Where to place Layerblend on AutoMaterial to Paint on it? MatLayerBlend_Stanard

Hi everyone,
I have a some unusual question and I hope someone can give me tipp or an answer on it.

I use the “MatLayerBlend_Standard” function to generate a landscape in layers.


Which shows different textures at different angles and heights of the landscape.

It’s really a blessing that I don’t have to paint the 72km² one by one :smile:
…and it looks good at first view

Now I would like to implement the created LayerBlends to paint over the surface,


but I encounter a problem there.

Where do I have to add this to the auto material function so that it always remains paintable?

I tried everything. Add First positon in the Function, to the current function… No success.

I would be very happy about a tipp or an answer and thank you in advance.

Kind Regars
Tobi
