# Adjusting Normals

When using transparency with 3D models, you may sometimes see the back polygons, giving the model a shattered or broken look. This happens when the drawing priority of the normals is not sorted properly. Enable Sort and select an option from the Sort Order box to sort the drawing priority back to front or front to back.

Drawing order of the 3D model's polygons is incorrect. Back polygons are drawn through when the model is transparent. | Select Front to sort the polygons front to back. The transparency is drawn correctly.
