Do you have modifier volumes enabled?

Original comment by Mr.PsyMan on 10 May 2010 at 11:41

GoogleCodeExporter commented 8 years ago 
Yes, modifier volumes enabled.

Try changing Z-Buffer mode. Might be working with one.

Original comment by Mr.PsyMan on 10 May 2010 at 11:48

GoogleCodeExporter commented 8 years ago 
I try all Z-Buffer modes: D24S8 Mode2 (lower precition), D24S8 Mode1 (lower 
precition), 
D24S8+FPE (Slow, good precition), D24FS8 

Shadows of characters not displayed, this problem make game not playable when 
fight 
with Ghost Boss, i can't see his shadow.

Will investigate, maby, if i'm not bored, and its not rainy, nor too sunny or 
hot
/me suspects it has to do with Z buffering

I was testing Dead or Alive 2 and Soul Calibur, and same issue. No matter the
Z-Buffer mode used, no kind of shadow was shown, not even MV: Volumes showed a 
thing.

Looks like i found this problem, this happen only on Radeon video cards, i ask 
on 
forums and people say what on GeForce all work perfectly, but all users with 
Radeon 
have problems with shadows in many games.

Strange, one user say what he have problems with shadows (GeForce) :-/

Mine:
Windows Xp sp3 x86
GF9800gt

Shadows work only on Zbuffer Mode: D24s8 Mode2(lower precition) with graphics 
bugs
(in SA2 for example)
Shadows working nicely not everywhere!!! In Nulldc 1.0.3 much better!

There's no shadows in Shenmue, Jet Set Radio, Powerstone 2 and Zombie Revenge 
unless 
you use the lower precision Z-buffer, though Dynamite Cop has shadows on every 
Z-buffer 
setting.

Using a Geforce 8800 GTS here.

Changed summary since it seems to affect more games than just SA2.

Same for Daytona USA.

Shadows only works if lower precision mode 2 Z-buffer is used, the rest no 
shadows.

GoogleCodeExporter commented 8 years ago 
Just to add the same for Test Drive Le Mans.

Shadows only works if lower precision mode 2 Z-buffer is used, the rest no 
shadows. However it's glitchy, too. Shadow of my car only appears during pause, 
it disappears if i'm playing the game. The way the shadows of other cars appear 
during race is also weird. It seems that there's some kind of invisible texture 
blocking the shadows at certain angles or positions.

Alright, here's the list for ATI cards:

ATI 5770HD => No modifier volumes of any kind are visible. =P

Note, this is about Modifier Volumes shadows. As opposed to sprite based 
shadows like a dark smoothed circle under characters for example. 

Note that Grandia II does have a circle... but it's actually a modifier volume. 
XD

... Really very bad thing with ATI, you know... :(

But what did you say about bugs textures+poligons on Zbuffer Mode: D24s8 
Mode2(lower precition) for ATI? 
I think its different...

 vadimur@yahoo.com, 15&16 possible to add for my list for NVIDIA. Thank you. 
But I ask about ATI! About poligon & textures bugs on ATI card when we must see 
a shadows...

I don't know about what you're talking about. Keep this Issue focused on 
Modifier Volume shadows.

There are already enough titles to test the Issue. Until there's any commit 
about it, there's no need to bump this Issue.

New PowerVR Plugin appears to do the trick... Have tested Crazy Taxi, CT2, 
Sonic Adventure 2, Jet Grind Radio.  ATI Radeon HD card modifier volumes all 
now functioning correctly as in 1.0.3

Also, as a follow up, Have tested Shenmue and all four different Z-buffer 
settings and all show shadows fine (modifier volumes normal+clipped).  Problem 
definitely appears rectified ... excellent work KrossX3!!

Fixed by r48. Thanks for the testing!

Ok! I understood! 

That is why I created issue 130.

Nice. Seems to have fixed the shadows for most games, however, it's still 
glitchy for Test Drive Le Mans. There's seems to be a invisible square texture 
in the middle of the screen blocking shadows showing or affects how the shadows 
appear from the other cars. Anywhere outside of the 'square', shadows will be 
visible.

Doesn't seem to be a shadow problem, but also something else. If you press 
start, the shadows are visible. Something's just covering them. >_<

Yes! In my comment 16.

Related to z-buffer? O_o

Hey Kross, can you give antoher link for your solution? It dissapears! And i

The issue has been already fixed. Just use any new revision.

But i have the 1.0.4 r50 version and i have the problem, is it normal?

Original comment by cpei.lic...@gmail.com on 10 Dec 2010 at 8:56

GoogleCodeExporter commented 8 years ago 
It's either another problem, or a wrong configuration.

Original comment by KrossX3 on 10 Dec 2010 at 9:15

GoogleCodeExporter commented 8 years ago 
But i don't understand: the problem should be solved with my version? The 
shadows indeed appears when the zbuffer is in the minimal, but in the 1.03 
version, i didn't have this problem.

Should i stay in the 1.03 version? And finally, what are the good updates with 
the 1.04 version?

I'm sorry, but how do the sources work? we have to download it? it's like a new 
vesion of nulldc? There are 108 versions! Which should i download?

Dude, it's fixed...what are you not getting here. Sorry the way to make it work 
is not exactly the same as a 3 year old version of the emu.

Just stay up to date:

GoogleCodeExporter commented 8 years ago 
Ok but just one last question, i'm very sorry!

Is it normal if i have to the zbuffer in the lowest precision to see the whole 
shadow? if i put it in "fast when available", i just have a part of the shadow 
in Shenmue, in kinf of circle, not the whole body!

Thank you!

well, E6850, 8800GT, 2go ram DDR2, driver nvidia 260.99

There are no reasons that i still have this problem!

And i put: textures dynamix full, sort per triangle, voulume normal and clip,

>>>>>cpei.licence3

No, no, no! 260.99 is very bad version of drivers for your videocard. Belive me 
I know. Cuz problem of shadows appeared somewhere in the 256....260.99 versions 
of drivers. I tested it!

 You can fix this problem just easy. You need to download and reinstall drivers. Try something around 181.71 - 191.07 --  wonderful drivers! But I recommend: 
"182.06_geforce_winxp_32bit_international_whql" (for XP) and

 185.85_desktop_win7_32bit_english_whql (for win 7 only)

And you will see. Shadows works.

P.S.

It is only problem with drivers, and nothing more.

GoogleCodeExporter commented 8 years ago 
Wow! Thank you, i will try that! But how could you find this solution, it's not 
easy!

But you think that 260.99 is a bad driver in general or only for emulation?

Original comment by cpei.lic...@gmail.com on 11 Dec 2010 at 8:26

GoogleCodeExporter commented 8 years ago 
And just a precision: with nulldc 1.03, i didn't have this problem! 

So shouldn't use 1.03 version? I have to admit that i didn't see many 
differences in 1.04! And of course, i play on recent games and last drivers, 
obviously, are better!

Original comment by cpei.lic...@gmail.com on 11 Dec 2010 at 8:34

GoogleCodeExporter commented 8 years ago 
>>>>>>>cpei.licence3,

In general ofcourse! Cuz your videocard is old. 

260.99 better for new videocards GTX460 - 480.

Just dont worry and be happy! Enjoy!

P.S. By the way,... for example on 

182.06_geforce_winxp_32bit_international_whql"

and

185.85_desktop_win7_32bit_english_whql

 you can play in new games and old games like "Soldier Of Fortune - 1" without problems. BUT on 260.99 you cant do that.
