Shading

Adding a bump map to the mia_material shader

To add a bump map to the mia_material shader

1. Create the following nodes: mib_passthrough_bump_map, mib_texture_remap, and mib_bump_basis. You also need to create a texture vector, and it is recommended that you do so by creating the mib_texture_vector node.
2. Connect mib_passthrough_bump_map.message to mia_material.bump.
3. Connect mib_texture_vector.outValue to mib_texture_remap.input.
4. Connect mib_texture_remap.outValue to mib_passthrough_bump_map.coord.
5. Connect mib_bump_basis.u to mib_passthrough_bump_map.u and mib_bump_basis.v to mib_passthrough_bump_map.v.
