Hello !! I am trying out a 3D coat tutorial, but i cant seem to get my layers to "clip" like the tutorial video. In the first screenshot is where a vox tree layer was dragged into another so that you can make transform tool changes simultaneously. However when i do the same , my layers just keep falling down on each other. Like in the 2nd and 3rd screencaps. I tried making a folder layer also like the example video, but needless to say my layers dont get grouped in effortlessly, and just fall back down or above the layer draged too.. X( HELP !
