So, I am doing a bit of research into 3d game graphics and models, I am pretty much a beginner when it comes to game graphics.
Looking at the images bellow, it looks to me that these bricks and stone walls are meshes, not flat planes with a bump texture on them. If I am correct, is this considered a good way to model stuff in Unity, or should a stay with bump maps? I know that normal maps wont work, since they wont work from “extreme” angels. it will of course then be a lot more feasible to build the game for mobile if I decide to at some point.
And, if i model my stuff in say sketchup, if I were to create such a brickwall, the best way to do it would be to create a component/group (prefab) of 1x1meter etc. and then copy this 1x1 component until i got my brickwall. Will Unity see that these are the exact same object, so that I’ll get better performace in game?
The grim rock article seems like a good way to do it. I plan on using ready made textures to save time. And I think i will apply the materials in sketchup then model variations, like the cracked floor, with the texture applied.
This one is a lowish poly mesh with a rock/stone texture applied to it. Most of the details and shadows on the rock texture, might be hand painted onto the rock texture. And it’s possible, that a bump or normal map, might be on it too. Probably, to give it a fine hint of detail, and bumpiness. I have seen rocks like that, in Dead or Alive 2 on the dreamcast, moreso, in the Snowy stage with the stone heads, where you normally fight Ayane, if you’re playing Kasumi in story mode. This one might work well on mobile easily, provided that the polycount is not too high.
This one is a bit more difficult to figure out. I might need more camera angles of that structure, to figure it out. But it’s possible, that the brick wall is a semi low to mid poly count mesh, geniusly modelled in a way, to accomodate the brick texture. And the details and shadows, are hand painted onto the brown clayish brick texture.
But I do agree, with the parallex mapping technique thing, that mgear mentioned above. It’s possible that that could have been used.
