Corona Material Library - Glass Materials not working anymore

Hey guys,

today I’ve got a really strange issue. A lot of the glass materials out of the Material Library are not working anymore. (They did before)
I restarted the whole system also a new file but still not working correctly. Do you may know about this issue?

Same Problem with Liquids.. Really strange

Thank you very much!

My guess it’s scale issue. Did you change scene units recently? Try to increase absorption distance of the glass material and see if that helps.

Thank you so much romullus!!

I didnt change the scene units before but the absorption distance was the problem anyway.

I was going to reinstalling Corona, it’s always worth to ask here, thanks again!
