I’m doing some job for my school project and in 1 scene (file) I have problem with subsurf modifier, when I add it, nothing happens. If I try apply it, it writes
Modifier is disabled, skipping apply
Other modifiers look they work, and Subsurf in other files as well, but in this case, I have no idea where is the problem.
Here is the example http://leteckaposta.cz/846978693
Please help me.
