hi. since using the latest 1.8 version i would like to give some new ideas. the custom material type has such option like invisible for raytracing. we need this option also in cloth or custom alpha. for example we have curtain with alpha texture but we need the lighting to be traced through the curtain and not throught the alpha texture. i mean the curtain must be also invisible for raytracing to get full light from exterior.
another idea is to add more texture manipulation tools like texture brightness, contrast, saturation, gamma etc. this will make textures more tweakable for faster workflow avoiding using ps or other image editors.
