* Speed up Vray Materials previews
* Improved Displacement calculation
* Updated GI presets
* Improved Light Mesh code with better precisions and support for instancing and mograph cloning
* Improved Sun light control in Physical sky, you can now use only the physical sky illumination without a physical sun. Good for overcast skies or for separating sky and sun to have independent control over both
* Area light now can have bitmap and shader textures now (also rectangular area lights, good to built natural studio lights, light boxes etc)
* Lights now can use shaders instead of light color. You need texture scalings rather big (ca 100-500x)
* Normal export rewritten, also added extra support for objects with negative flipped axis by vray core.(Mirrored objects with setting axis to -1 will not result on artefacts anymore, no need to use the axis reset tool anymore)
* Shadow color now can be changed in physical Sun light (please note that only black is physical correct though)
* Shadows now can be textured by use of procedual shaders. You need texture scalings rather big (ca 100-500x)
* All C4D Lights can have now physical emitter values, they use a approximations as if they would be very small area emitters (watt, lumen, etc), for 100% precise Photometric Lights use only Area light though, as in reality are only Area light.
* Material Weight maps now can be used to limit or multilayer Displacement

Video tutorials collections to introduce the user in Vrayforc4d world, a general exploration of render settings and very powerful vray techniques.
