What do I need to display customSceneNode with texture?

Im trying to display TEXTURED custom mesh... but its black, either lighting is disabled or enabled. And i got one light in my scene with radius 1000 when its on 0,0,50 and mesh is at 0,0,0. Can somebody tell me what I missed? Texture's loaded properly, i chek'd in log.

Code: Select all

	Material.Lighting = false;
	Material.MaterialType= video::E_MATERIAL_TYPE::EMT_SOLID;
	Material.setTexture(0,driver->getTexture(name));

Code: Select all

	driver->setMaterial(Material);
	driver->drawIndexedTriangleList(Vertices[0], Vertices.size(), &indices[0],triangles);

Probably wrong normals. Lighting calculation depends on it. And of course missing texture coords as well.
Or winding order, since you're using cutsom render methods. Why not just create a mesh from your vertices and add it to a scene node?

I cannot just load mesh, im working on my own scene node.
Well, I checked everything again, and im almost sure that the textures coords, normals, and textures are loaded properly.

Can you help me get it to work without lighting?

EDIT: Now I found out really strange thing!! I made lil test with vertex colors (still without lighting).
First I seted color of each vertex to blue and commented the "setTexture" line. Mesh was blue.
Then I uncommented the "setTexture" line. And mesh appeared textured?! However still blue'ed... so I setted each of colors of each vertex to 100... and it fixed it!! So now everything works, but idk why...

Why can't u just load a mesh?
The scenenode is only there to place the mesh animate and call the render method. Drawing itsef is done by IVideoDriver.
You can for example draw meshbuffers with IVideoDriver::drawMeshBuffer (const scene::IMeshBuffer *mb).

I cant just load a mesh because I need to have acces to vertices/indices every frame.

So what?
You can load the mesh and then access the indices and vertices through the mesh buffers of the mesh. Where is the problem ?

Oh yes, but its even easier to operate with them inside custom scene node class.

EDIT: Now my model works with lighting! I still dont know why, why I had to set all three colors to 255 to let it works...

vertx color is modulated with the texture color. You should always start with full bright vertex colors.
