Texture disappears in perspective view

[alexx]

yep..
i had that as well..
getting a geforce quadro2 pro helped

cheers

(but i still think it is mostly a driver issue, since with my old geforce 2 gts i did not have it all the time.. but can´t really remember anymore)

Well before you go and buy a new GFX card (Don't spend your money on faster CPU, unless you really want i.e. faster rendertimes or such. Everything you see (Or don't see ;)) while working is done by the GFX card, and if you're having problems then they are related to the GFX card), you should try out the newest Rivatuner.

You said you've used Softquadro to mod your card? So did you use the actual Softquadro, which you patch your drivers with and then load in the patched drivers?
Well, the newest Rivatuner has this small utility, NVStrap which does what SoftQuadro, except that it actuall works :)
You should search this Maya forum for a thread named "Maya window slowdown" or something like that, atleast there was that "slowdown" -word at the subject, there has been some discussion about this topic.

For me, changing from Softquadro to NVStrap fixed Maya crashing, weird slowdowns at every restart of Maya, numerous graphical problems and etc.etc.
I really recommend it. As Softquadro never really worked 100% ok, NVStrap makes your card a perfect Quadro, except for the clock rates ofcourse, but you can overclock your card with Rivatuner and then you can't tell the difference from a GeForce and Quadro ;)

And I'm using GeForce2... or should I say Quadro 2 Pro :love:

Hi,

thanks for your tips!
I installed the RivaTuner and Detonator 30.40.
NVStrap does not work. At least it does not fix my gfx problem. The texture still disappears after some texture reloads.
What are my options now? Any idea?
Buying a real Quadro gfx card really helps me getting rid of this problem? I got to check the price of such a highend gfx card...

Just making sure before you buy a new card... How does the NVStrap not work? Did you install the NVStrap dirver, and after that changed the "Professional Quadro Capabilites" from "Determined by PCI DeviceID" to "Force on"?

Oh and after you installed the NVStrap and rebooted, did Windows make you reinstall the Detonators?

[lutz]

It does not work like in "it does not fix my problem" :)
Sorry to be so inconcrete. I installed NVStrap by starting RivaTuner, going to "customize low level system settings", going to the NVStrap tab and clicking "install".
I thought that should it be. Something wrong with that procedure?
No, I had to reboot, but windows didn't ask me to reinstall the detonators.

If you're getting the completly black textures after some time
in Maya, you may also want to check the AGP settings in bios.
Going from 32 to 128 mb for agp texture memory size suprisingly
solved the problem on couple of computers here.

Yes, the procedure is all correct... but it sounds like it's not working, as I had to reinstall my drivers, and I understand why too...

So, you clicked install and then rebooted, so you didn't change the "Professional blahblahb..." setting at all? As NVStrap won't do anything before you actually change any of it's settings, and to make it Quadro'ize your card, you have to change that "Pro..." setting to "Force on".

[lutz]

:thumbsup:

I didn't change these settings. So now I can see in the windows display settings that a NVIDIA Quadro2 MXR/EX is recognized. Really good!! Thanks! :beer:
But my texture/maya problem still exists. :hmm:
I can't change AGP texture size in my BIOS.
I can just find "graphics win size", but I assume that's not the setting that needs to be changed.
Any other changes possible that could lead to a solution to my gfx problem?
Maybe I have to change the status of my wallet...

lutz

Good thing you got it to work as Quadro :thumbsup:

Too bad it didn't solve your problem though :hmm:.
But I doubt buying a real Quadro would fix it, as your card is now a Quadro card. The only difference would be that:
a) The new card would have slightly higher clock rates (=Faster)
b) It would maybe come bundled with some Quadro-drivers, although I doubt those would be any better than Detonators
c) You would have much thinner wallet ;)

Ofcourse I can't be 100% sure, and if you just can, you should ask if you could test the card to see if it fixes the problem, before you buy it, or something.

You could also try to select the Maya/StudioTools -setting from the OpenGL-sheet of the detonators. There's some more settings that those too because of the Quadro-mod. Maybe try to play with those too?


Other than that, I really don't know how to fix your problem, sorry.

[lutz]

Could a bigger texture memory lead to a solution?
I don't know if possible and how to increase it though...
I never noticed settings like that in maya or for my geforce2 or should I now say QUADRO2? :beer:
Anyway, Thanks a lot for your support!
I learned much!

Does one usually have the possibility to change agp texture memory in the bios?
I can't find such a setting in my amibios.

Well, if you referring the bigger texture memory as what Mandrake described, then yeah it could be the solution for your problems.
It could be just named differently in your bios. Try looking out for something like "AGP Apperture Size" or "APG Memory Apperture Size" or something. Or just anything with a memory in it's name, and options that make sense.

By the way, what's the make and model of your motherboard?

[lutz]

Ok, I'll look again in my bios for some similar words.
My mainboard is from elitegroup K7S5A.
I had several problems i.e. really bad onboard-sound with this board, but with maya I had no problem yet.
Any relations possible?

Regards,
lutz

[-wT-]

Well most motherboards contain onboard-soundchips which are just total crap, so that shouldn't be anything special ;)
And it seems to have Sis 735 chipset, and from what I remember (Haven't been watching the hardware scene for some time now) it should be a decent chipset, so it shouldn't be the problem...

Ok, I downloaded the manual from Elitegroups website, and it seems that your BIOS just doesn't have that AGP Apperture size -feature.

So, we can't be sure if that's the problem, as it doesn't mean it would be set too low if there's not an option to change it...

I really don't know what would be the problem anymore. Maybe if you have friends who could borrow you another GFX-card/motherboard to test with, or somehow get a deal from some shop that you could test a new GFX-card or motherboard with Maya before you buy.

Too bad I wasn't much help. Well, we got your card Quadro'ed :thumbsup:, but too bad your textures are still missing :hmm:

[lutz]

:beer:
You helped me much to get a clearer view of what's going on! Thanks a lot!
I'll keep on trying to solve my gfx problem. Hopefully I will find a solution in the near future. Otherwise I will have to reload the model each time I changed the texture and want to see it on a model.
Your support was brilliant! :applause: :thumbsup:

Heheh ok :)

And be sure to bookmark this thread and reply us if/when you get it working, ok? :beer:

I played a bit with the hardware acceleration slider.
When I just activate the basic acceleration than my problem persists, but I generally have more tries until the texture disappears.
But I still can't see a rule behind this behaviour. :shrug:
The only way to get completely rid of this gfx problem is to completely disable hardware acceleration.
Well, not really what I need a Quadro2 for when I can't use its features. :rolleyes:
But one way to go on without being disturbed by this annoying gfx problem.
So for now I will just switch off hardware acceleration (until I have other problems because I switched hardware acceleration off) and live with the side effects.
Ok, this is just a quick update on my gfx problem.
I'll be back when I can give more information.

Regards,
lutz

[lutz]

Bad news for me :rolleyes:
I found out that disabling hardware acceleration doesn't really help, because the texture disappears after some tries (many more than before, but...).
Now I can just reload a model to get the texture back on the model (often after a restart of maya), so I have to always reload after changes on the texture to see them on the model.
Ok, I'm still seeking a solution...
That's it for now.

Well, I tried an old TNT gfx card and the problem stays the same. By the way, the model is not all black when the texture disappears, it's all white.
That's something I don't understand either.
Just a quick update on my "progress".
TNT has a different chipset than Geforce. So maybe I'm throwing my money out of the window when buying a FireGL8800 (concerning my problem).

[lutz]

Hi -wT-,

just a simple question.
Could Maya be the source of the described problem?

Regards,
lutz

[-wT-]

Well TNT is the chip that came before Geforce, but uses the same drivers, so maybe that still didn't prove it.
Would any of your friends or co-workers have some ATI card? That would propably finally tell it if it's your card or not.

And no I don't think Maya itself is the problem, then I would have the same bug too ;)

[lutz]

I'll ask the admin in my company to lend me an ATI card.
Well, I didn't really believe it's Maya itself, but maybe some settings within which could be different.

Regards,
lutz

[-wT-]

Well atleast it isn't supposed to do that by default, Maya that is. So, if you're upto it, you could maybe try reinstalling Maya?

Ofcourse the more pleasant way would be to just borrow the ATI-card and see if it solves everything ;)
