Change Case to all Material Parameters Values

Good morning,

I am trying to change the case to all my material parameters values and I am not sure if we are able to do that in one run or whether I need to select parameter by parameter.
I’ve tried doing this (see image) but obviously as I have 442 materials and 17919 parameters values Dynamo is not able to recognize it.

Any help?

Thank you

hi @jmariper,

can you list all your material parameters? or can you provide a sample file? it would be very helpful.
