Quote - You can use 1.2, just make sure that you don't have displacement maps. You can have as many versions of Lux installed on your machine as you want. Install 1.2 in its own directory and switch to it whenever you want. If you need to render something with displacement use 1.1.

The Output tab of Reality is where you select which version of Lux to use. 

Cheers.

 

So you are saying all I need to do is go through all the maps in my reality and remove all displacement maps? Is there anything that would depend on them?
