Title: textured, uneven light like in youtube tutorial
Post by: dacian on 2021-06-25, 10:44:46

In this redshift tutorial, at 3:48 they're making a light with a texture on it so that it projects the texture on the background wall. How would we go about getting this effect in Corona?

it's possible with textured & fully directional Light material on a plane
but it tends to have soft shadows, is quite noisy and produces lots of fireflies

You can also use a C4D light and apply a C4D material to it. Note that this will not be visible in IR, just the final render.

any other solution for getting that effect with good quality and full IR compatibility?

A plane with an opacity texture, behind it an Corona area light. Mimics the way it works in reality and works with IR.
