Post-processing Issue

[jitendra]

Hello octane Team,

New postprocessing feature is really great.

ISSUE1: I have attached Picture1.png showcasing an issue at borders with post processing applied. There are some gradient borders are generated while the post processing is applied. (Offcourse there is not vignetting is applied)

ISSUE2: The glare generated is not displayed over the transparent floor (i mean alpha). Checkout Picture2.png This might be done necessarily, but would be interesting to have a function where this is displayed over alpha, so can be used for post processing.

Thank you.

Its more visible especially with increase in glare power.
Thanks.

+1 for alpha contribution of Bloom and Glare.

the gradient may simply be an effect of your lights not shining there/not being reflected in the ground. try adding a large mesh emitter overhead and setting it very low to see if the reflection of the emitter fixes it. Try moving your lights, or if its an HDRI, rotate it to see if the gradients move, if so its cause by your lights.

have You disabled vigneting? I believe it might be contributing too..

Friends,
Vignetting is already disabled.
I am using HDRI and I tried to rotate and replace but the effect stays.

Oooh ooh I know! I've had this problem too but wasn't sure why, but I believe I just figured out why.

Okay so because the bloom/glare is just working off of the pixels you render, it doesn't know what pixels are outside of the frame (probably assumed as black) and therefore don't contribute glow to the scene.
