How to set new Material to an IMeshBuffer*?

[Masterhawk]

Hi folks,
I have a simple question:

I have to change the Material for a specific mesh buffer in my mesh, but I can't find a function like "meshbuffer->setMaterial()".
How do I achieve to change the material?

Code: Select all

if(mb_idx >= 0 && mb_idx <this->getMesh()->getMeshBufferCount())
    {
        IMeshBuffer* mb = this->getMesh()->getMeshBuffer(mb_idx);
        
//SET NEW MATERIAL HERE
 
        video::S3DVertex* verts = (video::S3DVertex*)mb->getVertices();
        for(s32 v=0; v<mb->getVertexCount(); v++)
        {
            verts[v].Color = clr;
        }
    }

Thanks in advance

hi,

i would say that

Code: Select all

driver->setMaterial(Material);

should work.

well this meshbuffer is part of a huge mesh containing a huge amount of other meshbuffers.

The mesh is rendered as a scenenode in smgr->drawAll(). So I want to apply a new material to the meshbuffer structure so the material is chosen automatically in the drawAll function.

Scene node has:
http://irrlicht.sourceforge.net/docu/cl ... 4fc2ed05b2

Which returns a reference, so you can just assign your material to it like this:

Code: Select all

 
node->getMaterial(some_mesh_buffer_index) = otherMaterial;

//SET NEW MATERIAL HERE

mb->getMaterial() = somematerial;
