Try reverting to default settings and test. (See bottom left icon for default settings)

Try to create a new generic material, and then use this image in the Opacity row. The image should be transparent. Or in the Diffuse row of that image, try to check/uncheck "diffuse map alpha as transparency", below advanced options. Thanks.

When this happens to me I just save and close SketchUp. Then I open it again. Try also to click on that three dots on the top right corner and change the material view. Could it be just a graphic's problem? Thanks.

hi every one, I have also problem with rendering my file. It is big file, a tower, I tried to delete objects as much as I can but not much helpful. It so weird sometimes rendering but mostly caused my PC hang and even cannot shut down. mostly I have to press and hold power button to restart computer. I tried copy it and paste in new sketch up file, purge, explode those groups with many components or subgroups but still the same. Since it is for on going project, seriously I need ur help.

Hello, Archimonia, on this SITE, some VRay4SU tutorials. There is one on glass settings. Enjoy !

me the same. still searching for saturation option in vray 3. color bleed is everywhere when i dont have the option. ps: i dont want to edit the option in material option. its to much.

@manny2000 said: Hello there. I’m having the same issue 1 as you. I Can’t figure out what the problem is. Have tried with large renders and on a test, simple render with a couple of materials. It renders fine in CPU only mode, but as soon as I activate the GPU acceleration the finished render is totally different, much darker and some of the materials qualities change totally …very strange indeed. I have tested it on different computers and the same thing happens. I have searched google and I can’t find anything about this issue until I read your post. Would appreciate any ideas to fix this extremely annoying problem. Thanks in advance. I’m using Vray 3.4 on sketchup pro 2017 Windows 8.1, Xenon cpu and asus 1060 gpu i to have same problem

Anyone please help

@eidam655 said: ...write a converter for the old materials It may be worth asking this request on the Chaos Group forums. Maybe they can figure out something that can write the old materials with the reflection and refraction layers into one BRDF layer. That would in fact be quite useful. @unknownuser said: Thanks for the answer. You're welcome!

Ok, I have fresh news I start to the beginning and I test all my texture to find the ONE that do bug everything and is...... a carpet texture make with VRAY FUR. But I don't know why my render stop at 66% with the texture (it's a png that insert with BITMAP on material menu), maybe my setups are not good ? Thanks

@solo said: At the time it cost $3600 but that same setup now is around $2800. Though in no way cheap, that's actually less than I would have thought. Thanks.

In this second set of images I am using the select and apply drop down in V Ray to copying the material from the right to the pillow on the left. I don’t know why size/scale changed differently. I checked and changed both the SketchUp and V Ray U/V sizes and they both change sizes up or down accordingly. With this being curve surfaces I do not have access to the texture drop down menu.

Are you using the latest version V Ray 3.6? ifso your answer is can be found here: https://www.youtube.com/watch?v=HZ_FeuG9WSE you need to go to your settings tab and pick the GPU button then click on the 3 dots and look to see if your graphic card is showing up there , you can then pick its on or off. when on a check will show up next to name.

[image: LkSj2pE.jpg] Is it better? I'm afraid that I can't do better, larger picture. I mean I can but it will take ages.. So.. what happened? As I said I'm new in sketchup and v-ray but it never happened to me before. Sofa, ceiling, walls, floor...

You are right, that was the problem... thank a lot for your quick and useful reply!!

The sharp edges are really hurting you here. Adding a chamfer to the edges of your geometry would really help things out....get rid of those sharp edges and help pick up some corner highlights. Also some dirt maps added to your textures so things don't look too 'perfect'. Both will help you render not look so 'computery'. Also looks like you have a light ray coming in from the top left, though the shadows on the house say the sun is above to the right.

So, I found how to turn on subpixel clamp, but when I do, the render gets super noisy, and the denoiser doesn't seem to do much of anything. Turn off the clamp, and less noisy render, and denoiser makes it even nicer. Anyone know what's up? Thanks, Dave

for my tub i created a toon effect, it just looks better this way but on my photo there is no toon effect.

What you are seeing on the pillar is in fact a texture that is scaled down very tiny and repeating. You need to increase the size of the texture to something more realistic.
