Yes, I couldn’t stand those FUGLY stretching on my rock corners, so I went ahead and made good, straight UV’s for my rocks and seamlessly tiled my texture on them. No more stretching :))
Also, nice update on your work. Is the rocky canyon sculpted from the landscape or are they modular rocks put together seamlessly (how?) to form the canyon for the player to move in? Also that reddish illumination you’re getting in your rocks’ shadows makes them look good, are you using colored GI post processing?
