Make a new material and use textures and normal maps to get the details you want
what is the pixel size of the textures you are using?
Hey guys , I want to have cracks and dirt in my asphalt . But i have a very big scene (a city basically) which all of the asphalts are just 1 big plane in all of the city . doing it manually by decals is not a big problem for me but i wonder if its very expensive . any idea ?
For a texture that is tiled like 10000 times , it would tile and copy the details 10000 time , right ? correct me if im wrong
its a 2K asphalt Textyre
You have to change your approach for this. Hand placing that much decals over an entire city is just crazy work and not efficient. You should look into making something less time consuming, yes you will get repetition in the textures but that is to be expected in a way for such a big scene, and if you spend all your time placing decals all over the city and your level gets corrupted all that work is lost and you can start over.
I don’t think it will copy the details 1000 times, when Unreal is loading a model whit a texture, it will only load it and that is it. a normal map wil give the illusion of a big polygon model, you can use that to make a wall look like it is made of briks. and 2K txtures is a good size.
When you build the game, it will compress all the fiels. And if you use LOD, then your game should smooth and fast.
