Hey! I'm trying to use 3-D Studio 3.0 (Rev 2) on a Novell network (3.11) and it's doing all sorts of wierd things! Sometimes, I can render everything just fine, and then it will often just lock up with "video noise" (only way I know how to describe it – black and green dots along the top 1/8 of the screen) on one machine, and on the slave machine it will sometimes lock during a random frame either during the rendering or transforming objects phase. Both are 486/66 VLB machines with 16MB RAM and > 500MB hard drives, 1.5GB drive in the server, 2MB VLB cards (one is an Orchid F1280 VLB w/2MB, the other a Hercules Graphite Pro/VLB w/2MB). I've done my best through the dealer to get ideas and any suggestions, booted "clean" with just "HIMEM.SYS" and the mouse driver, etc – still no go (I normally have it using QEMM 7.03 with lots of stuff loaded high). I have also taken the files and put everything on the slave machine, moved the hardware lock and not even logged into the server and still get the same result(s). I've looked at the logs on the network rendering times and everything looks just fine – except the last entry is always [xx:yy:zz] Machine 2222 [486/66 Orchid] assigned frame nn… Something is really wierd here, and I've gone over the manuals front to back several times, including the "advanced" guide.

Mike, << .. all kinds of problems…booted clean with HIMEM >> A clean boot is FILES and BUFFERS only in config.sys. A PATH and MOUSE in the autoexec.bat. What resolution and color depth have you chosen with your video cards? When you lower the resolution and|or color is the screen problem the same. Are you rendering to NULL when you send the project to the slave? Did you run 3ds vibcfg on both machines? jonas[adesk]

I did have a seemingly similar problem, although I have no network. Green an black dots and stripes at the top of the screen when doing a large rendering, it always happened when I put raytracing shadows as the global setting. The project file was about 6MB, I had 100MB free on my harddisk, 20MB RAM. After doing a few 'building ray trace data' passes the computer simply blocked and the green and black dots appeared through the Pull down menu bar about twice as high. Is this because of lack of memory space??? Christophe

Christophe, << …similar problems…>> I'm going to keep asking the same question. Does this happen when you choose a different resolution and color depth? Does it happen when you choose Driver=Vibrant and Board=VESA Compatible? jonas[adesk]

It does not happen when I choose a different resolution or color depth. My setup is driver=Vibrant The Board I choose is ATI Ultra plus, although this is not exactly what I have in my machine, it are ATI chips implemented on the motherboard by Olivetti with 1MB of video memory. To my knowledge it seems to happen when the swap file gets to large although I cannot check this because to computer locks up. I'll check some other driver setups out and let you know if this happens with the same rendering at the same resolution and color depth, I'll post results in a few days.

Christophe… the symptom (dots and stripes on the screen while rendering) almost definitely means that memory is being trashed somewhere. You've got a device stepping on another device, and since it only happens when you render, it's probably a conflic (conflict) between your display card and something else (your hd controller could be the culprit). – G

I do not know if you still remember that I posted a message a few months ago, that when I saved a prj. file a few times the computer rebooted during the save, resulting in total data loss. You pointed me to the HD controller as well. The problem never reoccurred (I was running 3DS r2.01). I did thus not change my HD controller, also no one seems to be believe me since I can not simulate the problem again, and I'm not a hardware specialist. However the problem I have always reoccurs when I put more raytracing lights on, or set raytracing as a global light setting, and when I put a higher resolution on. BTW display card, memory and hd all are on the motherboard. Christophe

Well, both machines are at 640x480x64k colors. Changing the resolution doesn't seem to buy me anything. From what I've been told today by a couple of the local 3DS gurus is that MS/DOS 6.x "just ain't cool" (yet), and that I *have* to get rid of my 'Stacker' volume on one of the two machines. I am rendering to NULL when I send the project to the slave, and I did run VIBCFG on both cards… I have tried 'cleaner' as you suggested, without even the HIMEM driver installed, but that didn't do much, either. (?) THANKS FOR THE REPLY!

Mike, << stacker ain't cool yet!>> Well, that can be debated. Some 3ds users will stack only a section of the drive for executables. Others will do that plus a section containing their images. The most aggressive will also stack the swap drive. 3DS will work under all of these conditions. What happens when you put 3ds in VESA COMPATIBLE mode? jonas[adesk]

Mike – I've been following this off and on, so pardon me if I ask a question that's already been covered. Have you looked at your card and checked the Wait state. I know I was getting errors with one display card that had a wait state of zero and the motherboard is clocking at a different speed. I could get into 3DS but if I went into the materials library of started a render it crashed. I could even pull in a 3DS mesh. After that, or the next thing I did it would crash. Excuse me if this has been covered, but if you haven't checked it give it a try. -JE

3DS r3 (Rev 2), eh? New one on me. The best way to figure out what the heck is happening, Mike, is to *completely* simplify your system (NO TSRs, nothing loaded high, no network, simple-as-possible memory manager set-up (or none at all to start), and no video driver loaded or configured (render to NULL and look at the pic in another program). Remove all adapter boards except the basic VGA and controller/ I/O stuff that is critical to the basic operation of 3DS in the system. If 3DS renders OK at this point, install the video-related drivers and see how this works for you. Only after 3DS renders fine on *all* your machines in their simplest possible configurations, should you attempt to "fine-tune" each one and get things working together and at their best. Now add peripheral boards to the system. Chances are, while adding things to the system, test-rendering as you go, you'll run into the culprit(s) and deal with them on a by-problem basis, using say, QEMM to arrange memory-related problems for you. Tedious and time-consuming, yes, but often the best way of setting up a rather complicated system. If 3DS fails on a simplified system, the basic hardware/software/BIOS is suspect. The above system, however, has worked for me every time. Good luck, -Alan Iglesias
