i am new to Material Maker, i downloaded the 1.4b2, but i get a pink preview, the examples are working fine, but anything i do or any material i downloaded from the website, is not working, same pink preview, i searched the internet, but i didn't find any solution.
If you're new to Material Maker, please use 1.3.
1.4 releases are beta and are not ready for production yet (this is mentioned at the top of the project description).
Your issue is weird, though, could you please tell me which OS and which GPU you are using? Thanks a lot in advance!
Oh, and please don't hesitate to join the Discord, we have an awesome community. ;)
