Irrlicht Engine

I think I will put aside this problem for now and work on something else. It's just getting ridiculous. If I could use quads, it would be so simple. The only thing I could come up with is to store all 4 vertex-colors of a square inside the primitive's provoking vertex (which I only just heard about....

Ok, after reading a bit about shader attribute variables, I decided there is no way to change the way interpolation between vertices is done. So the color I get to use inside the fragment shader will always be triangle-interpolated and it's impossible to modify the weighting. For example, the right-...

Your patch... Is it part of some other Irrlicht branch or how do I get it? Can you give me a quick overview about what Irrlicht versions there are? Because I only ever used the "standard" version. I think doing some fake quad interpolation on triangles inside the vertex-shader probably isn...

All I ever did inside fragment shaders was to use either global or vertex-interpolated values. No idea how I'd do per-pixel lighting. I googled it, but didn't find anything enlightening... So... I would need a light map for every surface I guess? In a large voxel world that would easily make hundred...

Let's assume for a moment I never said anything about quads ^^
Would you have any suggestion how I can make the transitions in the second picture look like in the first?

I use vertex colors as some kind of static lighting, so I can raycast to each vertex only when changes occured in the world and have shadows without any performance loss. I know it doesn't look very pretty, but with some smoothing later on, I think it will suit my needs. I suppose the problem is, I ...

Thanks a lot!

Does anyone have good links to free texture (particularly seamless tile-like ground textures) and sound collections that may be used in a commercial project?

Thanks cuteAlien, like I had guessed. Works well.

I did, but it doesn't say how I would use the material's set ambient color, for example, inside the shader.

I would set it as a constant, if I knew how to get to it...

I guess I will need to use onSetMaterial and store the material-variables inside the derived callback class.

How?...

I've only used the IShaderConstantSetCallBack::OnSetConstants function so far.

I tried it again with color transparency and ambient color. I had forgotten to enable lighting, because it's usually on by default (except for skyboxes...).

Works the way I wanted now. Thanks anyway.

I want to gradually set transparency for my skybox. Behind it there's only the scene-color. I tried to get to the vertices by casting to IMeshSceneNode, but it doesn't work. Otherwise I could have used vertex-transparency. Using color-transparency together with the material's ambient color doesn't s...

I don't even know what it is :/

I think I might once again use a dirty workaround and use the vertex normal-components for other purposes, but in the long run, being able to define my own vertices might be handy.

You can check how to define custom vertex type in following example: http://sourceforge.net/p/irrlicht/code/HEAD/tree/branches/shader-pipeline/examples/29.HardwareSkinning/main.cpp So, after a year I finally looked into that example, because I'm at a point now, where 2TexCoord-vertices won't do any...
