as Uly said: 2 planes (quads) intersecting each other, so it forms a + if you look at it from above, (= 2x2 = 4 tris) then 2 quads for the axe so you can mirror that. (4 + 4 = 8 ;))
put 16 256 textures into one 1024, you will need two 1024 textures to cover all the tiles.. that way you will have 2 materials, 2 draw calls instead of 27 like you have now..
a non-power of 2 texture will sort of work on the DS, sort of, but its UVs will more than likely be all screwed up. Doesn't matter about the hardware though, no professional game coder (or artist come to that) will suffer a texture that isn't power of 2
just trying something out, its some interchangable outfits more through texture than mesh, making use of alphas still a work in progress but heres my current progress consists of: 1 head mesh (44 tris) 2 vest meshes (272 tris per mesh) 2 pants meshes (134 tris per mesh) a generated character is currently 450 tris in total…
