@Jamesol1 I don’t understand your question. Here’s my interpretation.
- So you want to import a heightmap using file input, then you want to import a texture (using another file input) to overlay on it?
- Or you already have your heightmap set up as a terrain, and are trying to import “texturing masks” using additional file inputs?
- Something else…
If #1 is your problem: Switch the file input containing your RGB texture to “RGB bitmap” mode. Click the dropdown labeled “Heightfield” to switch the mode. To view it overlayed, add a “scene view” node and plug your heightmap and texture into it.
If #2 is your problem: Same process, but keep the second input in “heightfield” mode. Plug your mask into a “colorizer” node to map a gradient color to your mask.
If #3, please describe your problem using screenshots of what you have so far, and your node settings etc. A problem with a picture is easier to diagnose.
