Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Howard, are they the only lights you have used? I've had a bugger of a time with lighting so far.

ok it's easy


create two cogs that are instances of each other. Then make sure that the "teeth" of the cogs will mesh properly as the turn. Then make one a passive rigid body (this is the one that will turn the others) and the other as a active rigid body. Then place nail constraints in the centre of each of them. Now key the passive one to turn around and the other should turn based on the other one


you can then duplicate and add more cogs as needed.

Take a look at the mb file. It starts to freak out after a little while and it will take some tweaking but the basic idea is there.

Pure_Morning- you are the man!! I will check out the file when I get home tonight, that was so nice of you to do! I really appreciate it user added image

3Demon- I agree with you that it looks like a doll house or something... I think maybe because the gears are so big? any suggestions? maybe if I add some smaller stuff in there it will work itself out (i hope!)

schmick - I usually only use 3 lights, I try to keep it simple so I dont get overwhelmed. however that last render was with GIJoe user added image

it's cool mate, I think it would look really cool to have them all turning it's fairly easy to pull off but it may require a bit of tweaking on your cogs... good luck user added image

lol I dont know anything that does. I tried to write a cloth simulation and that would run stable for a while and then go absolutley bloody nuts. It's all about numerical instability as far as I recall! user added image

Some students on the same education as I tried this as their masters project. They claim it isn't impossible and what I saw at their presentation, it worked like a charm Meqon their company

They aren't rich by any means, they are just a small upstart (got their MSc this year). They are pretty young, I don't know exactly but around 23-26 I would guess (based on the avg. age of graduates here).

Sorry howard! =)

pure_morning: they should, they are really nice guys too, and they have secured some business deals. I just hope people buy their stuff, I know I would.
