    Hey guys, since there are not much Excavators in the Unity Asset Store, i started to create one.

    Progress:
    Blocking Basic Shapes:

    Details to the Arm & Shovel:

    The Cabin:

    Bit from the Back:


    What i'd like to know is:
    1. Should i animate things like the arm & shovel already to the extremes?
    2. Or is it better to script all of that stuff? Like look-at's for the hydraulics and such.
    Please don't be shy and give me some feedback.

    Cheers OctoMan

    You could animate it but it might be easier to code the mechanics. It depends on what you're comfortable with I suppose. If you're taking the coding route, you basically only have to make sure all pivot points are in the right place and you can add any model and it'll work. I wouldn't worry too much about polycount as long as you have the right mechanics, you can always choose a different model.

    I'm able to rig and animate it fully. The pivots will be at the correct positions, same with all needed dummys and such. I am also able to animate the hydraulic's using lookat in unity codewise, but i don't know what is more useful for those who would buy that asset.

    Can you stop an animation at any point? Like on release of a button and idle on that particular animation point?

    It seems it's better to code the lookat for the pistons, since i can't export constrains. This works so far, but i have a problem with the shovel rig.

    Since i can't use IK Chains i need to figure how i can make this setup work in unity. Feel free to help me out ;).

    A quick rendering of the current state. I found out how i can animate everything, and will set it up like it. I believe i will also add a non animated version for those people who want to play around more with physics.

    Shall i keep cables and such that low poly? Tell me what you think!

    Hell Octoman

    Great job, i m trying to animate a bulldozer, no problem to me to rig it in 3dsmax, how do you have managed animation (if you don'y used physics) in unity ? play and reverse frame by frame ?

    I couldn't use physics for the shovel rigg. So yeah i pre-animated and used frame animation also reversed. Problem was basicly pausing the animation on whatever frame the animation currently was. Also preventing looping.

    need some help with this setup, i have the camera inside the cockpit and making the camera a child of the excavator works fine, but when rotating the cockpit the camera doesnt rotate, i have tried rotating the camera when the keys are pressed but that didnt work correctly any advice, i am new to unity.

    I just tried it. You need to go deeper into the Hierarchy until you reach Cylinder001(bad nameing convention sorry).
    Make the Camera Child of it(Cylinder001) so when the top part rotates, the cam will follow.
