Landscape Material Video Tutorial Part 2 – Procedural Puddles

1. Thanks for the tutorial. I seem to get an error at the very end of the second tutorial (right before you paint puddles on the landscape)

   Function puddles_material_layer (Node If) If input A must be of type float

   I get this error in the main terrain material not in the puddles material function. I believe the cause is that the lerp output of my height-mask is a texture when it needs to be a scalar (to match my scalar material expression input in the puddles material)

   Is it possible to map the lerp output to a scalar or is it more likely I screwed up in my puddles material and this is just a symptom? If the blueprints are available somehow I could also manually compare mine to yours.

   1. Hi! Glad you like the tutorial! 🙂
      Are you using a single channel (R, G, B or A) as the input for your if? That should fix the error. Let me know if this doesnt help. It works for me since my whole heightmap is stored in the R channel of a packed texture.
