We haven't had issues with OpenGL renders to EXR and ACES. Is the rest of the color management set up properly in Houdini? Might want to post more detail about how you have things set up and what you are rendering to.

We moved away from Imagemagik as much as possible for this very reason. But between Open Image IO in TOPs and COPs (both have full support for ACES), I haven't found much I can't do that IM did.

OK. I think I've mostly got the frame number sorting figured out. I'll just create a new attribute where fadj = frame + (range.1 * wedgenum). This works as long as everything fits on a single mosaic tile. Now I just need to figure out how to chuck in the inputs so that they tile correctly if the number of wedges is greater than what can fit on a single mosaic. Any help is appreciated.

Also FWIW, if you unselect the "cook frames as a single work item" as you say, then you have access to all the individual frames and in that case, pdg DOES write the frame number to each work item and it's much easier.

The way we get around the caching issue is to add a file node back in SOPs with the same file path that you have in the ROP geometry. That way when the ROP fetch goes to render, the file node in SOPs is grabbing the cached data and it doesn't try to recache.
