Hi,
I'm new to Houdini (but I've worked with Blender before) and can't figure out how to get proper shading on my models. I would like a clean and flat look but as you can see in the screenshot it doesn't look great. My points all have normals, UV, tangentu and tangentv before being exported to a GLB file using the ROP GLTF Output node.
What am I missing?
Thanks!

Use the quickshade node or a principal shader material setup when you export. It will only accept principal shader when exporting.
