Well.
You can do this a multiple number of ways, I'll give you a few.
1 ) using bricks
Using bricks with a near to transparent transparency can be used alongside good use of PointLights to create a subtle sunlight effect
2 ) using light
Although this may be the most efficient way of doing this, it may not be the neatest.
3 ) bloom
I dont know how bloom works but you could always try it |
