I’ve only started very recently experimenting with BabylonJS Is there any default unit in BabylonJS for 1 Vector ( = I mean, the distance between 2 vectors )? Like, is it the distance between 2 Vector3’s supposedly 1 meter ? Or is there nowhere nothing that assumes this, and can I therefore decide for myself that 1 vector will equal 1 centimeter in my world, without ever running into issues? ---

Hi, 1 vector = 1 unité. It’s up to you to define your unit (km, m, cm, mm) ---

Yes! 1 === 1 🙂 It depends on the model(s) you are loading, depends on how you define your scene. Just wanted to add - in WebXR - 1 unit = 1 meter ---
