Hi,

I created a simple example of instanced buffer geometry:

 ![2019-11-11%2018_53_30-obj-three%20-%20Opera](https://canada1.discourse-cdn.com/flex035/uploads/threejs/original/2X/8/8db0570ece9709ea1307791777be8ccd5002346c.png)  
It’s a simple cube, each instance has a “color” instanced attribute and an “instancePosition” instanced attribute. Is it possible to display the edges for each cube or the edges for each triangle?

Thanks

Hi!  
If I got you correctly, take a look at this forum topic:
