Is there a way to achieve higher detail with textures similarly to the way IdTech 7 uses geometry decals? And no I don’t want to use nanite because that would make the assets huge and static.
Would overlapping UV coordinates be comparable to this? Obviously this wouldn’t be a useful technique to use if you are baking texture maps. Are there other reasons why you would want to avoid overlapping UV maps? What about multiple UV sets? Are there any other alternatives?
You can just place decals…
The idea is that you have 1 decal texture (normal map) always loaded in providing different normal offset for different decals you place around.
Niagagara wouldn’t really help or speed things up here.
Aside from decals, there is no cheaper alternative to them.
You can just use better models and rely on Nanite (or so epic wants you to believe)…
yup, atlases with like a bajillion decals are awesome, as well as trim sheets, especially when they’re combined. It allows no only to up the detail level, but to make it ridiculously fast.
Take for example Ghostrunner 1/2 - they’ve put A TON of decals on everywhere and it helped with visual fidelity a lot. And with the first game it was in the UE4, so no nanite at all
If you’re a Blender user there’s a god-like addon which makes the process of making decals really fast and easy
including export to UE:
