  • Chaos Cosmos model materials and UVW Channel node

    Sometimes Chaos Cosmos model has UVW Channel node and UVW Channel value -1 which shows wrong UVW channel, when changing value to 1 then it works.
    For example Barrel Cactus 001 model.
    Left cactus has original -1 value and right has 1 value and it seems correct one.

    Good catch, thanks for the report. It seems that for this asset in particular, the correct value should be 1 (positive 1).
    This affects other Cosmos assets too and we'll look into it

      And when Chaos Cosmos proxies are scaled 1/100 from the original size (in Blender proxy object scale is 0.01), then V-Ray Mtl Bump Amount value is 100 times too big, so its bad looking. Scaling proxy object back to scale 1 corrects bump but object is 100 times bigger

      Edit: so Bump Amount value should be divided by 100 in Blender.
