Field Force with Vertex Map

[MaverickMongoose]

Hi Dr Sassi,

Is it possible to use vertex maps with the Field Force?

I've made a growing round logo animation in a vertex map and I want some rocks to be attracted to the yellow part as it grows. I put the vertex field into the Field Force but no matter what I try it has no effect. If I put a spline or an object in there instead of the vertex map it works fine.

Heres my file, any ideas? https://we.tl/t-gpQg6TIRQ4

Also the FREEZE modifier in fields is the most frustrating thing ever, constantly breaks and needs to be readded - the clear and freeze buttons seem to do nothing as well which you would think would easily reset the Freeze, am I doing it wrong?

Do you know if its possible to grow the freeze from nothing? Im using a spherical field but I dont want it to start straight away, but I cant seem to grow from nothing.

Thanks again!

Hi MaverickMongoose,

I'm not aware that a Vertex Map can provide a direction for the Force Field object. What direction would have a Vertex map with all points set to the same value?

I would use it in the Fields tab and in the Object tab, setting an object that allows for providing any directional information, such as a Linear Field or the Volume Object with added object(s) and set to Vector.

(In your file: You have Vector information inside the Vertex Map> Fields, but when you open the Hierarchy, the Direction Indicator [the arrow] is not given to the Sphere).

Great, if I just make the Field Force a negative value instead, it kinda does what I want. Thanks for that!

Thanks for the feedback, MaverickMongoose.

I'm glad you found what you needed.

My best wishes for your project.
