Sharp, flickery edges?

Postby subtracticus on 07/13/2012, 9:48 am

So this may just be a limitation of the OpenGL rendering or something, but the edges of extruded text seem to have a computer-y looking crispness to them that causes them to flicker distractingly when they're in motion, mostly if they're on a diagonal I think. In the Output options turning up the FXAA helped a bit, but at the cost of making things a bit blurry. Is there any solution to this? Are other people noticing it?

I'm on a MacPro with a Radeon 5870, working in CS5 using the latest update of Element.

I'm having the same issue. Edges are noisy and flicker when the type or camera is in motion. Some textures are worse than others, but I generally see it in every texture I've tried. Looks like when a 3D render's samples are too low. Has anyone else encountered this?

I've noticed this as well..it's kind of hit and miss. I found that by working at higher resolutions and scaling the render back down helps. I'm currently working at 2560x1440 square pixels. The smaller the 3d object is, the worse it gets. I'm trying to figure out how to get element to respond to the scale comp script, so if there are elements that are crawling too much, I can render out an upscaled version of just that element with an alpha channel and bring it back it as a 2d scaled down transparency, thereby gaining some resolution...

Yes with high contrast lighting and reflections there can be some aliasing from OpenGL. There are some tips for managing this that I will be posting soon. Best!

Thanks dude! I look forward to hearing your ideas. I work in the movie trailer industry, so I'm always creating 3D type for trailers. Using Element would save so much time.
