Blurry textures in Maya
on Oct 14, 2005 at 10:30:05 pm

I take bluescreen NTSC 720x486 footage and key it (usually with keylight) and bring it into Maya on a somewhat regular basis. I've never been happy with the quality of my image planes because it always looks blurred (usually just use a nurbs planar). I know about the filter setting and that helped a bit. I think I'm running into a square vs. rectangular pixel aspect issue in Maya and that's why the textures look blurred. I've been rendering frames out of AE but I'm wondering if I should be changing the comp size to 720x540 and change it from rectangular to square before rendering out to Maya? Anyone have any experience with any of this?

Are you using these images for texturing or for an image plane/background?

I'm using a nurbs plane and doing a normal 2D file texture.

Would you mind sending me a jpg of your render and the original image you are trying to texture? I think I might know the problem, but I wanted to see it to make sure I send you in the right direction.

Did you ever get this solved? I'm having the same problem. I think it's a Maya setting and not the image aspect ratio. I work in video as well so I'm used to square vs. rectangular pixels, but I also bring in image planes of photos shot from my still digital camera. What I *have* noticed is that Maya renders the same image plane completely crisp when rendered with the Maya Software renderer. But it's only with Mental Ray that I get blurred image planes. Hopefully we can figure out why.

I had to render my video sequence out of after effects in square pixel aspect ratio and then I had to make my image plane a 1.3 in X and 1 in Y and scaled it up to what I needed and it was -much- better after that. After effects actually doesn't do that great a job of de-interlacing video but it was okay enough to do what I needed done. There's a fields kit (Re:Vision) that specializes in de-interlacing footage if AE's isn't good enough.

Hope that helps!

Deinterlacing will definitely blur your images. There's a great example in the AE COW articles from WAY back. Re:Vision is good if you simply must try to convert interlaced into progressive. But that's not my issue. I'm working with non-interlaced, square pixel images shot from a digital still camera for my image planes. I've tried them in both JPEG and Maya's IFF format. Both ways get blurred the same when rendered in Mental Ray, b ut stay crisp in Maya Software. I NEED to render in Mental Ray, though.
