UT 2k3 SoftShadow?

| Ive seen the soft shadows on Unreal Tournament 2003, they really amaze me and made me wondered how they did it, i mean, it looks really really good and very very fast, does anyone have a clue about it? I hear EpicBoy might have some insight :D |
| ||
| Im guessing multipass stencil buffer stuff. In other words, not efficiently doable in blitz :). |
| ||
| I believe the model shape is rendered to a low res texture and then the texture is projected onto the world (like other projectors in the game). I don't believe it's stencil. I don't know all the techy bits behind it though, sorry. :) |
| ||
| If that's how its done then it is just like Sswift's shadow system (only his system doesn't blur out the shadow to get the soft shadow look.) He may want to look into blurring the shadow image to get that look. |

| what impresses me is the blurring, it looks alot like SoftShadow technique, where the closer the object is, the crispier the shadow is, and vice-versa |

| "(only his system doesn't blur out the shadow to get the soft shadow look.)" Ohhhh yes it does! I just haven't released it to the public yet. Well I did give a copy to one fellow. But it's incomplete, I jus thaven't copied the code to the static shadow routines, and I was holding off till I did distance based fading from entity centers. "what impresses me is the blurring, it looks alot like SoftShadow technique, where the closer the object is, the crispier the shadow is, and vice-versa" I suppose this is the next thing people are going to ask me to add. :-) |

| oh... if you could implement that, im sure ull get at least 1 more sale (if you know what i mean) ;) |
| ||
| wow! can you add where the closer the object is, the crispier the shadow is, and vice-versa? |
| ||
| wow! can you add where the closer the object is, the crispier the shadow is, and vice-versa? Ofcourse you can. It's just more weighting to the blurring. Or if you're clever you do it all with the alpha chanel. But you'll need a fast edge detection routine... |
| ||
| You will have another customer as well if you put blurring on :) |
| ||
| Possibly another here as well... who knows. |
