Hello all, I've modeled a feather using the one in the content browser as a guide, and now would like to animate it as if it were falling. What I've tried so far was create a spline of a path then had my feather align to spline, then animated the rotation. This potentially could work, but was wondering if anyone knew of a better and more realistic way to make the model of the feather fall. Thanks for any input.

That is a great tutorial. That helped me get on the right path. There's one thing that is kind of frusturating about C4D, and maybe it's the same with other 3d apps but I'm not sure. To have any dynamics or anything affect your model it needs to be editable. I can understand why it needs to be like this, but I just wish that it could use things that weren't converted to editable (ie. hair/feather items, extruded/sweep/loft, etc...). Anyway that's a tangent, but is still kind of frusturating. Thanks for the repl though.

hi
you can animate what you want without convert to polygons :)
here is the tip: just make a copy of your object, in this exemple i'll use the sphere, because like you know a sphere primitive is an equation, this is why you can see a perfect sphere, now if you convert it to editable object you can't make it perfect without increasing subdivisions!
so if you want to make animation with a perfect sphere and dynamics, just make a copy of the perfect sphere, now convert the copy to editable. and make the perfect sphere (not editable) as child of the editable, now clic on the visibility option of the editable sphere to hide it from render (make it red) and in the visibility option of the perfect sphere (the child) make it green to force it to appear when rendering! now just make your simulation! the result is that when the simulation will be calculated with the editable sphere, so the animation will be recoreded with editable sphere information, but in render you'll see the perfect sphere :thumbsup:
with this tip you can make complexe simulation, just make a lowpoly as actor and the real object as a star that appears on TV :scream:
hope you understand my bad englsih.

That's a clever workaround, and definitely speeds up my calculation times. Thanks for that workflow idea.

hi
dont forget to hide the open gl view (i dont know if it's called like this, it's the place you can se object and simulation) and you can increase your speed calculation to 50%! that's because it will be done in background and no graphic data will be calculated in order to be shown(it's my suggestion, i dont know if it's real)
this tip is usefed when caching (calculating cache, or baking solver) :thumbsup:
