Help with flickering problem ...

Postby mastaseth on 07/18/2016, 12:27 pm

Hi, Im working on the following project, its in the early stage of development, but I have problem with flickering lights (again).

You can see that iluminated lights are flickering, all getting worse, when lights touch the end of the screen, you can see it clearly on left and right end of the frame.

Can anybody tell me, what Im doing wrong, what settings use, or anything??

Are the light within element or are they seperate?

The Element glow tends to flicker with smaller lights and (along with the reflections) flare at the image edges. I don't use the built-in glow in such cases.

Try rendering an illumination pass separately and using a blur on it instead.

If I get the question right, the lights are in element.

Thanks, will try this aproach.

Normally I'd wait a full 3 years before replying, but I'm here today...

I found that I had to do a Specular pass because my Illumination pass was empty for some reason (no idea why - things should be illuminated. Perhaps because they weren't illuminating?).

Anyway, adding the rendered Specular pass with glow did the trick for me. Thanks, star+circle.

Early bird....

Yes, if the texture doesn't have illumination turned on, specular will do the job, you get the highlights. Illumination is specific to the illumination channel (surprise!) of the texture.
