You guys were so helpful, I figured I'd come back for more! I upgraded last night to PA6 and found something I couldn't explain.

Using any of the AA blurs, +0.6, +1.0, +1.5 (Invig Renderer) I'm seeing these artifacts in the lower right corner as the camera moves down (Y axis camera move). Tested at 3x3, 4x4, and 5x5. Using no blur is clean.

My last issue was user error so I'm figuring I'm missing something!

Hi Austin,

I don't believe I have seen this before, but I'm wondering if it may be lighting that is a part of this. Would it be possible to send the project file to me? My email address is

If you need to render the project in the mean time, you can try using the 3x3 antialias setting, then applying a slight blur in After Effects as a workaround.

Thanks, you and I came to the same solution actually. I just rendered using 5x5 and applying a Fast Blur @ 0.6 and the same basic result as doing it in software. Not a big deal, I just wanted to pass it along to you guys. I'll also shoot you the project if you care to look at it, but sounds like its known issue at this point.

Thanks again for you guys being so quick to reply.

Hi Austin.

There is currently a bug with the +blur option, creating streaking artifacts in
some situations.

We suggest rendering without blur and then doing it as a post-process.

Let us know if you have more questions.
