Hose animation problem... HOW TO START

#1

Hello guys!

HELP is NEEDED. I wish to make hydraulic hoses to my new excavator model. I figure out how to make tread crawling with excavator motion. To simplify digging animation boom, arm and bucket motion will be controled by null rotation via cyclist plug-in. I know ho to do this but stuck with hydraulic hoses.

This is my excavator http://youtu.be/W7KT_eerdyc Check out video.

Hard to say but I don`t even know where to start. Thing is this.

Example. Hose should be attached to boom on one end and arm hoist on the other. It have to bend and keep is lenght with motion and stay attached on both ends. Any not complicated idea how to do this?

I don’t know if this will help you, but Worley has HOSER as part of the Taft collection of LW plugins. For only $49… it’s a steal. I bought it when it was $199! :slight_smile:

Well

I actually used Taft and its work impressive, except one thing. Hose is strech, in this model in NOT necessary property. Does any one know is this effect can be turn off some how and allow "hose" to keep its lenght?

In the manual, it says:

"The behavior of the tube can be further modified with Hoser’s Base Stiffness and Anchor Stiffness controls. A higher Stiffness value makes that end of the tube less flexible. A stiff tube makes stiffer, larger, arcs in the tube when it’s bent. Low stiffness is like a rubber band which simply stretches and contracts instead of arcing.

A setting of 0% for both Base and Anchor Stiffness is especially useful. This makes the tube behave like a taut rubber band, always stretching in a straight line between the base and anchor points."

I don’t know if that helps, but Worley may have a more updated manual for download.

I did check it… Didn`t change too much, at least not streching

Honestly I haven’t used Hoser. But looking at the video, the fist part look perfect and (to me) acts like a hose should. The second part I can see that the far section seems to stretch while the section close to where it bends doesn’t seem to. I don’t think it looks that bad at all, and unless you’ll be doing close-ups of the area it probably won’t be noticeable. The only other method I can think of is what Worley suggested in the manual that Hoser was made to replace - a bone chain.

I would recommend going to the Newtek forum and asking the question there - plenty of LW people there. :slight_smile:
