I was always under the impression the method to gain access to the latest Pixelmap Layer content in an older show file was to do a Change Type of the old Pixelmap Layer fixtures to the latest revision.
Is this no longer the case? Is there a bug, or simply just a new method? We can’t get the new content to show up.
You have to launch a new show, add & patch a pixelmap layer, and then merge your old show into the new one. This has always been the case as far as I know.
