Help with painting texture using slope

Hello Presto423!

Thanks for your message!
Unfortunatly, yes, it might be too beginner for me as I am searching for a way to modify existing very complexe nodes… As far as I understood those nodes from looking at them, there are 2 slope constraints, one for the grass and one for the rocks layer beneath it, but every other layers are locked on those 2 slopes constraints. If they are too low, I can’t paint anything on my terrain. There is no way (as I understand) to add more slope constraints to other materials as those 2 slope nodes are connected to a node which has only 2 entries…
The solution I am thinking of is to set that slope constraint on it’s maximum, import the textures of the layers I want to change and paint them manually… On my whole map, which is kind of very large! XD
Placing things manually often becomes the last solution… I’m doing it a lot on Terragen too! Haha

What software do you use on generating terrains?

Thanks a lot for your help and advices!
