Post by: koubankeo on 2020-10-28, 12:57:05

UVW randomizer shader doesn't work with corona bitmap shader when cubic projection is used?

Thanks

Works fine here (e.g. with a default cube). Would need more info - would need to see your UVWRandomizer settings (remember "Randomize each tile" needs to be checked, and Number of Tiles generally needs to be greater than 1, and you need to have some variation in min/max of things like U or V offsets, scales, rotations, etc.). Also would need to know what you mean by "Cubic", are you adjusting the UV mapping in any way in C4D? Cheers!

A standard C4D bitmap works fine for me also, when using a Corona bitmap the texture loads as black. This was previously reported  :/
