4D Publish | Tips for small file sizes

Disable Phong Normals

If you don’t require normals then disable the Phong Normals checkbox when exporting. Cinema 4D calculates normals dynamically in a C4D scene so the file size can stay smaller. Acrobat Reader however needs all the pre-calculated normals within the file itself.

Including normals will roughly double the size of each object in your file.
