Vray Proxy Workflow - Very Slow Startup times, need to resolve..

[brobins]

This long wait is related to Max's missing paths cache. You can test turning it OFF before opening the scene. Especially with locally cached proxies it should be noticeably faster.
You can turn it off with the following MAXScript:

missingPathCache.cacheEnabled=false

Some more details on it here: https://help.autodesk.com/view/MAXDE...2-E02186B34C5C

Hi there,

Turning this off speeds loading up considerably. The file now opens in sub 2min from the network share and 1min locally.

Do you know if turning it off is permanent?

[yavor.rubenov]

It should be. You can start a fresh Max and type just:
missingPathCache.cacheEnabled

it should print the current state.

Perfect, seems to work great.

Would I ideally need to disable this on all render nodes on the farm also to speed up their loading of such scenes?

Thanks again

Yes, it's per Max user.

Any clue why that cache is so slow? Are they doing something stupid like iterating over an array (in maxscript even) rather than using a hash table, tree, or other more efficient structure?

Is it just the larger number of unique assets that slows it down?

Can't really say as I only see the disassembly and it is not an easy read For what I can see - the cache seems to be spawning new threads to do the actual resolution but it seems it spawns a bit too much of them.
