ok, i want to use a mesh that is returned from a different engine (i plan to use irrlicht as the renderer and the other engine for the rest of the stuff) now if i wanted to do this would I just do this?
In one of the replys, someone said it was in dx format. im not sure what the difference is, i am a noob when it comes to dx, or opengl, i've just used basic engine commands up till now.

For all of your 3D/2D resource needs:
Most likely the other engines vertex format is not the same as what Irrlicht uses. You would need to create a mesh buffer of the correct type [SMeshBuffer, SMeshBufferLightMap or SMeshBufferTangents], and then push vertices and indices onto that mesh buffer, being sure to initialize the right fields of each vertex.
