Odd behavior with grade layer in a 3D environnent.
I'm experiencing an odd behavior with a grade layer using Hitfilm Pro 11 on Windows.
I create 3 layers from a transparent PNG, in a 3D environment (with a camera, each layer being in 3D too).
Each layer is on a different Z coordinate.
All of them are attached to a point for the purpose of the demo (to easily manipulate them in 3D).
00:01 front most layer is untouched, 2nd and 3rd layers have effects applied on them. When I rotate around Y axis, everything is fine, my effects are perfectly applied on layer 2 & 3. => GOOD!
00:21 I tried to optimize it by using a grade layer applied on layer 2 & 3. Front most layer is untouched, 2nd and 3rd layers have NO effects applied on them, previously applied effects are on the grade layer now.
When I rotate around Y axis, I have an odd behavior with my front most layer beying always visible despite the fact it is behind layer 2 & 3 at some moment of the rotation.
Is the behavior normal with the grade layer, and do I miss something to make it work with the grade layer like in the first test?
Here is a video of my tests: https://youtu.be/uEEMT0NpnYg
And the project file for those interested :-)
