Quite suddenly, all my Daz 4 renders to screen are coming out blurred, even the quick start scene containing only the Genisis model. I have checked the camera depth of field and it is turned off. Resetting the defaults in the preference section didn't cure the problem. I have not yet checked renders to file or to Photoshop.

Any suggestions

Check the Advanced Render settings, your shading rate should be around 0.2, the higher the value the lower the quality of the render. Also check what your pixel filter is set to, for most things it should be on "Sync".

I've checked the two settings. The pixel filter was set to triangle. Goodness knows how that happened. Resetting it to sinc cured the problem. Many thanks
