I was working on a project on Hitfilm Pro 2017's Mocha plugin. I had multiple track layers ready for camera solving. I selected all of them, and clicked on the dropdown menu for the option "Matte Layer". When I click on this, Hitfilm immediately crashes. I've tried four times already but with the same results. This does not happen if you only select one track layer, however.
Or does it crash? Please leave a comment if this happens to you as well.
