The first example crashed my computer :X..first time I've ever gotten BSOD on my pc

Probably cause my computers shitty.. Anyways great effects, too bad I can't use them though (damn you x64 vista on 2gb ram and Nvidia Gforce 7100!:evil: )

I don't understand how I could use XEffect with my other shaders.
I have a reflexion/refraction shader on a mesh, and I'm trying to use XEffect, just with bloom post proc effect at the moment (lighting later...).
The scene does not render while the mesh node with shader is visible. When I use node->setVisible(false); the scene is rendered correctly with bloom.

The line which make Xeffect render fail is:

Code: Select all

myNode->setMaterialType(E_MATERIAL_TYPE(myShader));

How could I use my shader with XEffect?

It shouldn't fail for this reason alone, you can use your own shaders alongside XEffects. Perhaps the extra pass for rendering the reflections/refractions is screwing something up?

Here is the additional code used with the shader:

Code: Select all

 RTTTex = driver->addRenderTargetTexture(core::dimension2d<u32>(512,512));
		ITexture* NormMap = driver->getTexture("glassNormalMap.png");
		myNode->setMaterialTexture(0, RTTTex);
		myNode->setMaterialTexture(1, NormMap);
s32 GlassMat = gpu->addHighLevelShaderMaterialFromFiles("GlassV.glsl","main",EVST_VS_2_0,"GlassP.glsl","main",EPST_PS_2_0,this);
myNode->setMaterialType(E_MATERIAL_TYPE(GlassMat));
TintColour = SColorf(1.0f,1.0f,1.0f,1.0f);



//later in the same class:

OnSetConstants(irr::video::IMaterialRendererServices *services, irr::s32 userData) {
  

     core::matrix4 WorldMat = driver->getTransform(ETS_WORLD);
     services->setVertexShaderConstant("mWorld", WorldMat.pointer(), 16);

     core::vector3df CamPos = device->getSceneManager()->getActiveCamera()->getPosition();
     services->setVertexShaderConstant("CamPos", &CamPos.X, 4);

     float AlphaAdjust = 1.0f;

     if(ForceAlphaTo0) AlphaAdjust = 0.0f;

     services->setVertexShaderConstant("AlphaAdjust", &AlphaAdjust, 1);

     int TexAddress = 0;
     services->setPixelShaderConstant("RTTexture", (float*)(&TexAddress), 1);
     int TexAddress2 = 1;
     services->setPixelShaderConstant("NormalMap", (float*)(&TexAddress2), 1);

    
     services->setPixelShaderConstant("TintColour", (float*)(&TintColour.r), 4);
}

And here is how the shader is used, juste before calling the "update" methode from XEffect to render the scene:

Code: Select all


    driver->setRenderTarget(RTTTex, true, true,       SColor(255,100,100,200));
     myNode->setVisible(false);
     ForceAlphaTo0 = true;
     
     device->getSceneManager()->drawAll();
     
     
     ForceAlphaTo0 = false;
     driver->setRenderTarget(0, true, true, SColor(255,100,100,200));
     myNode->setVisible(true);

//and update now the whole scene:
effect->update();

it's really funny:

if I do:

Code: Select all

myNode->setMaterialTexture(0, NormMap);
myNode->setMaterialTexture(1, RTTTex);

it's working, however if I do:

Code: Select all

myNode->setMaterialTexture(1, NormMap);
myNode->setMaterialTexture(0, RTTTex);

It's not working

Well... I'm ok with it if it's working, but it's a little strange, maybe a bug?.
I just switched texture layer ID in the shader constants for now.

Now, I have a couple of questions about XEffect :

-Is it possible to cast shadow from a node, 'receive' shadows froms other nodes, but don't 'receive' shadows from the same node himself? (no selfshadow)
Oh well, my mistake... There is the CAST shadow mode availlable (with RECEIVE and BOTH) I just had to put it in the addShadow call.

-Is there an issue against bad shadows on nodes borders? It seems it's pixelized.

-How could I render lines ? using draw3DLine from the driver is not working, nothing is displayed.
I think I can't render lines with draw3DLine from the driver because it's drawing it with OpenGl instantantanly, then XEffect render the whole scene to a quad and display the quad hiding lines. Using a node can resolve this problem as it's rendered to the quad by XEffect, so as I wanted to draw a grid, I used the forum grid scene node and it's working, but it's not really cool if you want to draw single lines.

Thank you very much.

hey thrrrrrrrrrrrrrrr

I have similar problems to gingerheadman but with funny issues at run time

in openGL example 1 crashes on function getShadowMapTexture with an Access Violation at this line using irrlicht 6.1 or 7.1

I have tried and tried to get this working with my project but to no prevail

i can get the Post Processor features working but not the shadows themselves it seems that my version of irrlicht does not think PS or VS 3.0 does not exist

everytime i load my project the Console Window says this

HLSL vertex shader compilation failed
error X3506 unrecognized compiler target 'vs_3_0'

then when i try and set a shadow an error like this shows

Error setting the float array for HLSL variable

and my console just fills up with this error

and no shadow is cast and effect is very dim...

I Do have PS and VS support as i am using dual 9600 Ge-Force Cards so any help for this would be greatly appreciated

Note - I am using Irrlicht 1.4 as any one thats newer Crashes my project - i have tried earlier versions of your XEffects Project but with the exact same issues - is there some special version of irrlicht i need to use or something else please help would be great

Code: Select all

	effect->addShadowLight(SShadowLight(vector3df(PC->getPosition().X,PC->getPosition().Y,PC->getPosition().Z-10), vector3df(5, 0, 5), SColor(0, 255, 0, 0), 20.0f, 60.0f, 60.0f * DEGTORAD));
	effect->addEffectToNode(PC,EET_PHONG); 
	effect->addShadowToNode(PC,EFT_8PCF);

My Shadow code which brings this error

You can try changing all references to VS_3_0 to VS_2_0 in EffectHandler.cpp (But keep PS_3_0 the same).

easy mate
dont quite get your answer as your code in effecthandler.cpp seems to switch between the two dependant upon GPU features ala

Code: Select all

video::E_VERTEX_SHADER_TYPE VertexLevel = driver->queryFeature(video::EVDF_VERTEX_SHADER_3_0) ? EVST_VS_3_0 : EVST_VS_2_0;
	video::E_PIXEL_SHADER_TYPE PixelLevel = driver->queryFeature(video::EVDF_PIXEL_SHADER_3_0) ? EPST_PS_3_0 : EPST_PS_2_0;

I have vertex/pixel shader 2 and your code picks the correct one "2" but example 1 still crashes with "Access Violation" on

Code: Select all

shadowMapTexture = driver->addRenderTargetTexture(dimension2du(resolution, resolution),
			shadowMapName, use32BitDepth ? ECF_G32R32F : ECF_G16R16F);

with the same HLSL compile errors at the start (complaining about pixel shader 3) see above

please help, the previous version of XEffects ran inside of my project and on the same GPU

thanks
Rob

I switched from irr 1.6 to 1.7.1
Surprise! When I use XEffect all my textures are flipped!
This reminds me of a bug I submited about the draw2DImage function, with a kind of matrix which wasn't initialized good...
It's exactly the same problems, draw2DImage function draw my images flipped

(only if I use XEffect)

Do you have this problem with irr 1.7?
If not, I'll try do put a standalone cpp file in bug report threads...
If I use smgr->drawAll instead of Xeffect->update, images are displayed correctly.

The probleme is appering when using post proc effect like bloom.
I'm using OPEN GL driver.

This probleme is not under SOFTWARE driver.

The line of XEffect which's inverting every textures is :

Line 449 - EffectHandler.cpp

Code: Select all

driver->setRenderTarget(i >= PostProcessingRoutinesSize - 1 ?
				outputTarget : ScreenQuad.rt[int(Alter)], true, true, ClearColour);

Fixed this problem :

Add at the end of update function in EffectHandler.h this line:

Code: Select all

driver->setMaterial(irr::video::SMaterial());

Just a brief question, can one mesh, terrain, whatever be lit by both ILightSceneNode from irrlicht and a shadowlight from xeffects at the same time?

Posted: **Sun Mar 07, 2010 7:38 pm**

I'm getting the same problems with the pixel and vertex shader 3.0 version. I've tried changing both of them, but I get a blank orange screen and the console says "Error setting HLSL float array" or something of the like. I know my graphics card supports vs and ps 3.0, and I remember it working before. I'm using 1.7.1 if that helps. How long will it be before the new shadow system in irrlicht? If it isn't too long I'll just wait for that instead.

Posted: **Fri Mar 12, 2010 9:32 am**

Anyone got luck compiling/launching this goodie on linux?

For me it compiles with a load of warnings and results a SIGSEV fragmentation fault.. Most of the warnings are from XEffects files.

Posted: **Sun Mar 14, 2010 8:09 am**

There seem to be a whole lot of technical problems cropping up lately. Did NVidia introduce something nasty in their graphics drivers? I'll get back to you guys after some testing. Don't mind the warnings, probably some non-explicit type cast stuff.

Now I had a look at the console output. It contains mostly FBO incomplete/error.

P.S. my video card is NVidia GF 7600 GS.
