Hi!!
First of all! Amazing work on the plugin, thank you very much for the effort!!
It will be very nice if we can have a matte option that can just hold out the scene; Right now the matte option serves as a shadow catcher, so is not possible to just hold out because my alpha channel will have the shadow information also and there will be some overhead because of the shadow computation over the matte object. So currently my approach is to do two renders, one with the shadow catcher and another with the shadows turn off for my original object to get a clean alpha channel and with the hold out.
Thank you!
