Light blocking by doors

(r3tina) #1

I’ve used a door as a platform, to enable me to control it’s movements better than is possible with a func_plat. The problem is that doors don’t block light, and thus the floor underneath the platform is much too bright.
Is there a way to make doors block light, or is it perhaps an idea to add an entity key to q3map2 to choose whether a door blocks light or not?

Put an invisible, nonsolid but NOT trans shader where you want a shadow cast. Example:

textures/r3tina/shadowcast
{
surfaceparm nonsolid
{
map $whiteimage
alphaFunc GT0
alphaGen const 0
}
}

ow, that’s an obvious solution! Thanx for doing the think-work for me Ydnar :slight_smile:

wouldn’t that alphafunc impose a performance hit? I mean, the surfaces are still drawn, but blended out with the alphafunc.

edit: the option to select if an entity blocks light or not would still be a good idea IMO :slight_smile:
