As a Roblox developer, it is currently too hard to adequately manipulate multiple textures on the same object face. When applying multiple textures to a face of a part, there is no way to determine which texture will be placed on top of the other. This is particularly challenging when using one texture as a background layer and then applying another texture with transparent attributes to add further detail to it.
An example of this issue would be creating a custom brick wall texture with a texture of grass lining the bottom of the part. There is no way to manipulate either the properties or the texture manually to guarantee that the textures will be seen in the order of grass on top of the wall as opposed to the wall covering up the grass. Furthermore, even if a result is successfully achieved where the grass is lying over the wall texture, it is possible that when studio loads again the images will switch places and the wall will cover up the grass.
If this issue is addressed, it would improve my development experience because I could more reliably manipulate texture behavior on different parts while also insuring standardization in texture behavior - rather than having a texture behave one way in Studio and then behave/display differently when Studio is reloaded.
Thank you for your consideration!
