hey @DPI Wizard i have recently had great success with the whole focal length custom res calculations
and at that point i started hypothesizing about a potential implementation of this calculation
https://www.geogebra.org/classic/wg83gxjc
if you could select ^ focal length as an aspect ratio that would be interesting ( keeping the native fov modifier )
and just locking the resolution to the respective custom res
could simplify the application of this process ,it is very niche so it not being viable option would make sense
interested in hearing your thoughts on it
keep up the great work
