Hi all, I'm transferring Cd attribute (but it can be any kind of attribute) from an animated sphere to a grid, as you can see in the attached file. Now, as you see, the red is transferred every frame, but we lose the red on previous "painted" prims. How can I still have the red on prims previously painted? In the file I propose a solution with the use of FILE SOP nodes, a simple trick: Houdini transfers the Cd Houdini saves the geometry (the last FILE SOP) Houdini goes ahead one frame
