Try no far value definition so it will be 2000.0f and SSAO_REACH 45-50

Have the same problem too. Some ugly black outline appears

Really strange things when I launch your example (anyone) I have an 1 pixel line drawn at the left wich seems to be normally drawn at the right.

Sounds like the half-pixel offset to me. At least that's what I think it is.

I'll wait for BlindSide to confirm or reject that notion.

I try mix XEffect depth map with leadwork SSAO this is result:

Sample 1
SSAO enable:

SSAO disable:

Sample 2
SSAO enable:

SSAO disable:

I don't know this is edge detection or real SSAO but it good for me and it can use far far away distance

Wow those are some impressive screenshots. Nate_D do you mind posting exact code, also what video card are you using? Also I forgot to ask a very important question, what driver is this?

wing64, those screens do look impressive. The FPS is kindof unpractical dont you think?

btw, great update, thanks for the feature BlindSide (Halifax's original contribution too)

Ther's no difference in SSAO and no SSAO FPS co it's very practical

For whom it may concern. While using XEffects, don't enable AntiAliasing. It's $#@% the scene. Took me 3 hours to figure it out...

Here's a screeny of how it looks with AA on (orange backgrounded window):

The other window is reference (as in no XEffects at all).

You can do anti-aliasing yourself manually by passing a bigger ScreenRes than the driver resolution and then downsampling in the last shader.

Hi,
I tried to use a tree with xeffects but the shadows are wrong.
The alpha values of the leafes are ignored by xeffects although
I set emt_alpha_channel_ref as materialtype.

Here's a screenshot of the tree without Xeffects:

Here's a screenshot of the shadow of the tree:

I guess Xeffects does not support any alpha values in shadows ?
And If yes how is it possible to add this ?

BlindSide · Post by **BlindSide** » Sun Mar 22, 2009 12:43 pm

I was planning to add support for ALPHA_CHANNEL_REF some time. It will require a bit of a change to the shaders, so you can't just change the Depth material's base to REF. ALPHA_CHANNEL and ADD_COLOR are of course not supported because that would require true transparency.

If it is important you can bug me personally about it and I'll send you some kind of temporary fix.

Could you tell me where changes are necessary that I can
do it on my own ?
