Open the file more than one hundred times, resulting in a crash

mx_zwh — Fri, 17 Feb 2023 07:18:30 GMT

-------------------maxscript -----------------------------

for i = 1 to 200 do(
loadmaxfile XXX Quiet:true
filein YYY
resetMaxFile #noprompt

)
------------------------------------------------

It will crash at the 100th time

I see only one reason - some memory issue...

add this code to check the memory information to see how things go:

( r = sysinfo.getSystemMemoryInfo() for i = 2 to 7 do r[i] = (r[i] / 1024) / 1024.0 format "MEMORY IN USE\t (\%)\n" format "\t\tused:\t%\n" (int r[1]) format "PHYSICAL MEMORY\t (MB)\n" format "\t\ttotal:\t%\n" r[2] format "\t\tfree:\t%\n" r[3] format "\t\tused:\t%\n" (r[2]-r[3]) format "PAGING FILE SIZE (MB)\n" format "\t\ttotal:\t%\n" r[4] format "\t\tfree:\t%\n" r[5] format "\t\tused:\t%\n" (r[4]-r[5]) format "VIRTUAL MEMORY\t (MB)\n" format "\t\ttotal:\t%\n" r[6] format "\t\tfree:\t%\n" r[7] format "\t\tused:\t%\n" (r[6]-r[7]) ok )

if there is a memory leak, it is in "filein"

you could also try a gc() in the loop - sometimes it helps.

it makes a RESET max file according to the sample code above ... which is automatic garbage collection.

I tried using gc(), but the situation didn't get better. It was very painful

Years of batch processing experience tells me, There is only one way:

open 3dsmax.exe, open max file, filein script, kill 3dsmax.exe

......

you have to understand that what you're doing in filein is causing the crash... it's hard to tell what it is specifically without seeing the code. So the only solution seems possible is to fix the code you are using in filein.

This is too slow, but there seems to be no good way

Re: no

filein file sample like
---------------------------------
xxx.name = “xxxx”
max file save

have you tried just only opening files? ... in sequence

fn batchLoadMaxFiles dir: = ( if dir == unsupplied do dir = getSavePath() if doesfileexist dir do ( files = getFiles (pathConfig.appendPath dir "*.max") if (count = files.count) do with quiet on ( cancel = off for k=1 to count while not cancel do ( if keyboard.escPressed then ( cancel = on format "\nBatch was canceled!\n" ) else ( file = files[k] format "%(%) ...\n" (formattedprint k format:"03d") (formattedprint count format:"03d") loadMaxFile file quiet:on allowPrompts:off format "\t>> %\n" file resetMaxFile #noPrompt ) ) ) count ) ) /* RUN IT! batchLoadMaxFiles() */

I tried, but it still crashed

denisT.MaxDoctor — Fri, 24 Feb 2023 06:15:50 GMT

what are these files? What is the main content : animation, geometry, materials?

Re: no

mx_zwh — Fri, 24 Feb 2023 06:36:32 GMT

animation file

Serejah — Fri, 24 Feb 2023 06:55:51 GMT

did you try to load files in reverse order to ensure that it is indeed a script issue and not the corrupt scene file that leads to crash?

Re: no

Biped? Layers, Mixer?

How much memory do you initially allocate?

Re: no

mx_zwh — Fri, 24 Feb 2023 06:59:04 GMT

default：100

Re: no

denisT.MaxDoctor — Fri, 24 Feb 2023 07:27:56 GMT

Find one file that crashes the system due to 50–100 loads, and post it here. I will try to find a time to look at it.
I don't see any other way to figure out what's going on.

Re: no

mx_zwh — Fri, 24 Feb 2023 07:30:46 GMT

It's not a file problem. It's a problem with 3dsmax software. I changed different files. It's all like this，lol

Re: no

denisT.MaxDoctor — Fri, 24 Feb 2023 07:50:34 GMT

What if I tell you that some of my batches are 400–800 files each and they work stably?

However, it is up to you... You can blame the software if it helps you in any way.
