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!!

I tried to browse through each container ID and check if they are the same on both materials, but that doesn´t work (either if I check the returned GeData with the compare operator == or if I really check the values of each GeData).
Anybody any idea?
thx!

How do you mean? Why doesn't checking all values work? How would you define "being the same material"?

I don´t know why it doesn´t work, but it doesn´t. 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.

Hi Katachi,
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
