Hey y'all!

I am trying to create a tool that allows me to place plants onto a terrain using the layers from the landscape material. Has anyone figured out a way to read the paint information from the landscape mat and pass it to an HDA?

Thanks!

Hi,

If a landscape has layers, they will be available as masks on the Heightfield created by a landscape input.
ie: layer “grass” will be avaialble as the “grass” mask in Houdini.

So you simply just need to use a landscape input.

Dude! Super nifty, thank you. I wasn't able to see the layer information when making in Houdini, but when I coded it in, it worked like a charm.

For anyone who is wondering, the simplified version is once you have converted the heightfield to geometry in Houdini, the layer information is transferred to the points. Simply put a point wrangle in and write something like this:

if(f@grass_layer > 0 (or input your own threshold))
{
//run code you only want to run on the grass layer
}
else
{
//run code you want done to the other layers
}
