shadows

It seems the shadow function on fullscreen doesn't work in version 0.6 either. How can this be solved, or will this been solved the next version?

Please, does anybody know why it doesn't work?
IrrlichtDevice *device = createDevice(video::EDT_DIRECTX8, core::dimension2d<s32>(1024, 768), 32, true, true);
this seems to be ok.

Yes, i've got the same problem. If you use opengl, maybe the shadows work fine... but with directx (8 and 9) dosn't work (in fullscreen mode).
Please, somebody have a answer for that??

If i use:
IrrlichtDevice *device = createDevice(video::EDT_DIRECTX8, core::dimension2d<s32>(1024, 768), 16, true, true);
the shadows work fine (in 16 bits mode), but in 32 bits doesn't.

Shadows won't even work in 16 bits mode....

Hm, I think it depends on your hardware.. it works on all of my pcs..

The shadow in the FX tutorial does work, even on my PC
The source is herehttp://irrlicht.sourceforge.net/phpBB2/ ... php?t=2393.

on my bill gates pc it is so that the shadows sometimes work and sometimes not ( in 32bit fullscreen) they are always working in windows mode and/or 16 bit.

cpu: amd athlon xp barton 2500+ & 512 MB ram
os: Bill Gates Microsoft winXP + sp1
gfx: Geforce TI 4200 (newest driver)
dx: 9.0b sdk 9.0
irr: 0.6

Me neither, tho I haven't tried in windowed mode, only FS. Seems quite random I think which is weird. I've got pretty much the same system as the guy above but with a P4 2.8gHz

OK, i was thinking... if the problem with the shadows are the driver... then: why the shadow function work fine in the tech demo (with all the drivers and options), but when i compile (with dev-cpp and Visual Studio.NET), it doesn't work (with directx in 32 bits)?. I think that they're another problem.

I experiment the same problem than LordNaikon.

-My video card is a NVidia Geforce FX 5200 (128 MB DDR)

and i'm using Windows XP (with the two compilers)

I found that shadows only work when your desktop is in the same color depth as the engine. (tried this quite a few times...) If my destop was in 16bit color, no shadows. I switch to 32bit (which is what I compiled the engine under) and shadows worked fine. Hope that helps someone...

Ah, interesting.

Hi niko, I have the same problem as DarkWhoppy: Shadows work when the color-depth of windows is equal to the one of irrlicht (or vice versa

), otherwise: No shadows! Also, with shadows I have only half of the normal fps!
Thanks for your effort and cheers

That would make since as the engine would have to render those shadows.

yes, off course, but I exptected the penalty to be a little smaller. Maybe its a problem of my graphcis card or driver (ati mobility radeon 9200)
