So this is our light sensor unit(the blue thing) it has to move up and down and out and in so thats the reason for all the gears. But the thing is, this is just a little bit of the whole thing, so i'm going to be having a few problems.


Problems
(1) These pictures are 100,000 polygons in that object, and the exporter i use is pretty efficient with the use of polygons, and i really REALLY like the look of radiosity, i'm gonna be setting up a render farm of 5 computers if i can but i don't think that will be enoguh, so does anyone have any tips for this?

(2) Each peice is it's own object so is there a way to change the reflection on each one, because when i want to use hdri for reflections the default for the peices is 40%, and there are to many pieces to change and tweak to what i need, so how do i change a lot at once


Maybe Problems
(1) I need to learn expressions, i am planning on animating it, but i don't think i will animate the gears, just the wheels when i move it (remember, not full rover in this picture) so i was thinking i could just parent everything together (when i export it actually creates a scene with everything parented for the part of the rover i save(since i will make it in pieces)) and then use expressions to rotate the wheel

(2) This is just a thought, but since every lego is it's own object, i think at the end i will have it fall apart or blow up and have all the pieces go everywhere
