Hello modders Got into terrain building and have the need for new buildings (we dont need another greek island do we?) and have moved into addon making.Ive become proficient enough with blender and OB to be able to make some structures and get them working in game with uv mapped textures but have found that i should be using multi.rvmats for quality texturing.Im a bit lost with this.Ive looked at mondkalbs tut and looked through sample models and the rest. Heres how i believe it works? I uv unwrap my model in blender ,export this to gimp ,paint say the exterior walls red,interior black.These colours then get linked to _co.paa textures via text in a multi.vmat file.The coloured uv map is referenced in the rvmat as _mask.paa Is that part correct? .....Is the one uv map made in blender enough or do in eed to make 2 and combine them in o2 like in mondkalbs tut, or is this outdated? ..Ive noticed that in the tut he uses what looks like a standard textured uv map tagged as _mc aswell,and from what i can gather is the base texture and the mask is like an overlay?Is that correct? But if i look into A3 models and there textures ,they use _mlod as a textured uv map and _mc is like a grayscale or some shit...more questions to come!!!
