Newbie trying to understand what's a standard practice for you experts. I'm loading a GLTF model with multiple objects that change per the user's input. (Change being different material like color or shininess/metalness setting, etc.) I have a color picker that the user chooses from that currently creates a new material each time the user makes a selection of a different swatch from the color picker.

In terms of standard practice - should I just be creating the meshbasicmaterial once, and then changing it (i.e. setting a new color, changing the value of shininess etc.?) Should I be creating the meshbasicmaterial every time I want to change the color, etc.? If I'm creating a new meshbasicmaterial every time, should I be disposing of the previous one prior to creating the new? Or, maybe you do something completely different?

Any advice is greatly appreciated.

Thank you.

Yes. There is no need to create materials over and over again just because a property value changes.

If you don't need a material instance anymore (for whatever reasons), always call dispose() on the object to potentially free internal resources like the respective shader program.
