hi.
i am building up a game right now with an underwater scene. therefore i need to have some rocks. on youtube i found the following video: - YouTube.
i would like to make the rocks looking quite similar to these, but i just do not know how to make a material to let the rock-lowpolymesh look like this. could anybody please tell me how to achieve it? thanks a lot.
The easy way is to import Unity’s package with rocks. Don’t remember exactly which one it is, check out the asset store, free assets, model->nature(?).
The hard way, create the low poly in your 3D app, save it, tessel it, create the holes made from water erosion. Finaly, bake the normal, height and ao map, use them for a bump specular material. Or paralax (I’ve never tried that one).
