LOD example

[Ji-Rath]

Simple example showcasing LOD capabilities with both Visualization and Processor logic. Edit: This PR should only have changes in the Plugins/LODExample but I made a few oopsies and initially made the mistake of making changes in main. (the reason for a lot of commits listed below, those changes have since been moved to another branch)

• Transitions between actor visualization and ISM visualization using various meshes (Essentially simulating HISM)
• Performs different processor logic based on LOD
• Performs logic at different tick rates based on LOD
• Stops processor logic when culled by frustum

Some additional notes

• This addresses entities disappearing/defaulting to OffLOD with >100 entities, my guess is due to the fact that the LODCollectorProcessor is not on by default
• OffLOD appears to fluctuate between Off and High for some strange reason, I can only guess that it is a bug or possibly a fault in my logic.

I think im being a big doofus and need to relearn git lol My guess is that im paying the price for committing my formations PR in my main branch, then switching it over.

If you have to put them both in one PR, that's fine... May as well!

Ah gotcha, in hindsight i should have done separate branches for my work from the start. I just didn't expect to create multiple PRs so soon. I'll definitely get it right for next time lol

Just wanted to post a quick discovery on the bug I mentioned earlier: OffLOD appears to fluctuate between Off and High for some strange reason, I can only guess that it is a bug or possibly a fault in my logic.

This appears to be caused by a conflict between LOD Distance calculations and LOD Max Count calculations (In SimulationLOD trait) as can be visualized below. (50% speed)

I can't exactly say whether or not this is intended logic. In my opinion, if an entity receives OffLOD from LOD Max Count, it should not be overridden by LOD Distance This also highlights another 'bug' where frustum culling is not considered unless LOD Max Count calculations determine it to be OffLOD.

It should be noted that VariableTicking appears to be unaffected and is solely based on LOD Max Count.

TL;DR LOD Max Count determines LOD. Anything currently in OffLOD gets passed to LOD Distance and frustum culling
