Irrlicht Engine

What is this DXMeshViewer and how can I get it?

I disabled the lighting and now the meshes show up white. I don't know how to tell Irrlicht to use the texture/materials that are already in the .x file. Can I do that? Or do I have to create the texture like in the Hello World example, using a bmp, jpeg, etc?

I am using Blender and have been able to export the .blend files to .x files. I have also been able to use them with the Irrlicht engine. The problem is, they only show up as black shapes when I run my program. How can I use the textures/materials that I used in Blender?
