Okay, all of you who are getting the beta to work along side the official Carrara 8 install:
If you intend to open any of your existing saves from 8.1 for use in 8.5
BE SURE to SAVE using a UNIQUE NAME!!!
It’s actually very cool, that 8.5 beta converts all of your texture maps to “Fast MipMap” filtering. However, once it does this - re-opening the file in 8.1 will give you a blank filter for each an every portion of each and every shader that uses an image file - simply because “Fast MipMap” doesn’t exist in 8.1
If this happens to you, you’ll have to go through each shader that contains and image file and change the image filtering back to “Sampling”.
This is not a bad thing - but you should know that before saving existing files using 8.5
What I did was to copy my entire browser from “My Documents > DAZ3D > Carrara 8” to “My Documents > DAZ3D > Carrara 8.5” so that each application has its own copy of all of my saved files - but that’s because I save everything to the browser via the above My Documents structure. If you save another way, just copy it over to a new location so you can use it safely - or simply get used to saving all of your 8.5 files in a way that you can tell the difference.
Hope this makes sense - just trying to save you from unnecessary time consumption
