Trying to update to PBR terrain (without side projection) this is what I have so far. With fifteen layers for each material, I guess I was hoping for an improvement. This is what my old level looked like with the same materials. My next map will be a desert.
It was a leftover from Torque 3D but you can still see the option in Cliff, maybe others that have not been updated. It's turned off here but I like the way it 'projects' rather than stretches terrain, esp. on steep slopes. Well you can see the ugliness on my example. It's probably not compatible with PBR but I felt the need share my grief for it's passing.
