Pyrex Posted August 3, 2011 Share Posted August 3, 2011 I've bee unable to get transparent textures w/ alpha channels to render in vray at all. They appear fine and correct in the material editor, however they are invisible/ random visual errors when rendered. I've tried standard materials, and vray materials to no avail. It's just a simple diffuse texture for a tree, with a separate opacity map for the transparency. Anyone care to help and explain what I'm doing wrong?

BexFX Posted August 3, 2011 Share Posted August 3, 2011 Hi, Can you upload an image of what the visual errors are like? Also a screengrab of what your settings are in the material editor? Bex Link to comment Share on other sites More sharing options...

Bex Well, unfortunately I'm away from my system right now. Basically It's a simple texture with a tree branch diffuse, with a inverted opacity map. With the standard renderer, they appear transparent and correct in the viewport, when I switch to vray it has a white background with all of the leaves and renders them invisible. I must be doing it wrong. Link to comment Share on other sites More sharing options...
dimosbarbos Posted August 3, 2011 Share Posted August 3, 2011 Hi, Would be preferable if you upload the geometry. I'm sure I can help. Dima. Link to comment Share on other sites More sharing options...

Scott Schroeder Posted August 8, 2011 Share Posted August 8, 2011 Dumb suggestion, but make sure you are using the opacity slot and not the refraction slot. If you are using refraction and have it set to 1.0, that will/can cause problems. It also helps speed up rendering when you disable image filtering on your opacity map. It'll take less time for Vray to calculate things. Link to comment Share on other sites More sharing options...
Pyrex Posted August 13, 2011 Author Share Posted August 13, 2011 Sorry for the slow reply. I've been busy. Well, I'm back to revisiting this problem. I can't show you a render because there's nothing to show. I downloaded the Forest lite plugin from Itoo software. The trees look great in the viewport, and they render fine outside of vray, in Vray they are invisible, can't even see them. Does anyone have a good vray setting file I could just pickup and test? It must be something in my render settings. Link to comment Share on other sites More sharing options...
Pyrex Posted August 13, 2011 Author Share Posted August 13, 2011 Here are some screenshots to take a peak at: *EDIT: Apparently this forum auto-scales, so right click view image to see the full size. You can see the trees in the view port of each render, and they don't even appear in the render. I did not include the material view because it's a plugin and it's being loaded separate from the material editor - I tried making my own, standard material, vray material, and I switched to the plugin because I know it works in vray from other people. Any ideas? Link to comment Share on other sites More sharing options...
Jon Berntsen Posted August 13, 2011 Share Posted August 13, 2011 Pyrex, what kind of plugin are you using? Most of these plugins have setting describing a max numbes of instances being rendered, and exceeding that limit makes it ignore. Link to comment Share on other sites More sharing options...
Pyrex Posted August 13, 2011 Author Share Posted August 13, 2011 I am using Itoo Forest... but it has no limit to my knowledge, you can have thousands of trees... and the ones I was testing are only 2d sprites. Link to comment Share on other sites More sharing options...
Jon Berntsen Posted August 14, 2011 Share Posted August 14, 2011 I'm also using Forest Pack and did encounter the same problems as you before. Check the Display tab in the Forest instance and change the max instances below the Render section to something like 50000000, and the trees will be rendered. Hope that will work for you.
