    Sorry for this newbie question - I have search and found a few threads but not answering this particular question.

    In script I have created one Mesh() with a few polys, in unity I have a couple of materials I made.
    Now I want to assign these materials to each polygon in script. Actually two tris per material.
    So what is the way of assigning which polys goes to which material in script?

    (would prefer not splitting up into one meshobject per material :) )

    Thanks people!

    What you need is to configure your mesh to have two 'submeshes' - one per material - by setting mesh.submeshCount and then using the SetTriangles() function (instead of just mesh.triangles = ...) to set the triangle indices for each individual submesh.

    so submeshes would get the same indexorder as material a presume?

    Yep. Just set renderer.materials / renderer.sharedMaterials with the array of materials you want to use.
