Hi,
as i need to change the texture of each side of a cube seperately at realtime, i thought about one group/texture per side to use ent_setskin.

But it seems that too many objects(200) with multiple textures have impact on FPS.

SO as the mesh shape is pretty simple, maybe using one skin for all cube sides and bliting the required tile when needed?

Or maybe using one texture, which includes all available tiles and shift the uv setting?

edit:
the manual says that vec_foruv is replaced by ent_getvertex/ent_setvertex.

But for this function, it is (indirectly) written that it does not support UV modification o.O
(as most properties of the contact struct are not described in the "used" part of the manualpage.

I would create for each cube two dummy skins and assign to 3 quads skin1 and to 3 other quads skin2. Then, I would create two materials for each entity (!), store the pointers in two skills (for later use) and assign these two materials via ent_mtlset to entSkin1 and entSkin2. Since each material can hold up to 4 BMAP* pointers which are accessible through mtlSkin1 ... mtlSkin4 in a shader, you can store 3 BMAP*s in Material 1 and 3 BMAP*s in Material 2 to cover all sides of your cube. Then, you write 2 shaders for the two segments of the cube (with 3 quads each), which map the mtlSkin1...mtlSkin3 to the sides of the cube, by evaluating the normals and blending accordingly (one pass; 3 texture fetches per pixel) or by writing 3 passes (one pass for each side, thus only one texture fetch per pixel). Thats it.

okay, but this doesnt work for my dk dig terrain demo.
As my 2x2 tile objects require more skins(4), by using this technique. So i end up with multiple skins aswell.

Mh, i see, it was a VERY bad idea to use one group for each cube size. FPS went down the road o.o.

But the shader method becomes a bit complicated for 2x2 cube meshes, i think

edit: but maybe a shader is the only way to skin a mesh without splitting it into to many groups :|

Yes, don't work with groups. Each group means one more draw call afaik and that is not that good.

Yup, all meshes contain one group now, but splitted tiles for setting up the UV individually.

i created one material, which is assigned to each block, and renders the textures.
i will try how fast it works when i setup the UV for each tile at creation.
