Hey gang!

Can I create a custom mask in Qlab 5? I'm projecting onto a very irregular surface and I would like to fine-tune a mask to remove the floor and ceiling. I can remove them with Warp but that (no duh) warps the image. How do I mask out the floor and ceiling without making a bunch of mask images?

All the best!

Create a Grayscale image as a jpg or png and drop it into the mask well of your surface (QLab4) or stage (QLab 5)

White areas, show black areas mask.

You can create the mask in a drawing program as described here:
