There's not much support for projective textures in hl2, from what I understand it's an optimization, because checking where to project the texture is more expensive than simply projecting it both ways (i'm not 100% sure why that is, something to do with the depth buffer I think) but someone correct me if I'm wrong.
From: Greg Houston <[EMAIL PROTECTED]> Reply-To: [email protected] To: [email protected] Subject: [hlcoders] Flashlight oddity Date: Wed, 26 Oct 2005 21:03:27 -0400 -- [ Picked text/plain from multipart/alternative ] I noticed an oddity involving the flashlight. I've been working on a flashlight weapon similar to the one in Doom 3 for a mod that I'm a part of. It's an actual flashlight which can be swung at enemies like a club. So far I've had no trouble attaching the effect to the viewmodel and getting the baton behavior smoothed out, but I'm having a problem with the flashlight beam itself. When the player swings the flashlight the beam goes down and out of sight along with the model just as it should. However, midway through the animation another beam appears to project from the back end of the flashlight model onto whatever happens to be in front of the player. It's a very noticeable glitch, especially in smaller areas. I took a look around and found that my flashlight effect was not the only one to act in this manner. The airboat does the exact same thing when the headlamp is on, and the dynamic lamp in garrys mod does it as well. I've linked to a garrys mod screen demonstrating the effect (it's exactly the same problem I'm having, but for reasons of clarity I captured it in there). Any ideas? Seeing the same problem pop up in the standard HL2 material and in garrys mod has slightly worrying implications. I'd really appreciate any help.
