Not sure if this is an option, I can't find anything in the setting. I'm fairly new migrating back to Corona from VRay after a while with the latter.
I have a few objects with displacment textures, when I have a Corona displacment modifier on top, they work fine, taking the map from the material. When I turn off this modifier it interprets the displacment via the Max scene units (meters in this case, so the object blows up)
I VRay there was an option to interpret the displacment via a set figure (1x scene unit by default I think) which could be turned off so that displacment only happened if a Displacment modifier was present and turned on.
Is there similar in Corona?
The reason I ask is I'm trying to debug some displcment that is looking wrong on an object, so wanted to just see with/without by flicking the modifier on and off.
