Hi, im currently having trouble using the explode by material / attach by material function. I had been using these function with no trouble before and suddenly it stopped working and merges my material and figures into different figures and even dissapears others. I had been using these workflow for some time now but lately its just not working. I previously import my model from sketchup and then convert to corona renderer. I would appreciate it if somone had some info as to what could be making this happen. 

I would happily provide more information if someone asks for it. 

sorry for my bad grammar, english is not first language. Thank You

At the moment, I am unable to use the explode by material/attach by material feature. Until today, I was able to use these features without a hitch, but now they're not just inoperable, but also combine my data and figures, making some of them disappear entirely. I've used this process for a while, but recently it hasn't been functioning properly.
