I didn't code the original engine, but I have tweaked it recently to make D3D mode look prettier :) (note to self, signup with valve email address...)
I don't know enough about the win32api to be certain you can't enable the stencil buffer somehow, but you certainly can't do it via SetPixelFormat().

We? I can't imagine you were involved in coding the render engine ;) Ok, what you want to say is that there is absolutly no way to create a stencil buffer, right? *sigh* I really liked to see it and rumors going through the internet about a HL mod with shadows like in Doom 3 *g*
The stencil buffer is never enabled by the engine, in 32bpp mode we use all 32 bits to make the textures look prutty :)

A wichious circle. What happens when you launch HL with command line option -32bpp ?
Read the MSDN documentation on SetPixelFormat, you can only call it once per HDC (so you calling it a second time has no effect). You can't destroy the HDC as HL is using that to render into.

iirc you cant have a stenscil buffer with a 16bit z-buffer, you have to use a 32bit z-buffer, 24bits being for z-buffer data and the remaining 8bits are used for stencil infomation
I was sure the nehe stencil tuts had a 16bit z-buffer :/ and I still cant get it to work. There is no change in any of the values when i get windows to describe the current pixel format. Its a though its going back to the old settings >_<.... Anyone got this to work? Shimms you said it could be done O_o... how the hell.... Do I have to destroy the DC as well O_o?
g_hDC = wglGetCurrentDC(); g_hRC = wglGetCurrentContext();

wglMakeCurrent( g_hDC, NULL ); wglDeleteContext( g_hRC ); g_hRC = NULL;
pfd.cStencilBits = 1; pfd.cDepthBits = 32;
iPixelFormat = ChoosePixelFormat( g_hDC, &pfd ); SetPixelFormat( g_hDC, iPixelFormat, &pfd);
