I would like to simulate a star exploding into a nova, ie
I have a quick smoke where the density is keyframed, emitting smoke from a sphere for few frames only. I need a force that pushes this smoke in every directions, uniformly. Vorticity, noise, texture, collisions, high definition smoke, etc will do the job of modelizing the shape as it goes and offer nice details. I do not want to use a mesh.
But it doesn't seem to exist any force field that acts like a sphere, attracting or repulsing everything from a single point and uniformly. This is very easy programmatically so I surely missed something and I hope someone will point me to the correct feature ! Otherwise I'll have to learn a bit of python I guess.
Wind only pushes smoke in a single direction. I can make it a cone-wind, with an angle of 90° and both 2 directions, I can only get :
I can put it to sphere of course, this is another frame but same :
At last what approaches the most my needs is the "force" force field, in "sphere" mode, but it is absolutely not uniform :
I have to mention I also tried to expand an invisible sphere used as a collider, however I cannot use this then to get the vorticity, smoke effects precisely, that I am looking for.
Any idea ?
