Well, I just learned how to use unity this past month, I can't imagine it would be more difficult to learn Unreal as well. :)
But yes, I do want to explore that platform as well to see which would work better for this type of application. A long term goal would be to have an application that can directly link to a program such as SolidWorks and dynamically pull the current model into the VR application. (Very long term goal)
Is there a particular reason you want to see this in Unreal? Might help to motivate me to look into that platform quicker.
