I'm trying to make a "heightfield displace by files" node that has Copernicus as core system for layering. I'm using a COP block and timeshift SOP to layer textures based on a multiparm of inputs and settings. This all works fine by using $F to refer to the attributes. However where I get stuck is the ramp. I cannot dynamically set the ramp based on frame as i get the following error if I try:
Warning: Parameter '/obj/ue_pdg_terrain_test1/heightfield_file_noises1/cop_seeding_texture/util_cop_slopemask1 Ramp' cannot be animated or time dependent.
Is there any way to have the current iteration of the layering refer to the correct multiparm ramp instance?
