I'm wondering if it's possible layer a Construct project with a transparent background above a separate browser canvas/process. I have a colleague who has a simulation running in Mapbox, which is running in an iFrame, and I want to layer my Construct project on top of it. I've found references in past forum posts about setting the overall background of a project to be transparent, but so far we've been unsuccessful. Every option we've tried results in a project with an opaque background. Is there a solution here?
