I’ll just leave this here.. something like this would be great to add some depth to large medium distance buildings..
Is something like this technically possible for an engine like Corona?
That would be really cool. As far as my understanding goes, that should be totally possible if Corona would support OSL - something that is requested for a long time now. I think that V2 would be a perfect release for OSL support to finally happen :]
This would save so much time when doing exteriors.
Omg yes ! implement this feature 
bump with interest 9000 
Would be great indeed! This tech is heavily used in real-time projects! It’s called parallax mapping
please, don’t forget this feature idea
It could be very useful in many cases
(fake windows, fake ceiling holes/light/wallplugs etc etc…)
This is now possible with the integration of OSL in Max 2019, see Zap’s post over at cgtalk here:

Will play with that as soon that Corona is release for 3ds Max 2019
Corona for 3ds max 2019 is already there: https://forum.corona-renderer.com/ Corona Renderer 1.7 for 3ds Max (Hotfix 4) released!
Now go and play :]
Yep, 1.7.4 with 3ds Max 2019 support is already out.
There’s no daily build for 3ds Max 2019 yet, but it should be out in a few hours
But OSL should work with 1.7.4 too, isn’t?
Well, at least the basic stuff we tested did work in 1.7.4
very specific shader now doable with OSL, so closing this down
