Normal Maps / Depth Maps - Testers Needed! V1.0

Download Here.
This is a playable demo of normalmaps and depthmaps in Spring, using GLSL. It isn't a game, it's tech demo.
This has two GLSL shader implementations based on failure to compile, which, depending on whether you have nicer hardware than mine, you'll see one or the other. I don't have a switcher built yet, and probably won't bother, since this is just a tech demo.
The first is Kloot's code, as intended. The second, which just does normalmaps, and lacks self-shadows (I keep meaning to write a new shader just for that task, but I've been a little short on time) is my cut-down version, which is still a lot prettier than Spring's default ARB shader.
99% of the hard work and mental perspiration on this project was Kloot's. As you folks probably know, I did some early work on this topic, but Kloot got Spring working correctly with the features, and I've been waiting until P.U.R.E. calmed down a bit to finally get it in front of people. Since that doesn't seem to be happening and I'm still really busy... I decided that today I'd quit procrastinating and release this test for people to evaluate, and proceed from there.
I want testing results from folks. Screenshots and infologs- if it works, show us that it's working, and please let me know what hardware. If it breaks terribly, please let me know that, too, with infologs and screens.
This is a pretty important feature for Spring, in terms of looks, so the more testing that can be done, the better it'll get, and the better it gets, the better Spring games can look. Please help test this.

Hrmm. Great start
Try unzipping it to SDD, and deleting my lighting Gadget, just to make sure that that isn't the problem.
Trying to think if anything else could possibly causing it to just plain crash... I just tested with fresh ArchiveCache, and it's not a dependency issue or something silly like that, it still works just fine. Weird. I guess that's why we're testing

Problem was with running it through spring.exe, works fine through the lobby (was crashing after countdown/beofre comm spawn like bruce)

Bizarre.
So... it fails on countdown, but doesn't fail if you just go through the Lobby?
WTF? That's just plain weird. Probably isn't the Gadget's fault, then. Probably.

remove most consts, ati doesn't like them.

I'll see about fixing that in my lighting shader immediately.

Version 2. Tried to fix the lighting shader by addressing the "inherent conversion" bug by making the operation explicit. Please re-download and test, imbazcek, I'd like to know if the lighting works on ATi finally.
Put the lighting shader in and active. I'll go look at Kloot's GLSL next.

it works on geforce 2 but of course without fancy gfx.
at least it doesnt crash.

it claims "no shader support" but my card does have support for GLSL shaders and i've seen it do normal maps.
it doesn't crash however which is nice

It looks like it compiled the GLSL for the lighting shader. Can you test whether that works, with the latest build? I'll see about removing that upvalue.

seems it's a problem with gl.CreateShader not existing in spring, so i don't think it's actually a problem with your code.
sorry, would probably help if i enabled LuaShaders support in settings =p
looks great!
(although way too slow for my hardware)

Have you enabled LuaShaders in SpringSettings?
Also... version 3 is up... I added disco lighting, for lulz.
Let's see... any ATi users seeing my lights now? Pretty please, you stupid drivers?
Maybe somebody who couldn't see normalmaps can now (fixed yet-another "implicit conversion" bug in the normalmap shader)?

Really? How bad?
Those are high-poly spheres (about 8000 triangles for the both of them), so this is somewhat of a stress test anyhow.

with the unit off screen i get ~60fps, with it on screen i get ~30fps
with 14 of them i get ~12fps
so could be worse i guess. normal maps means you can get away with a lower polycount so for a game with a small amount of units it could be okay.

14 of them is 96K triangles per pass. That's really not that terrible. Typical scene in P.U.R.E. is maybe half that.

Ok, so i decided to give this a whirl. Seems to work ok performance wise. Got playable fps with 100 of them on screen, and my card is low end (9500gt)
I think they look pretty decent, nothing amazing. but normal map support like this will be cool.
