Hi! I love the alpha! And it is nice you put it here semi-free, when I am in a Blue Cube, it seems there are two textures at the same place, so it is kinda a texture bug. Other than that, the Cube of Natali had the texture patters different. I want to make a SVG version of the overlay, 

I wish I could make a different texture for the doors, but on the other hand I have almost no experience with Unreal, but I am experienced in Photoshop. But if I want to make an SVG version of this tile above, I have to make it in illustrator.

Hi. I'm glad what You want to help with some textures, and i think panel texture should have two layers - lower paintable white panel texture, and upper texture with schemes. And door is a 3d model, it just have seamless metal textures, it not so easy to texture it.
