Suggestion: custom transparent textures/surface type choice in build mode

[Harmonica]

Currently if you import a texture with transparency it kinda works, but it seems like it's inverted. for example transparent areas are black but opaque areas or partially transparent areas are actually transparent. You can see the default wall texture underneath so it shows that it can work okay, just need options to eg invert the transparent areas and also to choose the materials that show underneath (and/or the wall surface itself which would be cool to allow painted designs).

I wanted to customise glass with a etched pattern but this is not currently possible because we aren't able to apply the texture to glass :/ Likewise cannot seem to apply textures to a particular surface types - I don't know why but I think it just gets a tile pattern underneath always? (mostly visible if you make it glossy).
