Thank you for the reply.
My main problem is that in UE 5.5 i was able to do various BP_PCGBiomeSetup and set up one Biome Volume which generated multiple Biomes inside a Volume.
In 5.6 the Setup Blueprints are not working anymore.
It seems that I have to go one Layer at a time (per PCGBiomeTexture)… which will be a mess, because I have more than 100 layers…
Going back to 5.5 is not really an option, because I want to use some of the new 5.6 features for other things.
