Ok, now that all generated maps show up in unity, I ran into the next problem: I can´t assign those maps to my terrain composer texture slots; I get the error:
"InvalidCastException: Cannot cast from source type to destination type.
TerrainComposer.draw_terrain (Int32 space) (at Assets/TerrainComposer/Editor/TerrainComposer.js:5601)"
so I thought myself, let´s just output the maps bitmaps from substance, without substance; but when I rightclick the substance and select "export outputs as bitmaps" I get the message "there is no output image to export from the selected graph"
I feel like an idiot
any ideas?
