Hello all
I am trying to make a 3 texture height blend.
With 2 texture works ok... but i can't realize how to blend the third texture.
Here my shader

Anyone have an idea ?
Thank you!

Hello argenzio,
Thank you for getting in touch!
In order to achieve a 3 way blend, you may use a second lerp node to interpolate between the result of the first lerp node ( first and second height maps ) and the third height map.
I'm sending a screenshot attached for your convenience.

Check your PM for a sample.
Please do let me know if this works out for you, thanks!

Thank you, it helps me a lot!
Now the POM Heights Blends works very good with 3 texture.
Next step is to support height blending based on
Vertex Color.
I try to use Multiply and Add.. but gave me strange blending... what it is the best way?
Thank you for your support.

Hello!
Does the sample shared privately not include support for vertex painting?
Thanks!

Really can't thank you enough Ricardo.
Everything seems to work fine now.. I was really far from the right way.
I will post the result as soon I will finish it.

No problem, happy to help
We should be able to include that sample in the ASE package soon.

Ok I talk too soon.... seems there is a problem with the third layer blend in the example file you send me.
The second layer blend perfectly with the first.
But the third seems to ignore the depth mask.
Here an example, the grass (third layer) grows on top of the stone (first and second layer).
