Very informative response, thank you! I'll definitely try to combine everything into a single mesh to reduce draw calls then. One question though, I have my eyes rigged up via constraints already, should I simply combine it to the main mesh now? Are the teeth/gum normally rigged by constraints then combined later? Thanks…
Don't strictly have to combine objects. It's multiple materials that cause increased draw calls. Basically every time the game has to switch between materials, it has to load those meshes into the graphics card, and that loading can slow down rendering. My understanding is if you have a few meshes that share the same…
@"Eric Chadwick" Hey, thanks for the insight. Having the eyes on a separate shader makes sense. I have "glass" corneas, so I'll do this. Unless this is uncommon for games. @"Mark Dygert" Hey Mark, thanks again for the tips! I was getting confused with the UV/shader setup. I did have my UV's done already, but I wanted my…
Fewer meshes means fewer draw calls so as a general rule of thumb it's a good idea to combine as much as you can, unless you have a fairly compelling reason to do otherwise. One reason might be... That you want to pack a lot of detail into the eyes, both the textures and the material (reflection and refraction) but you're…
