 Hi,what is the best method to check if two materials are the same (I need to write my own "RemoveDuplicateMaterials" function). Which Parameters are used for this? Thank you!!

Anybody any idea? thx!

It always tells me that it´s different. "Being the same material" is a material with the exact same settings (the name is irrelevant though, it can be different). Just the way Cineam does. 
 But from your words, I think I better recheck if I didn´t do anything wrong.Thanks, will report if the problem still exists.

 I think I've just encountered the same problem as you, but I think I have a solution.I found (as you did), that if you just iterate through all the parameters and compare them, it always says they are different. I eventually found out that if you have a 'null' GeData object, then it acts like a NaN, in that if compares false with everything including itself. Why is this relevant? Because the parameters seem to include a whole bunch of these null/NaN values! A workaround that I found that seems to work if you want to compare materials A and B is to iterate through all the parameters, and for each parameter get a GeData gA and a GeData gB. 
 Now, before checked if gA==gB, check whether gA==gA.
 If it doesn't then ignore that parameter and move on to the next one.This seems to work! Hope this helps. Cheers - Steve
