How to use custom camera with 'collide with depth buffer' node?

Hello, I use the collide with depth buffer node to create collision, it works nice

now I want to make the object invisible but still enable the collision
so I duplicate the original camera, exactly using same params and position and I change the 'Camera' param in the node to 'Custom' too, but after changing collision doesn't happen any more

I use VFX binder to bind the custom camera, it seems to be binded successfully

anyone knows the correct way to use a custom camera?
or other methods to make the object invisible but still enable collision ? I think a shader graph is needed here though

 

Well, I found the solution is that
you need to switch the camera's space in the blackboard from ‘L’ to 'W' by clicking the ‘L’ by default

 

Hey, I am dealing with how to collide with depth buffer too, I want to know how can you bind the camera since I found there is no option for the camera at VFX Property Binder script.

 

He used HDRP Camera option in HDRP category

 

Is there any other way to do that without create/duplicate main camera?
I mean auto create depth buffer from the settings of camera position, rotation, etc.
It looks like vfx graph allows that, but it doesn't work.
