Unforunately it's not possible to paint alpha, nor 3D Coat is capable of displaying cutouts or semi-transparent surfaces. You can cheat your way out by (for example) painting a layer in black and white and exporting it as colour for further processing in photoshop.

There was a hack someone found a few years ago that allowed you to do that, but I'm not sure where that is located. I believe it was a video on youtube.

 

 

For what it's worth, I use two different workflows depending on where my stuff is going. For rendering, I either paint a black a white image for masking, or, I will just paint around where I want the holes, and make sure you have paint on all the other layers you want, and then just turn off layer 0. Layer 0 has the "base" mesh information, and when turned off, allows you to export alpha channels in all of your textures. I use the latter for exporting to Unreal.

That's a good tip, Javis. Thanks for sharing it with us. :)
