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!
