Mesh clear split normals data?

Questions
1

Hi, I was wondering if there’s anything available similar to Blenders “Clear Custom Split Normals Data” feature in the Geometry Data menu that can be applied to a mesh?

Use case: I’m merging a number of meshes (flat & smooth) and the end result is being shaded as either smooth or with incorrect normals, I can’t tell which. I already experimented with exporting the base meshes from Blender with no custom split normals, but I think the Mesh.Merge adds them incorrectly. Loading the merged mesh as an exported .glb inside Blender and clearing the split normals data fixes the issue. Unfortunatelly I need the merged mesh at runtime and cannot post edit it.

Did you try to add a ComputeNormals block? Wanna share the graph on nge?

I assumed it was in NGE because you mentioned menu but maybe it is only using code? In that case please share the Playground so we can see the code :wink:

Hi, I tried to recreate a playground but the issue does not reproduce with basic 3D models. At this point I don’t know if it’s an issue with the Merge(), I was just asking about a feature. This post somehow relates to what I am talking about. New smooth / flat shading processing

Without a repro I cannot really help you unfortunately ;(
