I would expect False, True, True.
Let’s have a look at the first one. You print out the boolean value rayhit.isEmpty(). So getting a hit will print ‘False’.

You set the custom filter expression like this

self.scene.setFilterConstant0(PhysxGroupsMask.allOff())
    self.scene.setFilterConstant1(PhysxGroupsMask.allOff())
    self.scene.setFilterOps(op0 = self.scene.FOOr, 
                            op1 = self.scene.FOOr,
                            op2 = self.scene.FOAnd)
    self.scene.setFilterBool(True)

From the NVIDIA docs:

Now, using your setting, you have:

(G0 or 0000...) and (G1 or 0000...) = True

For the box you set GROUPSMASK1, which is ‘100000000000…’,
and for the ray you also set GROUPSMAKS1. Inserting these values for G0 and G1 gives:

(1000.. or 0000...) and (1000... or 0000...) = True

or

true and true = true

This is true, so your ray scores a hit for the box. And raycase.isEmpty() will return ‘False’
This is what I get when running your script.
