Does scaling of models have impact on performance?

Questions
1

So I usually prepare the models in Blender before exporting them to .babylon format. Because STL models imported to Blender are really big, I usually scale them in ratio 1:1000. If I wouldn’t do this, I would need to edit view distance of Blender to see the whole model. This must have impact on performance I believe. But does it really have impact on performance in the scene of Babylon.js?

Scale has no impact directly regarding the CPU
But it could have an impact on your GPU as if you scale the mesh to render it fullscreen you will have more pixels to render

But in your case you are scaling down so it will actually improve the perf :slight_smile:
