Seems like the subdivision modifiers are ignored.

(if these are applied, everything works as expected -- and no, this does not have to do with the fact that on one of the modifiers we dont have the same render and viewport settings -- the subd just seems to be ignored entirely)

Hi! I have tested the file, and the cause is probably in updateDepsgraph() callback I only get ob->type == 0 in this file, which doesn't happen for any other files in my device. Not sure what caused it, but the result is that object geometry was not linked with line art modifier by depsgraph so you get raw mesh instead the one that went thought modifiers.

I'll take note and see what I can do. @antoniov Have you experienced anything like this in the modifier?

I have tested and any subdivide modifier after LineArt modifier works, but I never have seen ob->type == 0 before.
