My landscape material currently has 12 textures (six Diffuse & Normal only) on seven layers. I will add two to four more layers. Obviously, I need to add more textures.
Yet, I’ve hit the upper limit of material textures (12 of the 16), and need more. So, either I resort to atlases or I use the Shared:Wrap option for each texture in the material.
My question is: What are the pros and cons of these approaches (12 texture slots vs. Shared:wrap)?
