Help with missing normals

It appears that if a textured model does not contain normals, the pipeline tool will just create content with only position/texture coordinates.

You can force it to compute the lighting data by setting “GenerateTangetFrames” to true.This causes the pipeline tool to calculate the normals + tangent + Binormals.

The problem with this is that I only require the normals and I am using large models with a lot of vertex data so the extra tangent/binormal data does kind of matter.

Is there a way to force the pipeline tool to compute normals if they do not exist - to create an XNB with only Position, Normal and Texcoord data?

FYI the source model is an FBX file


Maybe you could import your model to Blender and calculate the normals there?
