GLSL Shaders

[sfan5]

For me, I get it all red. (Using sfan's build posted above.) Windows x86 XP with intel GMA

Don't use DirectX

[PilzAdam]

Vanessa's issue with water is definitely caused by Irrlicht 1.8
Current tree (i made many updates yesterday) is working under 1.7.3

Actually thats wrong, I use Irrlicht 1.7.3 and all water is grey. It also says something about "reflection.png missing" (or similiar).

[Inocudom]

... DirectX is on, innit?

There aren't any Direct X shaders currently.

First lets have OpenGL up n runnin.

I heard that there are ways that OpenGL shaders can be converted to Direct X shaders. As you said, of course, the OpenGL shaders do have to be stable first.

One issue is that Direct X 9 is the highest version Irrlicht can use for the time being.

I guess you mean pull and rebuild?

It pleases me greatly to see you supporting RealBadAngel's shaders, PilzAdam.

The new water shaders are very impressive, but may still be a little glitchy. Water that is in caves still has grayish coloration from time to time. Another thing I noticed is that lava also gets the water shaders, but ends up looking like water in the process.

The parallax mapping is working now, but the effect doesn't appear to be 3D from some viewing angles. Xonotic, Red Eclipse, and Sauerbraten have parallax mapping in them, so they can provide inspiration if it is needed. Calinou is involved in the communities of those games, so he might be of assistance.

I can tell that good progress is being made with the shaders. I know that the end result will be impressive.

[RealBadAngel]

I have updated first post with all the aviable config settings.

Issue with parallax not working perfectly is that we dont have properly calculated tangent.
I do have the code to calculate it in the engine, but theres no way to pass it to shaders.
Theres no way in irrlicht to use GLSL shaders attribute or to pass uniform sampler buffers.

That does not sound good. Why would Irrlicht not have such a feature?

Those are not errors but your OpenGL, I guess youre using open drivers.
Im not sure if i can make all the code run with it but i will try.
Whats your OpenGL version?

I'm pretty sure that are errors..

intel GMA

You will not be able to run shaders whatsoever.

Sorry bud.

They run in FlightGear, but they cause tons of lag. I was just gonna check out what they looked like.

For me, I get it all red. (Using sfan's build posted above.) Windows x86 XP with intel GMA

Don't use DirectX

I'm not using it (I guess). Well, minetest reports that my OpenGL version is 2.0 so maybe I'm running OpenGL. Again, I don't think sfan made a build with DirectX.

[Inocudom]

With PilzAdam's latest build of RealBadAngel's shaders branch, I was able to record a video of the shaders. The video is of somewhat low quality, but the shaders are visible.

[cHyper]

are there any shaders planed for AMD video cards?

[VanessaE]

In theory they should work with any video card, but they don't work for me. I assumed it was an incompatibility with my OpenGL version (4.3.12614), as RBA develops on an older OpenGL (2.2 or something) and AMD video.

okay after i read your message i was looking whats the difference between the two computers. after a update for the newest OpenGL on the big one, i dont get this error anymore. so looks like this is something with the OpenGL drivers which cause the problem.

[RealBadAngel]

Looks like on one end im using something that is not supported by older drivers and at the very same time things that were removed or altered in new ones.
Thats pretty weird :)

I think i removed most of the "errors" reported by sfan5, i think.
One remains for sure is texelFetch, will see what i can do about it.

Please do note if you see everything red, shaders were not compiled (due to errors) and are not workin at all.
Also if reporting errors, please do paste not only the message that shader is not working, but the lines around sayin what were the errors...

[RealBadAngel]

My "fork" is updated with brand new calculations of tangent space.
Finally parallax mapping is looking as it should from any angle.
One problem left is kinda texture sliding, which is natural for it.
But i propably may have an idea how to solve it...

Meanwhile some new shots:

Without/Bump/Bump+Parallax mode 1





and some reworked HDX texture too:

[Inocudom]

I wish there was a way that this branch could be merged with proller's next branch. Maybe PilzAdam's version of this branch could be?

Why do your bricks look all glassy with the bump mapping turned on? They don't look glassy in normal mode.

[RealBadAngel]

Why do your bricks look all glassy with the bump mapping turned on? They don't look glassy in normal mode.

Mainly to show the difference. Also, CrazyBump's default settings creates pretty "strong" bumpmaps ;)

I don't know if it is relevant or if it will help out at all, but just trying. =)

The windows debug console gave me a hard time. I however, managed to extract the following

So, the GLSL shaders did not compile after all...

I don't know if it is relevant or if it will help out at all, but just trying. =)

Please tell me your version of OpenGL (You can see it when game starts within first lines)
Also most of those errors are already fixed in my branch (youre using older build)

[RealBadAngel]

Here comes windows build with up to date shaders.
All the errors reported in solids shaders should be gone.
Please let me know if it works for you.

http://realbadangel.pl/minetest/shaders/minetest_shaders_11-10.zip
Build comes with Haven texture pack to test the changes with, minetest_game and config file.

I tested the build that you made, RealBadAngel. I tested the tweaks you made to parallax mapping, and I can see that they are working better now. I can't really notice the parallax mapping effect on the plank and bookcase nodes, but it is noticeable on the dirt, sandstone brick, desert sand, brick, and sandstone nodes.

It appears that there is a red/purple discoloration in the fog towards the right side of the screen while underwater, and the shaders don't work on moving water (still water works fine.) Lava still does look like water at the moment.
