Does anyone know how to do a semi-decent flashlight (shining on a Q3Level[hence lightmapped quadtree scenenode])?
I'm thinking something like HL1 flashlight would be OK. I know the HL1 flashlight isn't that great, but it's better than nothing.
Right now I'm just doing a billboard a static distance in front of the camera that's additvely blended (and it's got a texture similar to a flashlight's light). Technically I could have also done a GUIImage. Sounds horrible? It is.
Casting a ray out and putting the billboard at the point of intersection doesn't work well at all, worse than just having the billboard a static distance in front of the camera, since it doesn't go around corners. An HL1 flashlight goes around some corners, but I also know it casts out a ray to find where to put the light, because you can see it "pop" off of the edge of walls onto a wall further into the distance.
