Debugging Native OpenGL Plugin

Hey all,

I've been playing around with this repo: https://bitbucket.org/Unity-Technol...lugin/PluginSource/source/RenderingPlugin.cpp
that shows how to make your OpenGL code interact with unity and its rendering pipeline.

My biggest problem with it is debugging. couldn't find a simple way to print out to unity console/breakpoint in the cpp dll/ etc.
Does anyone have any suggestions?
Thanks in advance!
