Hello,
I've released the new Experimental v0.1.99-beta3 for Windows 32/64bit and Linux 32/64bit with the new Extended Texture Mapping system, among other fixes. Please see:
http://www.yafaray.org/community/forum/viewtopic.php?f=12&t=5094The new texture mappings in addition to the existing ones are:
Diffuse Reflection Amount in Shiny Diffuse, Glossy and Coated Glossy materials
Sigma factor for Oren Nayar in Shiny Diffuse, Glossy and Coated Glossy materials
Filter color in Glass and Rough Glass.
IOR refractive factor in Glass and Rough Glass. The texture amounts are added to the IOR of the material.
IOR refractive factor for the Fresnel in Shiny Diffuse and Coated Glossy materials.
Roughness factor in Rough Glass material.
Exponent factor in Glossy and Coated Glossy materials
Mirror amount in Coated Glossy materials.
Mirror Color in Coated Glossy Materials
I also added a (non-texture) mirror amount slider in the Coated Glossy material
Along with the builds, I included some example scenes and images showing the new system. These are some examples. I hope you like the new version
