Red lines question

[RockyMountainHigh5]

Hello, I just began using this tool yesterday. I recreated the attached tutorial’s mountain generator but ended up with red lines connecting the bottom half of the generator. I am not sure what is causing this. See uploaded screenshot. Thanks!

guees you trying to pass Bitmap data to Erosion, which work only with Heightfields data

you could fix it by changing output mode inside File Input

The red status square for the File Input means it is not importing data. You probably need to assign an image inside of the device!
