1163          important differences.  First, proxy geometry is not
1164          supported, so there is no thickness parameter.  Second, an

1167          which is treated specially during the direct calculation
1168          and when viewing the material.  Based on the BSDF data, the

1183          If a material has no specular transmitted component, it is
1184          much better to use the BSDF type with a zero thickness
