Render and Material ID's

[jvparc]

Hi all,

Just a quick question. Does the quality and/or pixel size of the render affect the quality or accuracy of the render/material ID outputs?

Thanks,
John

The pixel size, yes. But no other parameter as I know of.
You can make a very fast render to get this at a very high resolution by disabling GI.

Cool, thank you so much.

Only keep in mind, if you disable GI and parts are in the dark now, than this edges are not fine sampled like before. In this case it can help to choose a fixed sampling rate.
