View Full Version : Dynamics - Draping bed cover?

I have spent ages trying to drape a bed cover (plane) over a bed using Dynamics. I have attached the tags and attached a soft body spring tag to my cover and a rigid body dynamic tag to my matress.

Cover: Collision set to full; Static Coeff 60%, Dynamic Coeff 50%
Matress: No mass; Collision set to full;

I have played around with the options but my cover just keeps falling right through the bed. I have attached gravity in my solver object. Can anyone explain where I'm going wrong please?:hmm:

Surely dynamics can be used for something like this?

Is everything inside the solver object and are all objects made editable?

HI,
you must reinitialize the scene after EVERY change of settings
:annoyed:

Here is a cloth drop file in did in CD4XL7.3.3

http://66.70.166.29/promo/ClothonCube.zip

the solver has been turned off andthe keyframes of the
animation have been baked to the timeline.
but you are welcome to "reinitialize" the solver to reverse engineer
its settings.
however any recalculation of the simulation will take some time
depending on you CPU power etc.

heres a rendered animation of the cloth simulation

Good luck

What settings do you have in your Solver object? specifically which integration methods and how many samples and sub samples.

Thanks guys. All the objects are in the solver and they are all editable. I have tried re initialising but no joy. My Solver object settings are:

Main Tab: Start = 0F;
Stop = 150F;
Integration Method = Runge-Kutta;
Oversampling = 16 (Sub sampling greyed out)

Details Tab: Energy loss = 10%;
Collision Eps = 10;
Baking frame step =1;
Layer 8;
Rest Speed not checked;

I have looked at the example but just can't get the cloth to stay on the bed.:annoyed:
