ZDoom

These snapshots can't persist across game saves and hub travel so this feature can't be added for technical reasons.

Ah. Then I will use them liberally Snapshot mode would still be useful, tho.

Only when they are onscreen are they recalculated.

It'd be neat if setting camera to texture could take 'snapshots'. That is, capture one image from the camera and then leave the texture alone. This could be done either with another arg to setcameratotexture to indicate take only one image, or by recognising a camera tid of -1 to mean stop.

On a related note, do these camera textures need to be generated every frame, or only on frames in which the player sees them?
