fovo - non linear projection rendering

[s0real]

ah ok, i was working on a project in 3.6 where the physical camera doesn't have the same lens distortion rollout as in vray next.

physical camera from max will work with .lens files

i wasn't able to get the .vrlens file you posted to load as a texture under the "lens distortion" rollout, only under "vray properties / lens distortion" - in which case it didn't work with RT / activeshade.

no matter, i've switched the project over to vraynext/max2020 now

you’re right, 3.6 and RT, I missed that.
anyway. texture slot requires bitmap describing distortion. more flexible between applications but stick to .lens files in VRay I guess.
you can also edit the .lens file in VRay’s Lens Analysis Tool to fit your needs.

thanks - i've had a look at the lens analysis tool but don't really understand how it works yet. need to do a bit more reading / find some tutorials.

one more thing for anyone interested in extreme fov:
