Hi,
Not sure why the light is not showing in viewport. I think it's because I'm creating a light, then turning on target, then moving the light to another layer and forgetting to move the target. This might be a Max bug and not corona. See attachments. Is this a bug? It's probably a button I clicked and don't remember.
I also had similar issues in the past (that may have been fixed) with corona camera targets resetting to zero and was never was sure if it's my workflow, something to do with switching between DOF override and target or a Max bug.
Thank you!
