Probleme mit Specularlighting

[Ishildur]

Hallo ich bins noch mal! Ich bin gerade dabei, meine Engine zu portieren und bin dabei auf ein weiteres Problem gestossen, auf das ich partout keine Lösung finde:

Und zwar funktioniert nun das Specularlighting nicht mehr?

Das ist der Code:

void KB_Engine::__handleModelRendering(KB_Control *pCon){
 // declare and init local variables
 KB_ModelManager *pMgrMdl = pCon->getModelManager();
 KB_Model        *pMdlCur = 0x00;
 KB_Component    *pComCur = 0x00;

 // start a loop for walking each model inside the list
 while(pMdlCur = pMgrMdl->getNextModel()){
  // continue if the current model isn't visible
  if(!pMdlCur->isVisible()) continue;

  // get the resource of the current model
  KB_ModelResource *pRscMdl = pMdlCur->getModelResource();

  // get the resources of the effect - layers
  if(pMdlCur->isEffectLayerResourceDefined(KB_EL_PRM))
   this->p3DDev->SetTexture(1,pMdlCur->getEffectLayerResource(KB_EL_PRM)->p3DTex);
  if(pMdlCur->isEffectLayerResourceDefined(KB_EL_SEC))
   this->p3DDev->SetTexture(2,pMdlCur->getEffectLayerResource(KB_EL_SEC)->p3DTex);

  // assign the worldmatrices of the model and the surfaces
this->p3DDev->SetTransform(D3DTS_WORLD,pMdlCur->getModelTransform()->getWorldMatrix());   
this->p3DDev->SetTransform(D3DTS_TEXTURE0,pMdlCur->getModelSurfaceTransform()->getWorldMatrix());
this->p3DDev->SetTransform(D3DTS_TEXTURE1,pMdlCur->getEffectLayerSurfaceTransform(KB_EL_PRM)->getWorldMatrix());
this->p3DDev->SetTransform(D3DTS_TEXTURE2,pMdlCur->getEffectLayerSurfaceTransform(KB_EL_SEC)->getWorldMatrix());

  // create temporary material - struct
  D3DMATERIAL9 matTmp = {0};

  // a loop for rendering each subset
  for(DWORD i=0;i<pRscMdl->numMat;i++){
   // copy the material of the current subset to the temporary material buffer
   CopyMemory(&matTmp,&pRscMdl->pArrMat[i],sizeof(D3DMATERIAL9));

   // multiply each color component of the diffuse color by the parametric color
   KB_Color *pClrDif = pMdlCur->getDiffuseColor();
   matTmp.Diffuse.a *= pClrDif->getAlphaAsFloat();
   matTmp.Diffuse.r *= pClrDif->getRedAsFloat();
   matTmp.Diffuse.g *= pClrDif->getGreenAsFloat();
   matTmp.Diffuse.b *= pClrDif->getBlueAsFloat();

   // copy each color component of the ambient color from the diffuse color
   matTmp.Ambient.a = matTmp.Diffuse.a;
	  matTmp.Ambient.r = matTmp.Diffuse.r;
	  matTmp.Ambient.g = matTmp.Diffuse.g;
	  matTmp.Ambient.b = matTmp.Diffuse.b;

   // copy the emissive color
   KB_Color *pClrEmm = &KB_Color(0xff000000);//pMdlCur->getEmissiveColor();
   matTmp.Emissive.a = pClrEmm->getAlphaAsFloat();
   matTmp.Emissive.r = pClrEmm->getRedAsFloat();
   matTmp.Emissive.g = pClrEmm->getGreenAsFloat();
   matTmp.Emissive.b = pClrEmm->getBlueAsFloat();

   // set the specular - color
   matTmp.Power = 1000.0f;//pMdlCur->getSpecularPower();
   this->p3DDev->SetRenderState(D3DRS_SPECULARMATERIALSOURCE,D3DMCS_MATERIAL);
   this->p3DDev->SetRenderState(D3DRS_SPECULARENABLE,TRUE);

   // set the material and the texture
   this->p3DDev->SetMaterial(&matTmp);
   this->p3DDev->SetTexture(0,pRscMdl->ppArrTex[i]);

   // draw the current subset
   pRscMdl->p3DMsh->DrawSubset(i);

   this->inf.__setNumberOfRenderedVertices(pRscMdl->p3DMsh->GetNumVertices(),KB_OM_REL);
  }

  // unset the textures
  this->p3DDev->SetTexture(1,0x00);
  this->p3DDev->SetTexture(2,0x00);
 }

 // a loop for walking each component
 while(KB_Component *pComCur = pCon->getNextComponent()){
  // call this method for each sub - component if it is enabled
  if(pComCur->isVisible()) this->__handleModelRendering(pComCur);
 }
}
// --------------------------------------------------------------------------------------------

Du setzt keine Specular-Farbe im D3DMATERIAL9...

Scheisse, du hast Recht! Ich IDIOT!!! Manchmal ist programmieren wie die Rechtschreibung, der Autor kanns hundertmal durchlesen und sieht den offensichtlichen Fehler nicht.. :p

Danke dir, dass du dir die Mühe gemacht hast, das Teil durchzulesen!!!

Gruss Ishildur
