viewport shading problem 3ds max 2011

Olli.

I started getting this when i changed gfx card from ATI 3850 to GeForce GTX 570

Im also experiencing some problems where shaded+wireframe mode doesnt work very well. The shaded surface sort of overlaps the wireframe sometimes hiding it (which sucks)

anyway as said in title im using 3ds max 2011

Did you try disabling antialiasing? Historically Max has worked better with Nvidia cards.

I haven't had anything that extreme but similar, my issue was my viewport clipping bar was stretched to the max so when I zoomed out it gave me your results.

Hope that helps!

btw, I'm using a GTx 580 evga

im not using viewport clipping and i dont have AA enabled

Did you force any settings in the video card control panel?

You may want to look for an ATI driver cleaner, then reinstall the Geforce drivers in advanced mode with "Clean Install" checked.

Olli.

nope i havent tweaked any of the settings in the NVIDIA control panel except for resolution

I forgot to mention that when i changed GPU, i also changed most of my computer including HDD's and SDD's and also a clean install of windows, so theres no way any ATI drivers could still be on my system.

The problem seems to be occuring where two faces are close to each other, in which case the face in the back sort of bleeds through the face in the front.


also seen in the pic are the glitching wires. It gets a lot worse than that sometimes but the pic gives a sense of whats happening

Oh, this is simply zbuffer imprecision (the green circle). Most cards have this problem. f you get up close to that surface in perspective mode, it should diminish. And get worse with distance (and ortho viewing).

And max in particular has this problem with shaded wireframe mode, because of the way they render it... they basically duplicate the model and balloon the wireframe outward from the shaded mesh. There are always some errors with this method.

ah thanks guys i tried adjusting my clipping planes and it fixed the problem!

now i just need to figure out how to hide the clipping plane adjuster arrows when i work.

If only someone would have said something earlier :P

If you have the ability, set the wireframe antialiased.
