Node Transparency

[Kuzy]

Hello,

I would like to show several nodes based on the same mesh with a certain transparency.
The following code works, but affects all nodes at once, because I change the mesh to create the transparency:

Code: Select all

 
node->setMaterialType(video::EMT_TRANSPARENT_VERTEX_ALPHA);
IMesh* mesh = node->getMesh();  
    
    for(u32 i=0; i<mesh->getMeshBufferCount(); i++)
    {
        scene::IMeshBuffer* buffer = mesh->getMeshBuffer(i);        
        video::S3DVertex* vertex = (video::S3DVertex*)buffer->getVertices();
        for(u32 j=0; j<buffer->getVertexCount(); j++)
        {
            vertex[j].Color = video::SColor(transparencyValue,vertex[j].Color.getRed(),vertex[j].Color.getGreen(),vertex[j].Color.getBlue());
        }
    }
 

I would like to show each node with it's "own" transparency value. How would I achieve this?

Well, meshes are shared by nodes. So changing mesh would affect all the nodes.
To change that per node you should probably use material settings. But afaik proper looking transparency is hard to achieve.
