ZDoom

No, it clears the zbuffer before drawing it.

Before my fix it was drawing the weapon with coordinates in view space (eye's perspective) with the camera pointing straight ahead at (0,0,0). Now it is drawing it in world space with the camera positioned correctly in the world. Visually you can't tell the difference, but it meant that pixelpos wasn't getting the proper values it needed to project into light shadowmap space.

Quick question (not being able to check myself at the moment): by "positioning it in the world", does that mean the HUD weapon model will clip into level geometry (as seen in almost every amateur Unreal Engine 4 game)?

Good to see that this positioning hack is gone. I never liked how this was implemented because it was nearly inevitable that it'd cause problems down the line.

Thank you, glad you like the shadowmaps. :)

I managed to fix it, but it meant I had to repair some old code first. It should be working in the next nightly build.

[quote="dpJudas"]Ah, crap. Because the weapon sprite isn't drawn in its true world position the shadowmap lookup fails. :([/quote]

I take it that isn't exactly easy to correct? That's really too bad, gzdoom is pretty gorgeous right now. Once shadowmaps came out I began
to make one of the best looking mods out there, and I was looking forward to it. Besides this, bump mapping on 3d models(yes I'm aware
dynamic lights only would affect it) and shadowmaps only being used on one-sided linedefs I really cant complain at all for this port now.

Hope something can be done!

See Topic name. The Shadowmap hitting the model has all sorts of lighting issues, like the game
doesn't know exactly where the model is originating maybe?

I have an example wad all set up along with screenshots.
