Its a very big problem right now for me to not be able to use OSL textures as displacement. Why are they not usable? Surely they can be evaluated as easily as color?
The procedurals that are included with vray are not very comprehensive at all and to not have the option to write a quick OSL shader is a very large handicap.
What I was needing was a cellular texture with a time control. This would be easy to write as OSL if only it worked for displacement.
But, that uvwgen input of the OSL shader isn’t doing anything, no matter if I plug in a world, object, or UV named texture nodes, the result is always the same. I tried with the noise maps here: OSL Shaders
I tried an allagator noise and it didn’t displace. That + the manual saying that displacement doesnt work let me to think that it wasn’t working.
it might be because I had some uv modifications.
There was an issue exporting OSL uvwgen which is fixed in the nightly, however this particular osl shader is not using any UV at all. Could you pls try some other which actually uses UV?
