It seems like half the time when I want to post something here, I can’t. But then everyone with a UE4 question seems to be able to post down here.
I posted something I thought would be useful to the UE3/UDK community a few days ago. But because of this forum bug I couldn’t post it down here where all of us will see it. When you get a chance you should take a look at How to: Get object rotation in material, recolor the normal map based on rotation, for UDK world-space tiling--with correct normals even if you rotate the mesh This is something that I do for reusing big meshes at different scales to fill in my maps. And I think it’s also just an interesting look at how normal maps work and how you can manipulate them.
