It’s mentioned in the docs, though my preferred solution would have been to hide the outline when you’re actively editing the polygon collider, not this “collapse renderer component” behavior which is awkward at best.
Well, it mentions the behaviour in the Poly Collider doc, but not in the Sprite Renderer doc, so even if you thought it was caused by the Sprite renderer panel you wouldn’t find it in the docs.
My issue is that sometimes you wish to collapse panels you aren’t actively working on to keep the UI manageable. I’m new to Unity but not to programming and this behaviour runs contrary to every other dev environment I’ve worked on. In my case I was working on some animation and I collapsed the Sprite Renderer panel to keep a script panel and the Animator panel in view. All of a sudden I was unable to move my sprite around and I didn’t realize why.
Not to complain too much! So far Unity has been great to work with and is actually very intuitive.
I just had this issue and discovered that it was because I had selected the “Game” tab instead of the “Scene” tab. Made me feel like a dumb noob (which I am), but figured others might run up against this.
