thank your help !

The example works for me on the latest release. From the error, it looks like you are using a pretty old release (0.31). Can you try updating?

If that still doesn't work, can you provide some more details? What platform are you using, etc?

I'm experiencing the same error.

I'm using version 0.35.0 of kiss3d. I'm using rustc 1.66.1. I'm on Mac OS Monterey 12.6.1 (apple M1 chip, Macbook Pro 2022). Any idea what might be causing this @donkeyteethUX ?
