I'm quite a noob with blender so it probably has something to do with something I haven't ticked, so I'll give as much information as possible.
So I've built a very basic building to later export it into a game, I have made the UV and Unwrapped it, but when I'm trying to draw a texture into it by using Tex Draw, the texture doesn't actually get applied:
I don't know if it has something to do with the shading or what to be honest, here comes my shading settings too:
Here are the settings for the brush too
If there's anything I am missing please do let me know and I'll answer as soon as possible, I just really want to start with the texturing as I've been working hard (as hard as you can when you are a beginner really) in this model, thanks :D
