I thought it would be cool to share OSL shaders that folks have been writing for Vray. So in the spirit of the thread of the same name for a certain other software that uses OSL, I thought I’d start one here for Vray. I’ll kick it off by sharing an OSL fabric shader I wrote: fabric.osl This is an …

@mayanic : Your problem is that you’re using the wrong node type - VRayPluginNodeTex:TexOSL instead of VRayTexOSL. If you create the correct node it will work as expected. After you change the output as mentioned by others.

Did you work out why this was happening? Same thing here, can’t find any info on it…

Are you both using the installer or are you using V-Ray from a network location? Do you have a variable like VRAY_OSL_PATH_MAYA2014_x64 set? It should point to the folder that contains oslutil.h and stdosl.h files.

haha - that was easy :slight_smile: THANKS one more question - i don’t get n1, n2 and n3 values from websites like refractive index? so one has to guess what green and blue values to choose?

It should reference the website refractiveindex.com , but the process for colored metals like gold is quite complex, so I made a little tutorial about it: http://docs.sharktacos.com/misc.php?action=help&hid=66 If you scroll down to the section Artist Friendly Metal reflections (texture) you’ll get …

The OSL’s seem to transfer with DR on to nodes as an asset, but blackout during rendering, have anyone tried using those shaders with DR on?
