(Solved)alpha vertex looks very bad.

[REDDemon]

this is the code. the cube is showd partially correct and partially full of "black nois"

Code: Select all

scene::IMesh* cube = smgr->addCubeSceneNode(300)->getMesh();		 
scene::ISceneNode *node = smgr->addMeshSceneNode(cube,0,-1,vector3df(0,0,0)) ;
smgr->getMeshManipulator()->setVertexColorAlpha(cube, 100);
node->setMaterialTexture(0, device->getVideoDriver()->getTexture("test_alphablend/water.jpg"));
node->setMaterialType(video::EMT_TRANSPARENT_VERTEX_ALPHA );
noder->setMaterialFlag(video::EMF_LIGHTING,false);

EDIT:
i solved just creating a cube with blender and importing it as a mesh from file.

Next time i will try to get the mesh from a node and erase the node

Well it looks like you're adding 2 cubes, and there's zfighting between the two. Try moving one or scaling one down.

[REDDemon]

already done. without succes.
I tried to move both the mesh and the cube.

I tried also to drop the cube (there is not an available remove).
but the problem persist.

Maybe it wasn't studied to work this way.

Hm, that looks like what commonly happens when two planes share the exact same position.
