Syphon Out: How to preserve transparency for 'Main Output'

#1

It seems that any transparency in layers is lost when VDMX sends the ‘Main Output’ to a Syphon client. (Everything is on a black background). Is there a way to preserve it?

I’ve tried many routes to fix this, but hopefully I’m missing something obvious.

Transparency is preserved in Syphon when you send individual layers, but I need to send the full composite. I tried creating a Group, but this too adds a black background.

Thanks.

I’ll spare you the explanation, but due to a subtly with the rendering engine, try switching to the GLSL composition modes (Addition.fs and VVSourceAtop.fs as a replacement for the ‘GL Over’ mode).
