Always show model

I have two models.

- close to me

- far away from me than model1.
- be obscured by model1.

How to see model2 always?

The question is a bit confusing. Maybe you are looking for LODNode, which handles hiding and unhiding objects based on distance.

If I understand you correctly, you want to have a specific object be visible regardless of any geometry that might lie between it and the observer.

In that case, you might find that placing it in a later-rendering bin and calling “setDepthTest(False)” does what you want.
