I would like to make my foliage invisible below a boundary on the Z axis to create an automatic transition or fade out.
Currently, my approach is to create a material function that gives me a 3D box mask that cuts off everything below 0. It works great, but I’m having trouble combining it with the opacity mask from the Foliage. With the Append Node, I unfortunately lose the mask for the grass itself.
Is this the completely wrong approach for such a scenario? Does anyone have any experience with this?
Thanks for your help in advance!
