Dynamic lights on moving brush models

COOL!!!!! I'll try to try this in software.
a good place to test this is dm2's moving platform


In software, the R_DrawBrushModel equivelant is R_DrawBEntitiesOnList in r_main.c
i'm only a bit lost on the matrix translation

SuperCool! So, if I understood correctly, if I use Ode, I could make a swinging lamp which castes real time shadows(like far cry did in a map)?

I've been looking over the software Quake source and it seems that further work is needed for this.

As I understand it, the basic loop goes something like this:

- Identify which entities get drawn
- Mark lights in the world
- Mark lights for entities
- Build surface caches for the world
- Build surface caches for entities
- Draw the lot

The problem here is that the "transformed" member will go out of step - it's necessary to retransform again during the surface cache building stages, for both entities and for the world.

Thanks Chip for the hint but I didn't want to cast fake shadows, I want to parent a real light to a model, so wherever the model goes the shadow will cast realtime shadows

there's some tenebrae extension that allows you to attach proper realtime lights to entities, but you might need stuff like MOVETYPE_FOLLOW if its a bsp entity.

Thanks Spike! I'll try it and post results in another thread not to spoil this one!

I just applied it to Engoo's shadows!


It's now in svn but i believe I hit a wall lighting bug. I tried to apply this onto the faster lordhavoc marklights function,
