NWShader

[peachykeen]

I've been working on a little project for about a week now, and when I asked about it over at the official NWN boards, a few people suggested I bring the subject up here as it may be related or I may get suggestions. I'm new to the NWN modding community (hi! ), so (not knowing where to go) I did what they said.

The project, in essence, hooks OpenGL for Neverwinter Nights and injects its own calls to the video hardware. How I have it set up, I can add post-processing effects (fullscreen shaders) after NWN has drawn the game scene. This allows for a lot of modern effects, such as depth of field, bloom, HDR, and their ilk.
It doesn't actually add functions or features to the game, but sure has the ability to make it look pretty.

I have a SF project page set up (here), with a single example shot at the moment:
https://sourceforge.net/dbimage.php?id=251280
The effect is a heavy color-burn type deal, just to be obvious for debugging purposes. When the framework is smoothed out and stabilized, more useful effects will be possible.

Any questions or comments are welcome, especially tips about how best to handle this. I have a working tech demo (works on my system, at least ), and am basically trying to figure out where to go and who to talk to in order to get this project going within the NWN community.

Thanks, peachy

Would this be a possible way to deal with the increasingly flaky driver support from nVidia and ATI?

It may help with that. NWShader uses/needs a more recent version of OpenGL than NWN itself, and anything NWN tries to do with the graphics can be translated to work better on new drivers. As long as the problems can be pinned down, I can look into wrapping and fixing them (depending on what the issue is exactly).

Just uploaded a new copy of this, with some more screenshots:

It runs a simple bloom shader at the moment, but more effects can be used.

I tried and it makes the game unplayable for me. I get an FPS around 1-5 and everything in the area is white-untextured and if I enable any of the shader options the game simply crashes on-start. Here is the log:

From the log, there isn't anything going terribly wrong. That issue sound more like a shader failing and breaking things. I need to check, I don't think the GUI supports it for Epsilon, but make sure per-pixel lighting is off. That's not working yet and can cause the problem you're mentioning.
Do you actually see geometry, just without any textures? And if you have shaders, what error does it give when it crashes or what does the log say?

I've put in a bunch of fixes and tweaks and am getting ready to release an update, so you might want to just hold off and try this new one, it has a lot of stuff fixed.
