fae_alba Posted February 9, 2014 Share Posted February 9, 2014 Papa Bear is going fishing in a few days, but he needs some fish to catch before he can. I've modeled up the fish, and am at the point of coming up with a rig that will best give the impression of a swimming fish. I started out with a simple backbone rig, adding some dynamic constraints to help simulate the swimming. The movie below is the result. While i kind of like the result, the fish swims more like a dolphin than your run of the mill trout. But for the life of me, I can't seem to suss out the best approach. Ideas? The rig: The result: (no keyframes applied, the result is simply the dynamic constraints at work) swim_test.mov Quote Link to comment Share on other sites More sharing options...
markw Posted February 9, 2014 Share Posted February 9, 2014 Did you use a sideways motion on the fish's tail? It looks more like you used a vertical motion? Also have you turned 'Gravity' OFF in the dynamic constraints. That might also be adding to the up and down motion. Have a look at the Action contained in the attached Project.

Mark, the motion is strictly from the dynamic constraints...dropped the fish in the chor and viola, the tail wags. I'll have a look at the gravity setting, that sounds promising.

Hash Fellow robcat2075 Posted February 9, 2014 Hash Fellow Share Posted February 9, 2014 In my collection of tuts there's something on animating a decaying pendulum that could also be used for the side-to-side motion of a fish, ifyou leave out the decay part.

fae_alba Posted February 9, 2014 Author Share Posted February 9, 2014 Ok, so I tinkered with the force settings in the chor...switched y from 100% to 0 and x from 0 to 100% and get the following result. Getting there. Going to read up on Roberts' tuts now to see what sage advice he has on pendulums. swimtest0.mov Quote Link to comment Share on other sites More sharing options...
