General Art Guidelines

This is a collection of general guidelines for importing content into the C4 Engine.

3D Geometry

Any individual mesh must contain less than 65535 vertices.
Meshes casting stencil shadows must be closed.
Joint names must be uniquely named.
C4 uses arbitrary units.
If meshes require a particular direction, the forward vector is along the positive X axis.
It is highly recommended that all scale transformations are reset to identity prior to Collada export.
It is highly recommended that all geometries' history/stack are deleted/collapsed prior to Collada export.
References to texture map files must contain the path in the Import directory that correspond to an already existing tex file. (Otherwise, textures will not show up when importing the Collada file)
Collada animation files can exist anywhere in an import subfolder.
Only animations (.anm) that exist in the same directory as the corresponding Model (.mdl) are viewable in the Model Viewer.
Collada animation files must contain the exact bone hierarchy and names as the source Collada mesh.
