Hey guys,

I’m using sbsar-files from Substance Designer in Unreal, but I can’t flip the green channel, the option is greyed out. I’m wondering if it has something to do with using sbsar-files…

I would be relieved if there’s a easy solution to fix this. It would be a bit pointless to manually flip green channels in Photoshop etc when I would want to use substance materials…

Thanks in advance!!

Of course, thank you so much. I didn’t even thought about that.

idk why the option is grayed out. you could invert the normal in substance.
