bump & transparency

[linus]

ok guys, a new problem (?) for you:

i'm tryng to render a net, so i've made a painted surface in SU and created my linked material. Then i try to give transparency & bump to this surface, but:

- i must give transparency after each render (yes, i click on "apply" before launch the render)
- i use the same texture for the both effect (a b/w jpeg) but i see in the material preview just tue bump effect: no transparency!
- last but not least: i don't see any effect (bump & transp) in the final render!

what did i wrong?

here is a screenshot with the bump & transp values (you can see the material preview)

Check out tutorial C to explain how to handle decals in our current material system. It is specific to V-Ray for Rhino, but the material editor stuff is the same.

tnks joeb! nice tutorial... i've read it and followed the instructions, but maybe i've found a "bug" (?)
I've made the set up of the diffuse and transparent channel (then click "apply").
When i close the material editor (or launch the render) i can't see any map. So i re-enter the material editor but the material that i've edited is still without the diffuse and transparent channel ! ! !

That drive me crazy! Is it just my beta 3? Or is it me...


EDIT: i've tryed with a "new vray material" and now the net (map+transparency) works. So the problem was just with a SU linked material...

Yeah - you can't modify the read-only diffuse layer of a linked material. That layer is made based on the SketchUp material you are linking to. So perhaps you should just be making a regular VRayMtl
