterns from the box shape. Make them invisible and set their intensity to 25%. IMPORTANT: Do not rotate these mesh lights! Currently that corrupts them. I also ran into issues when scaling their size so create a new light for each area. Hopefully the next release will fix a few of these quirks since Tech is aware of them. Now you can go to your camera settings. For this room and my conditions I set my ISO to 300, aperture of 11 and speed at 120. This is close to real world photography settings so if you are familiar with cameras that helps. Other things of interest: If you have very reflective surfaces (in my case high gloss cabinets) then you need to place a plane with the reflection texture map behind the camera. Turn off shadow casting and receiving for the plane and set it to Emissive in V-ray materials. My scene was the sky and ocean behind me which added color to the reflective cabinets and atmosphere to the room. These are apparent in the Raw Reflection channel which I overlay in PS using the soft light layer mode. I use the Reflection Channel over that and set it to Screen mode. Adjust the levels as needed. Always include a Material ID output channel in your render so that you can adjust all your materials later. Now there has been a lot written about Noise in the reflection channel in all V-ray platforms and now I will address it for Form.z. As the distance from the camera increased in my scene the noise got much worse. My past solution was to Despeckle my Raw Reflection Channel in PS but that often led to a muted and blurry reflection. Tech informed me that I need to add more light to that area to supply more rays or I needed to render out at a much higher resolution (6000 px wide). Adding light might not be what you want and huge renders take time. There is another option which is under V-ray settings- Raytrace- Optimization - Shading rate. Default is 8 and you can set that to 16 to 32 which slowed the render but cleaned up the noise quite a bit. While you are in the settings you can also solve another issue if you have multiple transparent surfaces overlapping each other ( a glass bowl on a glass table in front of a window for instance). Your alpha channel will not render correctly unless you increase your Max Trace Depth. Default is 5 but you might need to increase it to 6 to 8. There are a lot of other little tweaks at our disposal but this seems to be a good starting point for my images. I would be very interested to see how others are setting up their lighting for interiors and how it affects quality and render times. AW PS. I tried to post an image but this forum is still broken.

    open / add project broken in last build?

    I just tested this on my system and it worked as expected. I go to "open" a project and then click "add to project" to add what I want. All materials and views came in fine. Windows 7 Nvidea gtx1080 running FMZ 8.6 with V-ray.

    Material ID

    I completely agree. The material ID channel is critical to post production work no matter what your field is. Every client likes to tweak the final materials and re rendering is a complete waste of time. Form.z must implement a material color ID channel into the Form.z translated materials without having to translate it into a V-ray material first. I will see what they say.

    Material ID

    Finally. After searching for another 45 minutes I found it. For those out there that like to adjust their materials post production here it is: Go to the stand alone material editor Advanced-Options-Color-ID color This is an important feature that most people will find useful. It should be noted that within Form.z there is no way that I have found to set the material ID. You must save it as a V-ray material first and then use the Editor.
