This is hi quality,hi detail 3d model with reasonable amount of polygon consider the detail that comes with it. all part are modelled phisically down to small pipe, nut, and bolt. separate by 6 part

1. 1st stage with 6 solid rocket boooter
2. BE-4 engine
3. dual configuration RL-10 engine
4. centaur upper stage
5. inter stage
6. first stage engine cover

the texture are done with regular uv unwrap and PBR image texture. some part share the same geometry therefore use overlapping uvs, the rest is non overlapping.
