View Full Version : Large Image Map = Crash LW7.5c
04-07-2004, 04:55 PM
Sorry to bug 'yall with this but it is getting really annoying...
I am trying to make a fairly hi-res Earth model for a commercial type promo, and everytime I import a very large image map (8192 * 4096 color image of Earth - you know, the one from NASA) LW crashes. :cry:
I have tried rebooting, closing everything else on the computer, and I'm not really sure what to do next.
System specs -
2 * Athlon MP 2000+
Ti4600 vid card
the rest is just ordinary...
Thank you for your help in advance.

Do you need to see the OpenGL textures?
If not, deactivate the OpenGL textures and import it. I do that whenever I need to handle large imagemaps, and I have never had any problems even with quite huge imagemaps when turning off the OpenGL textures.

another option, is to use one of the lower res image maps if you have to see the image, and then when you get readyt o render use screamernet, and simply edit the LWS file and replace the low res image mapped Geo with the high res imaged GEO...this does mean you need to save out 2 copies of the object as well.

I usually fake things like that by using a small image map when the planet if far away, and the when the camera gets close enough to see details, dissolve in a small objects with just part of the high res image on it (only the part that's visible to the camera.)
This also saves render time :)

Try re-saving the image as a different format 24-bit tga/tif or bmp. The tga image off of the NASA site has an alpha channel in there that might confuse things.

7.5c = BUGGY period We were running into all kinds of problems with wierd things happening. We went back to 7.5

I just did that recently.
Firstly, you want to make it an un-compressed targa, that way, when Lightwave loads it, it doesn't have to decode it.
And then secondly, give it about 30 mins to load it, personnally, leave it till you actually do the animation, so just do a small one, so you'll have a general idea for your animation, then just load up the biggie. Don't touch anything on your computer, just let it load!

I changed the OpenGL settings in the Display panel and everything seems to be okay.
Thanks for all of the other tips too.
Besides this one time, I have had notrouble with 7.5c yet...go figure.
You guys all rule! :bowdown:
wow nice system don't know why ur having that probelm glad you fixed it what format where u saving .....try tga or png format how big is it i usually can go 3000x3000 pixel res about 300:surprised
i installed 7.5c... since ive installed it like two days ago cuase i needed the surface thinkness option..ive come to realize is finicky like someone sed in this post b4..i want to go back to 7.5 but its to much of a hassel

In my experience surface thickness is a joke, when it isn't crashing the system it's less than spectacular.
Have you had any luck with it Ziah?
Sorry to go so far OT, I think the issue has been resolved.
yup i was actually worth it...
Um for a test of ur own if you don;t have any exp on water ( yeah right you know so much from what ive seen)... use the simply lightwave ocean tut and then use surface thickness to controll the transparecny graident when you have a wave or a rise in the diplacemnt you can get some good results
if you get a chance ucon go here
its a board on the NT forum look at some baci stuff that it was used for image when devloped more what could be done :bowdown:
turn off texture display or work with smalest map.
Lw can't show huge image map.
I tought it was my Nvidia card and some driver problem, but with certified one, the problem is same: crash.
I hope lw8 come with new driver compatibily.

Thanks Ziah thats pretty cool.
tais: OpenGL can't display larege images, you are restricted to sizes like 1024x1024 and maybe even as high as 2048x2048 but anything in between will snap to these values. All 3d programs that use OpenGL to display are like this.
Lightwave can render almost any size image, there are restrictions. I don't know what they are off of the top of my head tho. It also varies from machine to machine.
no prob ucon thats why i installed it don't know if it outways the bugs yet tho :D
ok, thnks uncon, btw, i saw it work well on 3dsmax, maybe it prefer to convert it to a more small size. Lw prefer crash.
uncon, gradient thickness fonction i reall nice when u need to make sea depth and foam around island. It crash if you turn off Raytrace transparency.
