Hello everybody,
I try to do a physical animation about a candle flame in front of an open window. The flame should change its direction if the candle moves upward. So I put a force field in front of the candle’s flame and the flame direction changes into room. But when I move the flame upward the flame doesn’t change its direction although it is outside the force field. I tried to duplicate the force field, rotate it 180 degrees but nothing happened.
To show what I mean I put a rendered movie to this thread too.
Would be great if someone could solve my problems.
But when I move the flame upward the flame doesn’t change its direction although it is outside the force field.
It will be still be affected by the force since the wind force object just indicates the direction of the force, the force is not actually coming from the force object itself. An object can be in front of or behind the force object and it will make no difference. You can use a collision object and the force ‘Absorption’ option to block a force
Hello Richard,
thank you for your answer. In my case I don’t know which dimensions or shape the collision object may have. Is it possible to use a hidden plane for such function?
Could you give me an example for using such a combination?
As I replied the posting before I would need a short example about tho collision object and the Absorbtion field. Maybe this is a stupid question, but using force fields seems not to be so easy as I thought.
See the example blend file containing 3 cloth simulation objects and a wind force.
There is a plane in front of each cloth sim. Only the middle plane has an Absorption value of 100%, the other two planes have no absorption value. Therefore only the middle plane absorbs all the wind force so the middle cloth does not blow in the wind. If you move the plane during the simulation you’ll see the wind take effect since there will be nothing absorbing it
