[Feature request] Abrupt visibility switching between models instead of proper per-splat occlusion

[RobLinkA]

Current behavior:
When multiple models are placed in the scene, their visibility relationship switches abruptly as a whole based on camera angle, rather than having proper per-splat occlusion. This creates unrealistic and jarring visual effects.

Steps to reproduce:

1. Import two models that spatially intersect (e.g., a character model and a vessel)
2. Slightly rotate the camera angle
3. Observe how the entire model suddenly switches between being fully visible or fully occluded

Example scenario (see attached screenshots):

• Screenshot 1: The character model is completely visible in front of the vessel
• Screenshot 2: After a minor camera rotation, the same character model is completely occluded behind the vessel
• This binary switching occurs instead of proper partial occlusion where models intersect

Expected behavior:

• Splats from different models should be sorted and rendered based on their actual 3D positions
• Parts of a model that are spatially behind another model should be occluded
• Parts of the same model that are spatially in front should remain visible
• This occlusion should be continuous and smooth as the camera moves

Impact:

• Makes it extremely difficult to position models accurately
• Creates unrealistic visualization where models intersect
• Requires constant camera adjustment to check spatial relationships
• Significantly hampers workflow when creating complex scenes

Hi @RobLinkA ,

This is a top priority for us as well. Unfortunately it will take some work to implement, but we will hopefully get it done early next year.

Great! Looking forward to it!
