View Full Version : Glitch: Creeping Backgrounds in Max?

Hey everyone, here is my specs..

Asus A7V333, 1.5GB Ram, 2100+ AMD...

Quadro 980XGL

Max 5.1 with Service Pack

using nvidia drivers... 40.21 or something, the latest drivers authorized by alias|wavefront, since i had been a maya user...

latest maxtreme drivers

here is my question, i am currently trying to build a model using background texture maps as a guide

the texture maps are in .psd format

i load them into max, (alt+b), lock texture map size, etc etc, so it doesn't change size on me, and then i start working...

here is where i am running into the glitch...

when i am in an orthographic viewport, left, etc... when i start editing the verts, i notice the texture on the background nudges

every time i pass the mouse over the transform gizmo, it nudges a little bit more, i can get the background really far off really quickly, all i have to do is press `, to refresh viewport, but man that can get annoying...

i have tried this is OpenGL and it does the same...

i turned on Software viewport mode, but i get a strange error,

every time i zoom in, max yells at me, and tells me that the texture map is going to use XX.XXmb of memory, and then it asks me if thats ok... looks like an unrelated setting, max is resizing the background as i zoom in, it resizes it to some gigantic size, 8100x8100, sizes like that, until max eventually crashes.. so i can't test this in software viewport settings...

does anyone by chance know my problem? is it a burried setting in my video card properties? bad drivers?

thanks for any help guys =)

and i will keep trying to trouble shoot this, such as, changing texture files to jpg... etc etc... anything i can think of, i will keep you updated

thanks again =)

map the image on a plane instead of putting it in the background.


this is way more memory efficient. won't go awol on you and you can zoom/pan/rotate all you want but the image will always be where it should be in relation to your model.

I was working through a book that had a step by step how to use a plane for the modeling process... my teacher taught us to use the Alt-B method... so in my mind I just dismissed the image plane idea...

but come to think of it, I didn't have any problems at all when I did that, thanks for suggesting it! :)

I will let you know how it works out :)

imho teachers are the last person one should seek advise from.
they are the se ancient machina that still require steampower to operate.

more often then not, i've come across teachers who hold on to ancient methods like a rockclimber clinging to a wall for dear life.

I've had image planes do the creeping also. It's strange. It usually happens when I make a subobject selection and then every subsequent click on the selection makes the image creep an increment. I usally just end up resetting max. So far that's taken care of it. I should mention that pressing the middle mouse button also resets the creeping but it dosen't stop it. I'm not sure what is causing it but I can't reliably repeat it and it dosen't seem to matter if it's maxtreme or opengl.

Hopefully it's fixed in 6. I've dealt with this for a while and it's a pain in the ass.

Using the background feature isn't very helpfull. I'd like to see an image plane management feature similar to what ships with maya. In max it would be like having the background feature interface but applied to image plane geometry. I'd just like the set up to be faster and the current scripts available while cool and appreciated aren't as deep as I'd like.

so how deep would you like the image plane setup to be huh ?
what options would you like to see ?

I have some ideas about this, it'll take me some time to write it up. I'll do this tonight and post it here.

The implementation would probably end up as a utility roll out unless there's a reason it should be used as a modifier. I'll try to break it down as completely as I can and maybe you can twist majic's arm to script it <or you could have mac twist his arm, that cat looks like he'd kick someone's ass>.

doh! it does it even with the plane and material method...

waa... :annoyed:

is this glitch specific to max 5? or quadro cards?

grr

This seems 99.9 % to be a driver issue

i had crawling backdrop pictures myself and the cause was
always a specific nvidia driver release


i would upgrade to the latest official quadro-certified driver
find them here:
-->ftp://download1.nvidia.com/Windows/Quadro_Certified/45.24/45.24_win2kxp.exe

another possible thing may be dual-planes, you should deactivate
them in the preferences->Viewports dialog

the next that comes to mind, with a quadro you have the options
to set the opengl-preferences for specific apps.
Maya makes use of overlays, but they should be deactivated
for max.This is done by setting your opengl-options for "3DSMax"
in your windows display properties dialog.

I have this same problem occur with just a vanilla GF2 GTS card, and the lastest official nVidia drivers (not max approved). It doesn't seem to always happen... but yes, very very annoying when it does!

hey spacefrog, i tried that dual planes trick and it worked like a charm!

i wasn't able to replicate the glitch, i updated everything before i tried it, but at least now i have all updated drivers and such =)

thanks again for suggesting it, i was pulling my hair out!
