Well then luck once played on my side.
When it comes to software, odds are that something that should work just doesn't, but that something works that actually shouldn't, that's new.

I like the skin settings in MED that allows me to give an object a colour without the need of using a texture. I assume that it takes less resources than a texture, so since my object doesn't need any texture I'd really like to find a solution that doesn't mean I have to give every part a texture.

Could this be turned into a feature?
Since it worked miraculously...

But if there's no such solution, can I give the non-transparent parts a texture with only an alpha channel, so that no texture is actually visible and the defined colours are used?
