get mess triangle when set mesh transparent

[zheng1038]

Hi, can anybody help me?
I want to set mesh transparent, using the following code:

Code: Select all

 
node->setMaterialFlag(EMF_BLEND_OPERATION, true);
smgr->getMeshManipulator()->setVertexColorAlpha(((IAnimatedMeshSceneNode*)node)->getMesh(), 100);
 

however, when I deform mesh and the mesh was covered by itself, I will get the a lot of triangles in the covering part. like

Any suggestion? Thank you so much.

You didn't give permission for others to watch those images.

But transparency sorting is per node, not per polygon (which would be too slow). So for those cases you have split your model.
