问题
How we can give any complex mesh, vertex like self lighting. I tried increasing light ambient, material ambient, but as soon as it goes far it starts disappearing. I want that to be visible at whatever distance it is at. I have tried getting vertex from a cylinder then putting color in it, works fine for colors but fails at distance.
have a look here and have a look at this too
