why need export materials every frame？

[mop333]

if i render sth in LV ,just export materials once . the other frames dont need export materials.
but if i render in picture viewer in C4d, every frame must be exported materials ,it is takes lots of time to wait.

cauz I need to render animation, the only way is render in picture viewer.
my question is there any way to render once in picture viewer in C4d?
or is there the better way to render the animitiaon?

thx a lot!

Plugin has smart methods to detect and update only required parts of scene. Materials/geometries/etc..
Are you sure that you're investigating correct? It will not update anythings if they don't trigger any change messages.
Are you sure that you're using default render settings? "Auto detect" option will provide the required settings for you.
