hello,
we are working a lot on scenography and museum projects and something is realy missing for now:
Would it be possible to create a light object generator that simulate a picture or video projection, with the same settings we can find in real life ? (zoom, lens shift, focal, focus, distortion)
(or maybe i just don t know how to do and please telle me ;)
thank you

If it's just about picture/video projection, then you could use 3ds max standard lights (not physical and not Corona ones), those have projector option, where you can paste your image or image sequence and it will project it through 3D space like in real world.

This was discussed in this thread (https://forum.corona-renderer.com/index.php?topic=23444.msg142781#msg142781).
(zoom, lens shift, focal, focus, distortion)
Going through that list:
- Zoom / focal length can be adjusted inside the 3dsmax spot light, it has native controls for that
- Focus: The 3dsMax spot light includes fall-off in it's parameters. As seen in the linked post's image.
This allows you to simply blur the spot light texture input and together with the fall off creates how a defocus looks in real life. (Blurred image + unsharp boundries that tend to go more and more towards a circle shape) - Lens-shift: I gues you mean keystone correction? That has to be done via Node editor before piping into 3dsmax spot, it doesn't have controls for that
- distortion: agian everything through material editing
Don't forget to include Corona Shadow in the Shadow paramters rollout.
Other than that you could get a super computer, turn on caustics and and put a lens in front of the spot light in 3dsMax ^^
