Title: Visibility Track
Post by: SHORT CUTS on 2019-12-09, 15:54:44
Hello,
is it a known problem that somehow corona doenst take the visibility track into account? I have an object which visibilty is animated, basically its set to 0 most of the time and then jumps to 1 in one frame. The problem is that the object is still visibile the whole time its set to 0...
Found a similar problem which was solved unfortunatly it had something to do with SSS and transculency which i dont use (index.php?topic=21309), its a rather simple material.

material of the object: http://prntscr.com/q8cw3a

screengrab of the curve editor and IR: http://prntscr.com/q8cthf

any pointers whats wrong?

Found the problem...tried a simple object with the same material and it was working so it must have been something with the animated object. It was animated using a path deform using the stretch value and while it was set to 0 the object was still visible, setting it to 0.001 fixed it and the visibility track is now working as expected.

So dont use a value of 0 if you want to animate the visibility...

Sorry for the inital post, you can delete this whole thread if you want.

I'll just move it to resolved in case someone else has this problem.
It doesn't seem to be Corona-related, does it?

Doesnt happen with vray so i would guess it has something to do with corona.
