Flickering in AO & GI Render

[Brian Jones]

To match what scene AO does put AO in the Diffusion channel (but you can put it anywhere for different effects).
I would put it on objects that need it (the racks etc), try the scene without any AO at all since it’s real reason for existence is to fake GI – that’s not to say that they don’t go well together at times but sometimes both together can be a problem (and I’m not sure that’s what your problem is, it’s just a guess)

So I am having a similar issue, but all of the things suggested here aren’t working, can anyone take a look at my file to decipher what I am doing wrong?

Hi Elias –

Took a look at your scene. Looks like your main light source is an area light. In my experience, area lights always produce flicker in animations. Maybe it’s just me, but I tend to stay away from them for animations. I would suggest using a omni light, with falloff set to inverse square, and some soft shadow maps. Then turn on ambient occlusion, and you should have a fairly similar look. You can adjust the falloff of the light, the ao settings, and the shadow settings to get a similar look. That should take care of your flicker. No real need for GI in the scene. Just some nice lighting and you should be good to go.

Thanks Justin, I will take a look and report back.

I am planning to add dust when the words hit, would you suggest I do it in C4D or After Effects?

It is still flickering. I am going to start over and create a new material to see what happens.

Hi Elias –

I would suggest adding the dust in AE. It will be much easier to create plus easier to adjust/less render time then tryin to do it in C4D. Can you upload a QuickTime of the flicker you are still seeing?
