Issue with renaming the parameters of a material

Hi, I’ve found an issue in 4.11 with renaming the parameter of a material: after the operation, all the instances have the renamed parameter reset to its default value. Currently I have hundreds of material instances and some parameters to rename; I cannot afford to memorize all the values of the parameter and set them again manually.

Is there a workaround to this specific issue that I can take advantage of? Thanks.

You can just build a blueprint function library and make accessors (setters and getters) for that parameter. So the parameter will keep its incorrect name but to all designers they’ll be able to call a function on the instance which will change the value.
