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 …

Nice! Can I add this to the repository of OSL shaders here? [image] OSL Shaders Best regards, Vlado

Ok, I will just add some tooltips for the parameters. Best regards, Vlado

Thanks for the shader :slight_smile:

Here I’ve added tooltips to some parameters and renamed others to be perhaps a bit clearer: [image] Chaos Docs @Derek : do you want me to add some additional information to the page (like a link to your website)? Best regards, Vlado

Hello, I tried to use the Frabic file from OSLShaders in the V-Ray for Maya 2015 SP6, Win 8.1 (version 3.05.04, revision 25954 from Jun 29 2015) But once I load the file I get fatal error. Is there any other step that I did not understand? Thanks for OSL and attention!

There is a bug in the OSL library that manifests itself on Windows 8.1; we’ve fixed this and submitted a patch, but for the moment you will need a nightly build to get it working. You can email support@chaosgroup.com to get that. Best regards, Vlado

Looks great. It makes sense to rename things more explicitly as you have (Spec_glossiness instead of Glossiness etc). Hopefully once widgets are implemented in OSL one can use the “page” widget to organize the sliders the way a VrayMtl is (diffuse section, spec section, and so on). The pic would l…

Let me also mention that the bump map behavior is not the same as a VrayMtl. It looks to me like it is off by a factor of around 100, so to get the same bump as a vrayMtl with a bump value of 1.0 the OSL needs a bump value of 100. A quick and dirty workaround is just to add a multiplication like thi…

Here’s another OSL shader I thought was cool. It was originally posted in the Max forums here: http://forums.chaosgroup.com/showthread.php?81605-Complex-fresnel-using-VRayOSLtex&highlight=gold+osl . It uses the complex fresnel equation for metals, but to make it more artist friendly it remaps the re…
