Hi everyone,

I always start to struggle with multiple boolean operations and normals. Is there any best practice workflow on how to do it right? Attached is my loot box that kind of looks wrong I just placed the normal at the end.

Always make sure vertex normals exist before any boolean. Computing normals after a boolean will produce poor results because the mesh will no longer be composed of quads or tris.

Thanks jsmack,

I have added 3 more screens

1. Before the Boolean it looks like this. And I think it looks right.
2. The geometry I want to use for Boolean
3. The Result.

What am I missing?

Vertex Normals. Your screen shot is showing prim normals which are NOT attributes and have no meaning here. Check the geometry spreadsheet or node info for the presence of vertex normals.
