Chernobyl Shaders - converting all shaders to Cg in work...

[monkeycracks]

I wish I could use shaders, they look really nice.

[krama757]

Great stuff Nadro! Keep up the awesome work....Ill try to implement these into my projects (Giving you all the credit ofcourse!)

[Nadro]

OK you can use this stuff in your project I can't currently work on next shader (and repair multi-light), because I'm finishing my Game (commercial project on Irrlicht, I add screenshot in August). If I done game I add next shader:)

[Masterhawk]

Hey guys, can anyone accord me a plastic shader in HLSL? Perhaps convert Nadro's one to HLSL? Don't know how much work it is to convert such a shader, sry.

@Nadro: great work!

@BlindSide: When do you think to release your shader-pack? Does it contain a plastic shader? Which shader will it include in general?
Hope your pack is released soon

Hey since you are good at GLSL can you convert my shadow mapping shaders from HLSL to GLSL please? I will release my own shader pack very soon in HLSL so we can work together to provide solutions for both drivers.

PS: Irrlicht already has Shadow Volumes thats what stencil shadows are...But maybe it is faster in a shader?

You can probably use ATI's http://sourceforge.net/projects/hlsl2glsl to convert most of your HLSL to GLSL.

[Masterhawk]

is there a tool to do it the other way around?

Yes I used this but for some reason it didnt work, I think it will need someone to do it manually. Also Irrlicht requires a special method for passing textures to GLSL that is different from HLSL (And im not sure what that method is haha). But I really want to switch shadow maps to open gl because:

A - In opengl (In irrlicht) you can have any resolution RTT you want, so high res shadow maps without having to change screenres.

B - In opengl (In irrlicht) you can use 24-bit depth maps.

@Masterhawk. About releasing my pack, it will hopefully be pretty soon. I had the flu for a while and I just went on a trip too so time was limited. Hopefully tomorrow or the day after I can finish it up. It has some shaders similar to plastic like phong etc. In fact there is a plastic material so I will try and add that one (Not sure what shader model it was tho..).

How?

[Masterhawk]

Hm, this shader don't work for me. First it says ' Unexpected token: "[" '. When I comment it out the shader loads correctly, but when using I cannot see my sphere and an error message occurs again and again...

error msg:

HLSL Variable to set not found: 'mLightColor'. Available variables are:
'view_position' Registers:[begin:4, count:1]
'view_proj_matrix' Registers:[begin:0, count:4]

Do I have to have a dynamic light in my scene?

[Nadro]

You must add variable in CallBack mLightColor eg:

Code: Select all

video::SColorf Color(1.0,0.9031,0.1536,1.0);
services->setVertexShaderConstant("mLightColor",reinterpret_cast<f32*>(&Color), 4);

For OpenGL my shader CallBack look that:

Code: Select all

class CGE_Shaders:public video::IShaderConstantSetCallBack
{
public:

	virtual void OnSetConstants(video::IMaterialRendererServices* services, s32 userData)
	{
		video::IVideoDriver* driver = services->getVideoDriver();

		core::vector3df Camera_Pos = device->getSceneManager()->getActiveCamera()->getAbsolutePosition();
        services->setVertexShaderConstant("Camera_Position", reinterpret_cast<f32*>(&Camera_Pos), 3);

		video::SColorf Color(1.0,0.9031,0.1536,1.0);
        services->setVertexShaderConstant("Color", reinterpret_cast<f32*>(&Color), 4);
	}
};

You needn't any Lights on the scene

[Masterhawk]

But these variables are already set in my shader callback. that's the strange thing...

my shadercallback is the one from the shader-tutorial
http://irrlicht.sourceforge.net/tut010.html

[Nadro]

I write this shader in HLSL tomorrow and I upload it

[BlindSide]

@MasterHawk. Thats not a serious error. It just means that the you have passed the shader the mLightColor variable, but the shader is not using it in its variables to output the final result. All you have to do is comment out the variable from your shader callback.

[Masterhawk]

@MasterHawk. Thats not a serious error. [...]

Hehe, not serious, huh....
When I use this shader I cannot see my sphere anymore...

I think I'll wait for Nadros rewritten HLSL shaders....
