Issue with NME and instances

Questions

Hello!

I am following the documentation about instances from here:

So I have created a very simple scene with some cubes using instances:

Then I have tried to apply a custom material that contains a texture to these instances, and following the docs I have made sure that the instance block is added on the vertex output calculation:

It seems pretty simple, but the scene is appearing with visual artifacts, so I am clearly missing something:

Can someone help me figure out what I am missing here? Thank you!

Looks like an alpha issue: https://playground.babylonjs.com/#WVWIUE#3 Assuming you do not need transparency, so I turned it off.

Another way to disable transparency is to not connect something to the alpha component of the FragmentOutput block: when this channel is connected, the system assumes that the node material should be transparent, which disables the writing of the depth, leading to the artifacts you are experiencing.

Thank you both! I wish I could mark both as answers as they both work :slight_smile:
