Thanks for reading and thank you again for the help in advance.

I want to create a large neon sign (think stark building from avengers) one sided white glowing letters. not even sure how to make letters as blocks for the base of the sign (not sure how they get those super smooth curves)

2ndly… if i wanted decals on frosted glass how would i go about doing this… do i need to make a frosted glass texture? or is their a way of doing a decal on the glass that covers the same function.
( Something like this Custom Etched Vinyl Window Decals | Carson, CA ) obviously not that particular logo but the style if possible. (if i can figure out how to do that with text or imported decals?)

sorry for the newbie questions!
