I'm creating DEM rasters (1m cell size) from Lidar using RasterDEMGenerator.
Then Hillshades from the DEM rasters using RasterHillshader.
I'm getting hillshades that look like stacked contour layers.
I believe the hillshades "should" be smooth surfaces (especially Lidar surfaces) so I'm not sure what I'm doing wrong.
I've attached my model and sample output.
+44One option would be to reduce the cell size to less than 1m. It would still be "steps" but they would be smaller and less obvious.
Another option is to build a surface instead of a raster DEM. Actually, you'd need both, because the HillShader works only on rasters. So create a surface model, create the DEM and hillShade, then add the hill shading onto the surface as an appearance.
I think it would look something like this:
I think that would be an improvement. It's how I'd first approach the problem, for what that's worth.
Thanks,
I gave this a try. I probably need to mess with parameters as it still has the stacked contour layers look.

Hi. I did a live stream demo of me trying to solve this problem, but I just couldn't recreate your stacked look! You can find the video recording here: https://www.youtube.com/watch?v=bjZRcyYuOjU&t=256s - towards the end, I do have a couple of thoughts about what else goes on in your workspace and how that might affect it. I hope it helps.
