Hi,
I am developing plugin for material.
It can copy & paste Texture to other Texture.
It seems to be working well.
But, material's thumbnail couldn't be updated.
Src Code is like this.
 
BaseContainer* pContainer = pMat->GetDataInstance();
  GeData src_data = pContainer->GetData( MATERIAL_COLOR_SHADER );
  GeData target_data = pContainer->GetData( MATERIAL_REFLECTION_SHADER );
  src_data.CopyData( &target_data, NULL );
  pContainer->SetData( MATERIAL_REFLECTION_SHADER, target_data );
  pMat->Update( TRUE, TRUE );
 
Could you give me some advice?
