Hey I want to make detailed procedural terrain but would like to use the GPU to create most of the detail.
If I make a low res version of the heightmap + normals on the CPU and set a material for it to use could I then use a vertex shader to add detail and then apply the material shader on the updated terrain? This would require some engine changes which is fine, but if anyone could point me in the right direction it would be much appreciated!
Physics is something I’ll have to deal with later, but I’m wholly unconcerned with it atm.
Thanks for the help, sorry if this is a stupid question!
