Hello. Unfortunately, it is currently not possible to change the collider parameters at runtime. We have not implemented this as an API because there have been no requests for it. However, we will add the API in the next version as we believe this feature is absolutely necessary. If you are in a hurry, you can temporarily change the source code as follows. If you change the Radius, Length, etc. of a collider, you need to call the contents of the OnValidate() function of each collider. This can be found in MagicaSphereCollider.cs / MagicaCapsulCollider.cs / MagicaPlaneCollider.cs. As an example, in MagicaSphereCollider.cs, this is the part shown in the image. However, OnValidate() cannot be called as-is, so you need to prepare a public function that copies its contents and call it. We apologize for the inconvenience, but please try this method for a while.
