Weighted normal missing in fbx

ColMatrix · Feb 12 2025

Hello,

in 3ds Max 2025, I useweight normals on my objects to assist in correct smoothness - works a charm! Unfortunately the weighted normals do not seem to be exported in the fbx. I have tried modifier 'Turn to Mesh' without any sccess. In 3ds Max all looks good.

Can anyone help?

What are you using to view the fbx and what are your import and export settings?

Hi Noren,

Thanks for relpying! I always view the fbx in 3ds Max before passing it onto the unity developers.

Here are my fbx export settings:

Looks fine to me and worked for me when doing a quick test right now. What are your import settings? Try to deactive Smoothing Groups on import. Not very intuitive, I know.

Worth checking the fbx dialog is set to Media&Entertainment . Helped me few times with 3dmax glitches and smooth groups should be definitely off for import. Otherwise any custom normals would be ignored.

That is being a friend. (yes golden girls was in the back of my head after this post and no i am not super dooper old, i watched a lot of "mature audience" material as a youth.)

This worked for me! The smoothing groups option was active, therefore removing the smoothing groups.

Thanks for all your responses!
