[BluePrintRandom]

UPBGE breaking thresholds

pretty much anything you ask me to.

and can provide examples if needed.

Would you be able to provide most of the writing? I'd love to get some to do a full revision of the book and get some fresh content including UPBGE features.

Sure, how do we format it? (new pages or a new book or just edit in?)

static mesh batching - could use documentation

reinstancePhysicsMesh(mesh,object,unique) could use documented

breaking thresholds for rigid body joints is nice

spawn groups instance now work with physics constraints now I think
(ragdolls)

using KD Tree or mathutils noise and BVHTree in Upbge is pretty handy

cube map reflection are nice

anything else you can think of?

I would try to work it into the the existing chapters (mesh batching > cha 5; reinstancePHysicsMesh > cha 6; etc). I'll need to start doing a full review of the text and clean it up as best as I could.
