Overview

This page includes additional tips and supplementary information to help you use Copernicus.

Clear GPU and memory usage

You can enter copcache -c in the textport window to clear your GPU and memory usage. This also recooks your scene if you have images displayed in your viewport. See copcache for more information about this HScript command.

Move SOP into image space

When you import a SOP into COPs using SOP Import, the geometry is placed in world space. To frame geometry into the canonical camera’s view, you can use the Rasterize Setup COP. Wire your input geometry into the COP’s source input and adjust its settings to get the desired framing.

See Spaces for more information about spaces.

View pixel position

You can view the pixel positions of a node in the Composite Viewer. Make sure the node’s display flag is on, and then and click Inspect in the Viewer. Hover over the image to see the pixel details.

See Inspect individual pixel values for more information about using this tool.
