irrCg v0.8 (Initial) - CgFX (Texture States, MultiPass etc.)

Nadro · Post by **Nadro** » Mon Aug 11, 2008 12:35 pm

IrrCg doesn't support *.fx files. Yes, You can use it as is, but You have to define in shader callback some parameters: matViewProjection, ModelColor, ModelColor2 and entry points: vs_main, ps_main. You can do it via IrrCg material file.

and I included the files necessary, i'm using IrrCg 0.7 which i think is compiled with 1.4.1, right?

Nadro · Post by **Nadro** » Mon Aug 11, 2008 5:10 pm

You have to also linking cgGL.lib, because it IrrCg is compile with OpenGL support (in v0.8 I will add option to disable / enable OpenGL support similar for Direct3D9). You have got probably wrong Multi Threaded flag selected - LIBCMTD.lib errors.

Well, i'm using the Debug DLL and i'm already excluding the libs, now i got these link errors:

There aren't IrrCg errors. With IrrCg all is ok, compiler log doesn't show problems with Irrlicht and IrrCg. Errors are cause by wrong Multi Threaded options in Your project (Static/Dynamic DLL). You can try use static Multi Threaded runtime. Other problem is cause by Havoc engine linking.

Gman3344 · Post by **Gman3344** » Tue Aug 12, 2008 5:11 am

Ok, i got it to compile with everything how ever something strange happens, The app tries to run but then it gets an access violation. it points to this line:

Code: Select all



strlen.asm:
mov     eax,dword ptr [ecx]     ; read 4 bytes

My code to load the material:

		GPU = new IrrCg::ICgProgrammingServices(this->Device);

		if(GPU)
		{
			GUI->addMessageBox(L"Shaders are working",L"Yay for shaders!",true,EMBF_OK);
		} 
	}
	
	s32 Color = GPU->addCgShaderMaterialFromMaterialFile("Shaders//Red.xml",MCB);
	
	if(!HavokInit.Initialize_Havok())
	{
		return 1;
	}

	this->LoadLevel();
	this->LoadPlayerMesh();
	
	if(Color)
	{
		Player_Mesh_Node->setMaterialType((E_MATERIAL_TYPE)Color);
	}

My material code:

<?xml version = "1.0"?>

<Program Vertex = "Effect1.fx" Pixel="Effect.fx"/>
<EntryPointName Vertex = "vs_main" Pixel = "ps_man"/>
<DirectXProfile Vertex = "vs_2_0" Pixel= "ps_2_0"/>

<Callback>
	<ParameterWVMatrix Program="Vertex" Name = "matViewProjection" Transform = "MATRIX_IDENTITY"/>
	
	<Parameter4f Program="Vertex" Name = "ModelColor" X = "1.0" Y = "0.0" Z = "0.0" W = "1.0"/>
<CallBack/>

I hope you know what is wrong.......

Nadro · Post by **Nadro** » Tue Aug 12, 2008 8:55 am

For the shader programs from Your previous post this material file is wrong. This is improved material:

Code: Select all

<?xml version = "1.0"?>

<Program Vertex = "Effect.fx" Pixel="Effect.fx"/>
<EntryPointName Vertex = "vs_main" Pixel = "ps_main"/>
<DirectXProfile Vertex = "vs_2_0" Pixel= "ps_2_0"/>

<Callback>
   <ParameterWVMatrix Program="Vertex" Name = "matViewProjection" Transform = "MATRIX_IDENTITY"/>
   
   <Parameter4f Program="Pixel" Name = "ModelColor" X = "1.0" Y = "0.0" Z = "0.0" W = "1.0"/>
   <Parameter4f Program="Pixel" Name = "ModelColor2" X = "1.0" Y = "1.0" Z = "0.0" W = "1.0"/>
<CallBack/>

You have to check parameters <Program> and <EntryPointName>

Copied and pasted the material and still get access violation......wonder why? damn it. I'm using Irrlicht because of everything it has, other wise i'd have to program all the features of Irrlicht my self, just wish i knew why this was happening..

Gman3344 · Post by **Gman3344** » Tue Aug 12, 2008 4:22 pm

I just tried to use pure DirectX with Irrlicht to load the shader and it worked, problem is that if i use Scene manager->draw all, it'll render all the meshes with that shader. another problem is since i'm using DirectX matrices it locks the mesh to the camera, so basically, with the FPS camera, you'll have your mesh follow the camera if you just rend that one mesh. Well, at least I got FX files into Irrlicht.

Nadro · Post by **Nadro** » Tue Aug 12, 2008 4:35 pm

I don't know what is wrong, but on 100% this is cause by Your programming error. You have to check Your program code, maybe it has some issue eg. wrong path in material file etc.

Gman3344 · Post by **Gman3344** » Tue Aug 12, 2008 4:50 pm

The effect is in the same folder as the xml, so i don't know. Unless i have to make 3 matrices in my shader file as i had to do that in another file i used that i got to work with DirectX like this:

Code: Select all



float4x4 View : View;
float4x4 Projection : Projection;
float4x4 World : World;

that's the 3 matrices DX needs to set up the file good. I think for FX files you need three different matrices for it to work good, so i don't know, but it's something that i got FX files to "work" in Irrlicht......better then nothing I guess. Hey, do you have MSN? or AIM?

Gman3344 · Post by **Gman3344** » Tue Aug 12, 2008 8:05 pm

Ok, i managed to load the material into another project and it didn't give me any problems about that but for some reason, the Pixel Shader Color isn't being set.

for some reason, the .xml file isn't being loaded.... I put it in a folder with the effect from Render monkey.....and nothing....Damn it.....
[/code]

Nadro · Post by **Nadro** » Wed Aug 13, 2008 11:13 pm

No I don't have MSN/AIM. If material file isn't loaded You have got wrong path for it in Your code. Try build Your demo with IrrCg material file example, You will be see where You have got error.

dlangdev · Post by **dlangdev** » Thu Sep 04, 2008 10:41 pm

OK, I'm downloading latest version and will begin testing it on 1.4.1.

Is IrrCg_v0_7 compatible with 1.4.1?

Nadro · Post by **Nadro** » Fri Sep 05, 2008 2:24 pm

Yes, it works properly with Irrlicht 1.4.1, but lib in archive was compiled with Irrlicht 1.4, so You need rebuild IrrCg with Irrlicht 1.4.1
