>> I compiled my program with and without MaterialMerge graph op and I
dumped the the same scene using these two versions of my application. When I
did not use the graphop, all the materials shows up on the geometries the
way its supposed to. But when I used the graphop some of the materials
didnot show up on the same geometry.

have materials in collada and in my application.
