Ok I don't want to be a pain, but I do want to show you one last thing
^ ^'
I am having this issue when adding effects to 3D Object, and I am also getting this when adding Effects to a Sprite with the Rotate 3D behavior.
The object gets cut off either at the top or bottom (depending on object scale and Z Elevation.)
I did manage to work around this by setting the Layer Elevation of where I have the object to 1. But it just about works with the exact values I have for the object scale and whatnot, which is why in the previous message there is no visible glitch on the star. As soon as I change those values a little bit, I get the result on the video below.
One other problem that I get by having the 3D Object in a layer that has > 0 Z Elevation is that if I attempt to rotate it, it doesn't rotate on what should be its pivot point. (what I mentioned on the first comment)
I initially thought that this was a problem with Construct's 3D features in general, but I'm not getting these issues with the 3D shapes.
It would be great if these issues could be fixed somehow.
