I have noticed that Dimension doesn't clear any deleted assets. When I deleted my 3D model including custom Substance textures closed the program and opened it back up, it still weighed 4.66GB.

Is the handling of custom Substance textures being worked on? At the moment there is no way to save neither the Substance material, nor it's parameters so they can be reused. I am forced to import the same material for every components separately which is nonsense. Thanks!
