So what do you guys think is wrong with this...I have my perspective view on smooth shade but sometimes you can see through it, doesnt' make since. Is it suppose to look like this?

precision problem. there is not enough accuracy in the z buffer to tell apart the position of the grid lines and the position of your polygons. More expensive video card would solve this.

Flip Polys?
Hit 'F' key.
Leave unselected to do all of them or select the few that you think are giving you problems.

maybe this will explain better in this image, if u look u can see how I selected the top polygon yet I can see through it, what can i fix and how?

ness jp...thank you i think thats what it was, and mike I think ur also right its time for a new graphics card!

oh, just select all the polys and flip them using 'f' on your keyboard!

Yeah, I'm having a similar problem, wish It was as easy as the 'f' key.. I get a lot of garbage lines that make it hard to tell whats actually there. When I zoom in, they dissapear. Problem is, I upgraded to a more expensive card THEN I started having this problem. It didn't happen with my cheaper card. Is there a way to hack these cards (Nvidia) and increase the precision of whatever it thats causing it to render like this?

Or more accuratly, the drivers that are used with a more expensive card...

This thread got me thinking, so I installed the SoftQuatro4 driver hack on my Gainward G4/4600. After installing, the z-depth problem is fixed, no more "eye popping" or clothes cutting into characters when I zoom the perspective view. I can set the Perspective Ammount in Display Properties anywhere and the model displays correctly.

It's not a solution I'd recommend though; the display feels a lot slower (I'll try some benchmarks later), you need to use older Nvidia drivers, and the process of patching them is moderatly involved (not recomended for someone unfamiliar with hardware/driver wrangling). Also, using hacked drivers is asking for stability problems.

I'll probably go back to the "correct" drivers and live with the display errors if the benchmarks confirm the slowdown.

The other 3D apps don't have the display problems, even when using the "consumer" card drivers, so it seems that the problem is partly drivers, partly LightWave...

Terry

I have the problem of (random) polygons disapearing when I make selections in the smooth shade view.
I have a radeon 8500 LE, and it seems to be a driver problem. When I 'hacked' my drivers into a fireGL card the problem was gone, but I had a lot of other problems, so I switched back. And decided to work in wireframe smooth mode most of the time.

Guess it's the price of using a game card :hmm:

I have a similar prob when i did some clothes for my model.they were in a separate layer and in some part i coudn't see these clothes that were very tight on the skin . my pc is quite old. the prob disappears when zoomimg, so i don't worry because i know polys are there. try to turn off the grid.
