Hi everyone!
I have been trying to use a custom projection matrix to the Camera COMP in order to achieve reverse perspective.
Quite surprisingly, after getting the math to calculate the matrix from Chat GPT, allowed me to get the effect to basically work. There are details to iron out, but in principle it works.
However there is an issue.
STEPS:
1 - I create the matrix
2 - I go into the view panel of the Camera COMP and change projection from Perspective to Custom Projection Matrix.
3 - I pass the matrix to the Proj Matrix /CHOP/DAT parameter
4 - The effect works
5 - I try to move the camera via the view finder and the Projection parameter in the View panel resets itself to Perspective
If I change the camera transform parameters the custom proj matrix stays applied to it seems an issue related to the interaction with the viewer and how that is applied.
I can clearly see how I might be missing something and I am not doing all things I should do, but for the love of me I cannot find any article, documentation or similar that discusses in details how these custom matrixes work. But what I would expect is that interaction with the viewer should still be available.
Can anyone direct me where I could learn more about this or does anyone have any suggestion on how to fix/address this? Thanks !
