Title: CoronaCamera and distorsion map bug
Post by: cecofuli on 2018-02-22, 19:13:31

Hello,
I think there is a bug in the Camera Distorsion map.

(*) I created, procedurally, a simple Distorsion map by adding two Gradient Ramp maps with CoronaMix (Mix Operation=add). Everything is ok (no artifacts)
(*) Later, I changed the Tile parameter in both Gradient maps. As you can see, now, there are some artifacts on the borders.

I created the same Distortion map in Photoshop and the result was the same.

Could this be because of blurring? Can you try setting blur value in the texture to 0? (or 0,01 as 0 is probably not possible)

Yes Maru, same result with Blur: 0.01
