Hey, I'm loving the new Copernicus nodes.
One thing I'm struggling to do easily is to import a SOP attribute as a non-filtered pixel map (one pixel per point).
This would be very useful for shaders and realtime work (for example, dynamic deformation maps).
Am I missing a node or is this still a WIP?
I have tried the not so elegant method of transferring the attribute to a colored grid of points or squares in SOPs before and trying to rasterize it, but it's proving impossible to get a 1:1 corresponence in COPs.
It's both difficult to match the resolution with the Rasterize Settings node (it always seems to be either slightly offset or mis-scaled despite matching the sizes or using UV), or there is interpolation happening which destroys the data.
Has anyone figured out a good workflow?

Hi,
Here's one way to do it with OpenCL. It reads the point/prim attribute from the grid point/prim with the same index as the current pixel and writes the value into the output layer.
Hope that helps.
