Hi… in all the time that I was making games (model and texturing), I always joined all static objects into one mesh, for instance, a chair (wood) with a tablecloth (fabric), different textures inside one mesh, so in Unity in Inspector Panel i got one mesh with multiple materials (each material equivalent to one texture)…
In various of my cases, i don´t use Atlas because I preffer to repeat the texture many times (tile the texture into the face), because that… i have one texture per method:
I have a big mesh named “House” (table, chairs, tv, library, tablecloth, windows, and many many things. all statics).
For that, i´m using many textures as "tableWood.jpg, chairWood.jpg, libraryWood.jpg, tableCloth.jpg, windowFrame.jpg…etc).
When return to Unity, house mesh appears successfully. and when i click on it, inspector panel shows me all the textures with their respective materials…
does this method is troubled to build a scene?
what method do you actually using?, separate meshes per material, atlas, combine meshes using the same type of material (sort as reflective, diffuse, normalmapped, transparent)…
Thanks.
