Easy Shadows (flat surfaces only) by daaan1+ years ago
This is the easiest way to get decent looking shadows. The only problem is that they only work on a single flat surface.

waaah, rubish...( sry:( )

but if you wanna have a stencil shdaow system, just go into my worklogs(signature or click onto my name)!

you said you will make it faster (I try it and its still not for real use)...so, I hope it will be updated soon (I'm talking about stencil shadows)

bytecode77(Posted 1+ years ago)
well, i dont know wether i can make it faster... i cannot promise you that it will be faster...

very simple, but effective for my purposes, considering that the game that I'm making is mostly inside a labyrinth, so it's going to be flat

Nice and fast, Shame if you try using more complex shapes, or have 'AddMesh' though.
