Blender Exporter Issue

[adam]

Can someone explain this warning to me:

 

WARNING: Maximum # of influencers exceeded for a vertex, extras ignored

 

Why does Babylon set this limit?  I've used this model in Three.js without any issues.

I'm hoping this will solve my issue:

I'm hoping that works when using the automatic weights option in Blender.

Hi Adam w- welcome to the BJS forum

 

With regard to this issue, I've never had any problems with the exporter - or the blender automatic weights option - but I generally keep the number of bones to < 40.

 

The only time you are likely to exceed 40 bones is if you have a lot of finger and/or face bones.

 

I usually use the MakeHuman "game rig" - the Blue Lady.

 

cheers, gryff

I too would like to understand. This is the first time I see this kind of limit. I have already seen the limit on the number of max 50 bones, but, not on the maximum influence.

We are limiting the number of influence per vertex to 4. Which means that every vertex cannot be affected by more than 4 bones.

And for the record Three.js has the same limitation: https://github.com/mrdoob/three.js/blob/5c7e0df9b100ba40cdcaaf530196290e16c34858/src/renderers/WebGLRenderer.js#L1070

 

I think that three.js exporter just do not warn you baout this limit.

I just looked at the Three.js exporter for Blender.  They actually have a setting for this that is set to 2 by default (highest option is 4).
