Bug with ShapeBase::startFade()?

I am using ShapeBase::startFade() to smoothly add/remove objects from the scene.

However, this does not work with the opengl2d3d wrapper, with applied lighting pack.
Objects are popping in and out instantly, without any fade.

In TSMesh::setMaterial() an OpenGL blending is setup, using the overrideFadeValue of the object, which get's modulated during the fade duration.

if( overrideFadeVal < 1.0f && dglDoesSupportTextureEnvCombine() )
   {
   ...
      ColorF curColor;
      glGetFloatv( GL_FOG_COLOR, (GLfloat*)&curColor );
      curColor.alpha = overrideFadeVal;
      ...
      
      glTexEnvfv(GL_TEXTURE_ENV, GL_TEXTURE_ENV_COLOR, curColor);
      
      glTexEnvi(GL_TEXTURE_ENV,GL_TEXTURE_ENV_MODE,GL_COMBINE_EXT);
      glTexEnvi(GL_TEXTURE_ENV,GL_COMBINE_ALPHA_EXT,GL_REPLACE);
      glTexEnvi(GL_TEXTURE_ENV,GL_SOURCE0_ALPHA_EXT,GL_CONSTANT_EXT);
      glTexEnvi(GL_TEXTURE_ENV,GL_OPERAND0_ALPHA_EXT,GL_SRC_ALPHA);
   ...
   }

In the wrapper function for glTexEnvf the lighting pack executes:

if(((int)param) == GL_CONSTANT_EXT)
		g.m_d3ddev->SetRenderState(D3DRENDERSTATE_TEXTUREFACTOR, g.m_envcolor);

As far as I know, this is not enough.

To make this work a call to

SetTextureStageState(0,D3DTSS_ALPHAARG1,D3DTA_TFACTOR);

also needs to be issued, to make that state use the supplied alpha color.

The lighting pack defines a lot of StateBlocks that are switched/enabled depending on the rendering settings. However, there is no state block, that uses D3DTA_TFACTOR as an alpha blend arg and obviously no code, that switches to this block.

Tried to figure this out on my own, but the state management in this dll is quite complicated.

John, could you please verify this and in case you find a solution, provide me with a fix.
This issue is one of a few issues, that needs to be fixed for our upcoming release.
