Here are couple of images with terrain self-shadowing in action.

There are still several issues and bugs to solve before it can be made public though, as it doesn't work in all conditions yet. I've selected only the nice ones :)

Woo! I've been waiting for this update! Looks great, I can't wait to see it in action. Great work!
-
NICE!
-
It is not just better, it almost changes the whole thing! Now it gives me the motivation to do an other time-lapse video.
Congratulations, Cameni.

how easy would it be for you to add in shadow PCSS? was gonna ask if you could release the uncompiled shaders so i could have a look myself but seeing as how your messing with them atm here's the link for the shader source...http://developer.download.nvidia.com/shaderlibrary/webpages/shader_library.html#shadow_PCSS (http://developer.download.nvidia.com/shaderlibrary/webpages/shader_library.html#shadow_PCSS)

Does it block the sun haze that appears through the mountains? Like this.

Amazing! Great update. The self-shadowing looks pretty cool!
-
Talk about doubling the quality of this engine.. Keep up the great work !!!
-

Not yet, it's one of the things that need to be fixed.
-
Does it also have issues with really acute angles of the sun?
I tried some terrain self shadowing and remember having huge problems when the sun approaches the horizon!
-
Yeah !
Quick questions :
How much is it affecting framerate ?
Do you plan to add soft shadows ?
-
We didn't make any measurements yet, as the algorithm is going to change, to fix glitches, expand the range. It should speed it up as well.
Acute angles - the light gains darker orange colors, contrast is lower, so the errors are less visible even though that case can be problematic. But it's too soon to tell too.
-
A bit off topic and I know there isn't actually a real sun in there yet, but is the optical illusion that causes the sun/moon to look larger at the horizon be doable? And would it be an actual optical illusion or just making the sun physically larger when it's at the horizon?
-
I logged in this afternoon, and missed this thread completely. Log in now to clean up the unread posts icons, and kick myself in the behind for missing it entirely.
Holy cow, that's gorgeous :) I can't wait!

Well, since the illusion is in your brain (http://en.wikipedia.org/wiki/Moon_illusion), it should work without us doing anything, as long as there are accompanying details near the horizon that make up for it. I personally never noticed Moon being extra larger, except in Hollywood movies and infected games. We won't.

Whaaat... That's bullcrap.
I was taught that it does magnify it and on several occasions I've even seen weathermen say that it does... Not that they're accurate. :P
-
This is looking and getting better and better. Keep it up with the amazing job!

It's an optical illusion. Get a used TP cardboard tube, or one from paper towels. Look at the moon when it's directly above, and then look at it when it looks bigger toward the horizon (first without the tube, then with). It's the exact same size.
-
I recall hearing something about the atmosphere warping the view to space when you look via a severe angle IE the horizon. Not going to argue whether that was true or just BS.
I can't wait to do my FOV speech discussing "the man on the moon" when people start complaining the moon looks too small. This might be the first game to put the moon to actual scale. I have to believe most games double the moon or more to make it appear "correct" with 90° H-Fov.

Looking better all the time guys!

It's not an illusion - it's just a distorted image of whatever you look at through tons of non-uniform air:

OK - didn't know that; all I knew of was refraction. Thanks, I'll have to try it out next time!
-
It's actually only half-correct ... there IS a slight change in size due to atmospheric refraction, but it tends to "elongate" the object viewed, rather than magnify it. The toilet-paper roll experiment will solve the issue once and for all for anyone who engages in it. Also, the camera experiment will do it too.
I'm an amateur astronomy (well, more accurately, I used to be, but thinking about taking it up again soon, now that there are telescopes that allow anyone to control them -- See this article (http://www.astrosaur.us/2012/05/01/amateur-astronomy-without-leaving-the-house/) for more information -- I haven't tried any of it yet, but I'm taking my timing learning all about it before I take the plunge). Lot's of cool stuff out there to be learned.
And er, sorry to hijack the thread, Cameni :) *cough*

One thing I've just noticed, the trees don't cast shadows

Until trees are real 3D objects and not flat 2D sprites, I guess it is safe to turn it off for now :)
I've got a question, not exactly related to self-shadowing itself, but will it be possible to add time command when you'll release it ?
(see this topic : http://www.outerra.com/forum/index.php?topic=813 (http://www.outerra.com/forum/index.php?topic=813) ).
Making a time-lapse video with self-shadowing will be just wonderful, in my opinion !
