After being momentarily confused by your title I figured you'd be talking about displacement or normal maps and oh look you're making a displacement map XD That's a pretty cool railway tile, are you going to start putting scenes together after making all these textures? :D
Hi, thanks for your feedback!
Yes I will, I am currently doing a pretty big project so i'll try today to free some time to make another post with a guide and put some stuff in a scene.
I might upload a game file that could be downloaded and played, not something too fancy, just a demo.
Stay tuned!
