Hi!

Is there any chance we get a preview video with the current build of shadows? I'm really curious how they look in OpenMW but not tech savvy enough to compile it myself.
Here's the build for windows.
https://ci.appveyor.com/api/buildjobs/b ... fb58e1.zip

Shadows also need configuration in your settings files, here's the ones I use:

Code: Select all

[Shadows]
enable shadows = true
object shadows = true
actor shadows = true
player shadows = true
number of shadow maps = 3
shadow map resolution = 2048
compute tight scene bounds = true
split point uniform logarithmic ratio = 1.0
polygon offset factor = 16
polygon offset units = 72.0
use front face culling = false
Thank You kind sir! Appreciated!

Please don't do this.
Do You have any suggestions regarding this? Lower/higher? Thanks!

Please don't do this. If you're going to reply, post something constructive. We already have enough issues with shitty drive-by posters, let's hold ourselves as contributing members to a higher standard.

From my own point of view, some amount of flickering is more acceptable than shadows being placed at half a meter from the caster so you'd have to lower these specific values. But of course it's up to your own views how to setup them. I'm just protesting against some specific exaggerated settings being regarded as "recommended" even though there isn't such a thing when it comes to compromises.

For more info (though this might be vague and inaccurate), in a very thin model polygons may be so close they may almost touch the other side, which causes the shadow rendering to get confused which side should have shadows in a single spot. These added settings allow the user to compromise between flickering and so-called peter-panning - shadows being detached from the caster on a certain distance. The specific values in that config file portion cause major peter-panning even though there's virtually no flickering.

There's a new commit in town, and that should basically remove the need to compromise between the two issues described above. Yay!

Can we merge this at this point? Can we get it into 0.45 so we can get it out to users for testing?

That sounds great, AnyOldName3! :D
Can't wait to see shadows in an official release.

Hmm, no I meant 0.45. I know it's on its own branch now, but we have to rebuild/retest anyway?
