You can do it with a bone chain and a spline ik. I'm sure there are dozen of tuts on the web, but here's the page i used for animating a chainsaw once. http://developer.reallusion.com/whitepaper/Tank_Tracks/ Now if you want a dynamic setup with the chain adapting to the terrain, that's another story.
So far I've figured out how to set up a series of tank track objects running along a spline representing the path of tracks on my tank model. The positioning of the tracks at each point, however, is often completely incorrect as to what it should look like in real life. The problems naturally occur around sharp bends in…
Ya, I did spend some time wondering about this... even thinking for a moment that it could have been possible it was some kind of alternating pattern but realizing that was impossible. Still, lining up the sections with the blueprint makes it seem like they're pretty much around the right size if not exact. Doesn't seem to…
I´m going to push this thread because i had to do a chain for a client :) . My setup is basically a curve with a number of nulls placed evenly. These nulls have a curve constraint which gets manipulated by an expression + offset value to control the movement with a control object. Then i created a second set of nulls.…
Just tried centering the pivot and though it's still not perfect, it's probably good enough for most purposes and you wouldn't really notice anything if it was in motion or at a small distance. Good call. Will still try the bone method and compare results.
Compared to the reference image your track elements are too long. In your blueprint the tracks are made out of two different shapes. One track piece with "spikes" and one without. When you create your tracks this way you will get a better deformation. You could also try it with a centered pivot maybe this gives you a…
