Orthographic-Cylindrical Camera in Karma XPU 2026年3月31日16:52

A spherical/polar lens that had the ability to independently set the horizontal and vertical FOV, as well as optionally set either of them to orthographic, while being able to render to any resolution or aspect ratio would be amazing.
That would cover most permutations of polar and cylindrical lenses in one go.

I'm not a fan of tying FOV to aspect ratio. Unless you mean the aperture aspect ratio and not resolution aspect ratio.


I've had a fair few cases where it's been necessary or at least advantageous to render a specific horizontal or vertical FOV at a specific resolution/aspect.

Fair enough. Good to know it's coming though! Thanks

Is is also planned for XPU to support custom lens scripts in some fashion? Octane can do it with OSL for example.
