Cinemachine ClearShot Camera and Trigger collider volumes

Hello,

I've run into an issue for which I'm wondering whether there's a reasonable workaround:

In our game, our tree trunks have regular physics colliders; however, the top part of the tree (i.e. the leaves and small branches) is made up of one or more spherical colliders marked as Triggers - physics objects don't *bounce off* the leaves or stop short, but when they enter that trigger we do various things to slow them down (and play audio, etc.).

It seems that CinemachineCollider (used by ClearShotCamera) uses QueryTriggerInteraction.Ignore in all of the raycasts it uses to determine whether a target is obscured/occluded. Because of this, ClearShot will generally not choose cameras that are obscured by a tree trunk, but will choose a camera that is obscured by the leaves of a tree - which is not ideal.

The only workaround I can think of is to add a duplicate set of colliders to all of the tree tops, exactly the same size as the trigger collider for the leaves, that none of our other physics layers collide with but which is not a Trigger, and then include it in the layer mask for the CinemachineCollider. However, this is a pretty big change - our environment has a huge number of trees, which means we'd probably be introducing hundreds or thousands of additional colliders into our scene, which potentially has other implications.

Is there a way to tell a particular CinemachineCollider not to ignore trigger colliders, at least for certain layers?

 

Hi Gregory, thanks for the suggestion, I'll give that a try.
