For this it would also be nice to read the existing material names and their
definitions, and support overriding the materials somehow.
import
{
obj "plane.obj"
usemtl "plane.mtl"
material "surface"
{
texture
{
pigment { ... }
finish { .. }
}
}
material "glass"
{
...
}
material "tires"
{
}
}
Not a very good syntax, but something like that would be nice if loading
external model data.
