What licenses apply to golf simulators?

We are developing a golf simulator. The golf simulator is divided into software (game) and hardware (sensor). We sell software hardware together when we sell it.
When we try to develop our golf simulator software into an Unreal engine
What license can we use?

You are certainly welcome to use the EULA. But in that case, the royalty applies to the combination of the software and the hardware. You may wish to inquire into a custom license for custom negotiated terms.

If you use an eula license, is 5% of your total revenue talking about game and hardware inclusions?We do not accept software prices because the sensor cost is high.What should I do?

I recommend reaching out to inquire about custom engine licensing in the link I posted above.

thank you~
