How do I set a Geometry Collection to be dynamic with the Fields system?

I have a question about the field system.

I’m looking for a way to create a function equivalent to the Set Dynamic State function in a field system.

Set Dynamic State requires you to specify a collection, which makes it inconvenient to apply the same field across multiple collections.

There is a Dynamic State item in Add Transient Field, but no matter what I enter, nothing changes.

Thank you in advance.

You should be able to set the dynamic state from a field using an integer type of field
I recommend looking at the master field sample asset provided

This tutorial and the following video tutorials should provide enough information

I hope this helps

Thank you for your reply.

I have checked these tutorials, but Master Field has too many functions, so I set it up using an actor derived from Field System Actor.

I’ve checked the ranges in the debug box and set the fields, but no matter where I put the field it overrides the dynamic state for the whole collection.

All anchors are deleted, but other collections outside the field range are not affected, so it does not seem to be a mistake in the range setting.

The field is 5cm square and I’ve used it with Strain and Linear Force, but they either affect the entire collection or nothing.

I’m very confused and can’t pinpoint the cause.

Hi

Typical fields problem involve not setting up the culling field properly
You say that other geometry collections are not affected, so that may not be it , but i still encourage you to check that

Other things to check is the resolution of the field as well

I copied most of the main parts from the master field, so the culling field is included.

I don’t know about the resolution.When I search, the only thing that comes up is Distance Field resolution.I haven’t changed anything so at least it’s still the default.
