New Sigma texture mapping proposal

Post Sat Apr 11, 2015 5:20 am

Hello,

Due to the request in http://yafaray.org/node/559 I have made some changes to add Sigma texture mapping to Shiny Diffuse materials that use Oren Nayar, for more realistic diffuse materials.

I've sent Pull requests for both Blender-Exporter and Core with the changes:
https://github.com/YafaRay/Blender-Exporter/pull/21
https://github.com/YafaRay/Core/pull/76

I've attached an example .blend file and some example images. I hope you find this useful.

Hello,

I've made an experimental build for Blender 2.74 / Windows 7/8.1 64bits including this fix. Please see:

Please test it and let us know if it works for you.
