buzzing lines on texture maps

[zoltan77]

Hi,

 

I'm having a problem with texture bitmaps where any image that has fine lines in it will very obviously 'buzz' when rendered out. If I look at a still frame of the render, an approx single pixel dark line across a light background on the map will render very noticeably stair-stepped and aliased.

 

Is there way around this? I can't find any setting that will render maps properly smoothed. I don't think this is a field issue, I'm not rendering to fields. its a very simple scene, just images and movie clips mapped onto a cube, mostly defaut setting for everything.

 

thanks.

difficult to answer without seeing an image

 

It could be your AA settings, or your sampling settings in your material.

 

can you post a sample so we can see ?

I think what you are referring to is a moire pattern.

 

You can reduce it by adjusting the Blur Offset ( found directly under the Tiling Setting ) from 0.0 to 0.02 (+/-) You will have to experiment here. Going too high will blur the map too much.

 

Good luck

that did the trick! thank you so much!

 

I have to go to .003 to take away the moire altogether, and unfortunately it does noticeably blur the rest of the map slightly. But the moire only shows up when the camera is farther away from the object, so as I move closer to it I can animate the value to bring it back into focus.

 

best,
