Change Log

VRAYforC4D Version 1.25

Enhancement

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

New Features

Added newest Vray core 1.90.03
Added true dispersion in Refraction Layer
Added option to set exit colors on reflection channels
Added option to set exit colors on refraction channel
Added option to show AA samples, this is good to canalize and improve an AA solutions
Added GI option to limit ray distance, can give speedups (speed up strongly depends on scene)
Added material option to limit reflection by a certain depth (in real world units), with fading control
Added option in overwrite material to set a per object based reflection environment (similar to the global reflection environment)
Added material option to force materials/objects to be calculated by brute force, even though irradiance map is used in vray gi options. Enables use of brute force per material or objects that use that material (good for detailed interesting for animations too)
Added translucency texture in BDRF SSS under Refraction channel of the Vray Materials (and much better and faster Volume Fog and SSS effects) as per user request.
Added Compensate exposure option in Luminosity Layer, it will make an auto exposure of the luminance color/texture, a multiplier of 1 will then be always for any physical camera exposure if this option is checked. Useful for easy and fast use of luminance textures/effects.
Added option to set custom multipliers for diffuse light emissision (default = 1x)
Added option to set custom multiplier for specular light contributions (independent to light intensity, default =1x)
Added new LC option to set ray depth og light cache calculation. (default =100)
Added option to use environment fog for BRDF SSS calculation
Added vray dirt material into diffuse and luminance channel, good for dirt effects and for fast AO.
Added option to mix inverted vray dirt material to achieve multilayer effect of surface dirt
Added ability to set c4d lights color, even if a vray tag was added (color will be transferred to the vray tag in that case)
Added emit on Back Side parameter in Luminance layer of the Vray Materials
Added new emitter parameter in Volume refraction
Added option to auto connect AA threshold to DMC threshold (recommended to use in most situations)
Added option to enable/disable shadow casting of the atmosphere in physical sky
Added show calculation phase for caustics
Added Vray Fur Tag, with procedual fur/grass/short hair/carpets solution, it generates special dynamic geometry on the fly during rendering for anything where you need fast and simple hairs or fibers. Detailed controls by textures or shaders
Added vray Volume environment fog, in Vray environment settings. Can be used with any object as „gizmo“, density, color scattering, falloff can be controlled with native c4d 3d shaders (noises). very detailed control by textures and shaders, optimized for GI use. Good to make fog, ground fog, clouds, mist, smoke and other volumetric effects. Note that GI is also volumetric in this release, light truly scatters through the atmosphere volume (no fake scattering)
