Hello,
 in Poser 6 (with Firefly) when I render DAZ Cyclorama backgrounds they always appear blurred if compared with renders with Poser 4 option (Anti Alias turned off).

Is there a way to sharpen the image with Firefly/P6? (Depth of field is always turned off).

Thanks for help

It's probably your Maximum Texture size. Simply increase it in the advanced feature of the render settings.

Also, something else to try it out is connecting the image node to the ambient color, instead of diffuse, and adjust the ambient value to somewhere between .5 to 1 depending on your scene and lighting.  I know this probably has nothing to do with render being blurry, but in Poser 6 and 5, Daz'a cyclorama renders much darker than in poser4.  Just something else to keep in mind.

Also... what render settings do you use? The default one is what you can call "draft" mode, it blurs pretty much everything.

Thanks guys!

Indeed it was the Maximum Texture size
