Im a total newbie on how to really generate materials. I wondered if someone could teach me how to do the following thing:
The material(-background) should be transparent - but draw a black vertical stripe each “distance x” next to each other.
To further explain what I want to do: http://i.imgur.com/sfHribE.png?2
I have a hp bar (progress bar) in the widget. Id like to have for every 100 health a black stripe. I made a shady one to test in photoshop - but it doesnt work too great with tiling per numbers - I thought there has to be a great way to mathematically express that in a material but i have no clue about “painting” with materials.
All google results show me only how to mess around with other things. I hoped some mathematical material genius can bring me on the right track.
I also browsed the material expression reference and I was completely overwhelmed.
