I want to be able to support multiple textures in my game engine
because using a single flattened texture (with everything burned
in) uses way too much texture memory. I am willing to sacrifice
some performance for much less video memory requirements.
Do you mean combining pictures into one texture -- like decals on a
model -- layering masked picture upon picture before applying it via
Material.Texture?
If this is the case, then what I can share comes from Zombies: I've
seen a delay when combining lots of pictures to create a final
texture. Most of the combining happens before a game starts to create
the humans, but we do swap textures in-game when a human is converted
to a Zombie.
I've never looked into whether the delay comes from combining the
pictures (Up to 12 layers of masked pictures for Zombies) or from
adding the texture to a model.
