Hi im having trouble booting an older project with substance materials. Ive updated everything to UE 5.3 and installed latest plugin but when booting any project with existing materials from substance, it fails. Is there any way I can get around this?

Thanks

      Try to delete all generated textures and _INST file. Next, follow this steps: "Right-click the substance instance factory and choose "Create a graph instance." This will create an instance of the graph and create another UE5 material. Delete the newly created UE5 material as this will not be used." It helped me.

      when I import the materials into another project, the .uassets that is. It comes in but I get a "orphan graph instance, instance factory missing" on the substance graph file.

      any help would be appreciated
