Geometry Input - Mesh Normals not updating

by Anders Holden Deleuran

Jan 22, 2013

Hi Daniel,

I just picked up Kangaroo again for a project and noticed that if one uses a mesh as geometry input, the dynamic mesh output does not update/calculate the mesh normals. I've attached a file displaying this behaviour.

Best,

Anders

    Hi Anders...nice little workaround you put in there.  (My guess is you're already doing this, but for others for whom this may be an issue in the meantime) if you're passing this into a script and want to fix it there, just call in order:

    InputMesh.FaceNormals.ComputeFaceNormals
    InputMesh.Normals.ComputeNormals

      Thanks for pointing this out - I thought I'd changed it in the latest release, but had forgotten the FaceNormals.

      Fixed now for the next release!
