View Full Version : 2010- shaded display 'explodes'

Okay, finally leaving 5.1 behind, but the transition is bumpy.

Installation of the trial version goes smoothly, until a polymesh is created.

On the first run, wireframes are displayed correctly, but after switching to a shaded view, the faces are being drawn from the center the object to the horizon in an unidentifiable pattern. Looks like the big bang, if the universe was a cube. The wireframe, highlighted in white, remains correct however.

On XSI restart, creation of standard primitive polygons begins working in shaded mode, but after manipulation, both the wireframe and shaded faces 'collapse'. The following example is what happens when changing the primitive subdivisions; extrusions and duplicated faces produce even more chaos. There is only one object in this scene; notice that the rendered version remains solid.

I just spent 90mins in chat support with HP getting my (elusive) video drivers and bios up to date. I renamed the XSI users folder. I even unplugged my second monitor. After 2 reinstalls, no improvement. (Oh, no actually, I always got a crash error when exiting XSI 5 or 2010 and that has stopped since the bios update).

Any ideas about what would cause the above insanity? Any other solutions beyond the video drivers and bios?

Thanks, Tui

EDIT: Oh, I'm waiting on the SP1 patch, so that's a possible solution as well. But any other ideas please, all are helpful.

Just guessing here, but could it be the anti-alias setting in your graphics card driver, as described here:

(Basically it says, the anti-alias setting in your graphics card driver should be set to "Application Controlled" (or something very similar))

ATI card or NVIDIA??

ATI cards have some issues with Softimage, and if I recall correctly this was one of them.

This has come up before, maybe searching XSIBase might help too.
Or http://xsisupport.wordpress.com/

ATI/nVidia? I wish! No, it's an Intel (965 chipset family... sigh)
And there is no Anti-Alias setting that I can find, although I've seen that problem before, it happens on my secondary monitor. but not my problem here.

I did search here, the reference, and XSI base, but didn't know about the wordpress blog. Score! I have found the official problem :beer:

Thanks all for the replies, wish me luck on the actual solution,

Intel integrated graphics + 3D apps = problems....

Unfortunately it's a laptop, so you can't switch. Good luck solving it.

RESOLVED.

Thanks for the replies! As always, they are all immensely useful.

Turns out the xsiSupport blog's advice was perfect:
Solution
This problem is usually seen with older graphic cards or integrated graphic chipsets.

Try setting the XSI_EMULATE_OPENGL environment variable to 1.4. Add this line to your setenv.bat:

set XSI_EMULATE_OPENGL=1.4
Had to place it at the beginning of setenv.bat and reboot before it took effect, but it worked.

Good old retrograding :beer:
