Pro Animator Motion Blur has yellow edge?

[Jon Okerstrom]

It’s not happening to me, Mike.

Which version of PA are you using?

Hey Jon,

I am using ver 3.0.2 here is an image I just rendered of it. You can see a yellow edge on the text. This is rendered full frame with alpha, but it also shows up in field renders with no alpha.

Thanks for the quick response!,

Here is an even better image of the yellow outline.

The image helps.

You said you’ve eliminated lighting as a possible cause. Are you using a reflection map on the edge of that text?

Hi Jon,

There was a reflection map on it, great idea by the way, so I did another test on text that has no surfaces applied to it. In addition this was rendered on a completly diferent system as I am home from my studio now.

Lighting is the default 3 lights however I changed the collor on all of them to white.

This is really strange that I am seeing it on 2 systems but you are not seeing it on your end.

What’s interesting about that image, Michael, is that the apparent lack of transparency in the motion-blurred areas. (Motion blur really isn’t a blur – it’s multiple copies of an image, slightly offset based on object motion with varying degrees of transparency.)

Rather than seeing white transitioning to yellow, I would expect to see a transition from white to darker and darker gray. In fact, that’s what I get when I render the project.

The solution may be in your output settings… or something else. If you render the scene without motion blur, do you get any yellow?

Hi Jon,

Here are the settings I am using in the project…

Background is set to black with alpha turned on. Motion blur is set at 4 passes and AntiAliasing is set to 3×3. Render is set to full frame and res is 720×486 with D1 pixels. I have tried various adjustments to these settings but still get the yellow edge.

If I take the motion blur off the yellow goes away. Image below is with no motion blur.

Thanks again for your help,

Mike

Hi Michael,

I rendered your project file with the current version 3 with no issues. Are you using a Mac or PC? If you’re on the PC side, I’d recommend being sure your video card drivers are current.

Hey Jon,

I have now tried it on a third system with the same results. All the systems have Nvidia cards in them and all but one have the most up to date drivers I can get. The one that doesn

Hi Michael.

Would you mind sending me your test file? I’d like to take a look.
