Hello. Took the day off and wanted to make some progress on those dunes again. I started by taking a step back and thinking again about what I wanted to achieve here and it’s somewhere between those two references.
Then spent most of the afternoon on Substance Designer. I managed to make some improvements that I’m happy with like that “Y branching” of the main dune shape and more convincing secondary waves. I’m quite happy with you it feels in Unreal Engine so I might move on for now and switch to the next step.
I didn’t want to rely on tiling textures purely for those secondary shapes and I’m glad they read well enough with just the landscape mesh. So next step might be trying to texture that sand dune in Unreal Engine?
