bsp models size question.

[ceriux]

when loading an external bsp (like the explode boxes) is there a size limit of the bsp? or does the size not matter at all. are there any limitations i have to be aware of? i use darkplaces.

I haven't noticed anything in the renderer that makes a distinction between the world bsp and other bsp models for any limitations. While its usefulness is debatable*, there's no reason I know of you shouldn't be able to load a second map as a non-world bsp model.

* I can think of some, but that would require specially crafted maps to make it worth while.

I already tested to load an entire level (E1M3) inside another map (a simple box large enough to fit the loaded map) as a bsp model (in FitzQuake IIRC). No complaints from the engine side.

nice, but how does collison work. like normal bsp? or is more like the models like the player? id like to load a couple of kind of large structures (damagable) as objectives. not as large as a whole map. will lighting still work properly with them?

collision: since you're using DP it should work OK even if you rotate the BSP (for example, giant cogs or a water mill).
No, alias models use a non-rotating box for collision, BSP models use the model hull for collision, so you're OK for example with destructible stairs or ramps or whatever you come up.
lightining: it's fixed, unafected by world at all (exactly like an ammo box or a health kit works in Quake), so unless you carefully light both the BSP models and the world they'll look ugly. There are a couple engines out there that may support dynamic lights on BSP models, if memory serves me well DirectQ (and consequently RMQe) have this. Dunno if DP does this.

u rotate the BSP (for example, giant cogs or a water mill).

or a drivable boat

you need to use movetype_push to push/carry other ents. this requires using velocity/avelocity to do the actual moving. which kinda sucks.
