There is no MaskedLitSpriteMaterial anymore

I upgraded my project from 4.13 to 4.14 and now there is no MaskedLitSpriteMaterial anymore…
This forced me to replace all materials used in all sprites which was a nuisance btw. But i did and copied the DefaultSpriteMaterial and changed the graph to use the base channel instead of the emmisive one - but its not working, all my sprites are just pitch dark and lights does not affect it at all. What is wrong?
