I’ve just discovered a problem with CoronaBitmap parameters. I usually use Bezier Float controller to connect the U and V tiling values for different maps in the same material. It works fine with 3ds max default bitmap node, but with CoronaBitmap the tilingU and tilingV parameters sets the tiling mode, not the size. Hope you can fix it in a future update (did not checked if there are more badly connected parameters in any Corona specific maps).
Checked this in 3ds max, we do not have this param (Corona 9 hotfix 1). Don’t know if it fixed in hotfix 2, but U and V tiling should not a linked uvwScale value. According to my screenshot, there is no suitable param, and still, I guess the tilingU and tilingV should be the thing I need, but it may not connected (in the coronaBitmap code) to the proper value.
