Hi,
as you can see in this discussion, there are good reasons to make 3DSMax crop function work along side the VFB render region:
On another note, making the the texture render mask more intuitive would also be very benifitial. Like not having to draw a black&white mask in Photoshop but to be able to just draw directly in the VFB!
You are doing great work as always!
Thank you for listening!
