Large concrete areas

David1983

hello folks, after watching the very nice the divison trailer and gameplay i noticed something that is going around in my head for quit a while.

Every here and there in games i see large areas of concrete or filed or whatever for a material. And i'm wondering how the artist for this scene is able to avoid ugly repeating of an material. I know there are vertex painting techniques etc... but if i take a look in my provided image, i see only concrte and water pudles but the concrete looks like very different in all the aresas especially the cracks... So is this bascially one material with a ton of crack decals or how is this handeld ?

Vertex Paint between three materials and add a few decals is a good start.

And to pimp it up vertex paint some puddles.

Good luck and enjoy.

hey, thanks for the clips! but I'm alreday familliar with vertex painting
My question is more about the general procedure of creating this large areas. especially the variation in cracks.

The cracks are most likely decals as they should blend easily with the concrete with a good alpha map. Puddles are probably decals with some kind of displacement map. There isn't really much else to say. Get a few different concrete textures, blend them, add decals etc. It looks so good because these guys have access to probably one of the best engines out there, and they are really good artists obviously.

Another option to counteract obvious repetition is to blend a macro mask with your roughness channel for more subtle surface variation across larger areas. For instance those subtle brighter cracks near the car door could be just that.
