How should I refer to this topic if the Playground is only used for loading GLB files?
This Playground, too, does not render its backside. Although the red sphere appears to render the backside, shouldn’t it also display the back corresponding to the red line? As for the blue sphere, it appears transparent due to missing mesh parts, but it also does not render its own backside.
I found a topic discussing this issueFrom what I understand, it seems that BabylonJS does not natively support such a feature, and one would need to use tricks or custom shaders to replicate this functionality.
