I am testing trial substance painter 2018.2.1 and I am facing a problem that I did not have on previous version (2018.1.0), when I load an onder version of substance painter file the material comes pink (please see attached files) and this doesn´t happen on version 2018.1.0, even though the file is from an onder version. As can be seen on the pictures, all the other maps are fine, such as basecolor, mettal etc..except for MATERIAL. The log is transcribed below, it seems that it has something to do with error C1008: undefined variable "pbrComputeBRDF" , but I couldn´t find anything on internet to help. So, I would be glad if someone could give me a hint how to solve this problem.
Best regards,
Geraldo
PS. Below IS the log I get when trying to open an older version of substance painter file.
