Vantage live link stopped working but nothing changed

[TKT]

Hi

Cant seem to get vantage live link working anymore. I consistently get these warnings and it just gives up trying to link. Works on other machines but it appears something has happened to this one.

[15:23:58.901] Warning : Server dropped and there are no more render hosts that can work on the scene. Waiting for a host to connect...
[15:23:58.906] Warning : Render host rotterdam (127.0.0.1:20701) is not responding
[15:23:58.908] Warning : Server dropped and there are no more render hosts that can work on the scene. Waiting for a host to connect...

I turned firewall off but still doesnt work. Tried empty scene, doesnt work. tried same scenes on another machine, works fine.

Is Vantage running while these warnings occur? Check the live link menu in vantage, it should look like this:

yep looks like that. tried restarting my machine, stoping and starting the server. I also checked in perf. tab in max that render node was the 127.0.0.1 address and hit resolve to check it worked.

The other machine that was working fine, no longer works either. no idea what changed but its just not loading it. it says the live llink is in progress but shows nothing in the scene, just the default blank scene with a sky.

So machine 1 - wont even live link and throws up that error in my first post.

machine 2 - did work but now doesnt, even after hard reset of the machine. says live link is successful but doesnt show any relation to the scene in use. it had one error about a shadow render element not being supported and GI to be re cached? maybe something like that (i didnt get the error log for that one yet, a colleague ran into it)

anyone got an idea of what it might be?

Are you using the latest Vantage? Are there warnings or errors in the Vantage log (Help > Open debug log)? You can use the filter button at the bottom of the log window to find them quickly.

I reinstalled Vantage and it is now working on Machine 1. Machine 2 has started to work again randomly and Machine 3 now doesnt work! (new one)

Machine 3 throws up these errors - 15:55:47.112 [Wrn] Driver check warning: Driver 522.25 is newer than the latest tested version which is 497.29
15:55:48.306 [Wrn] Cannot create a connection to the 3DMouse.: not connected
15:55:48.342 [Wrn] Warning: Disabled path space filtering because it produces artifacts in multi-GPU setups.

These warnings are not relevant and can be ignored.

seems to be no other warnings other than the original ones that appear in max VFB in my first post and then these ones in vantage. I asked them to reinstall vantage like i did to see if it helped but no luck!

So Machine 1 and 2 are running ok currently.

Machine 3 is now running after finding a reality captured landscape of 17m polys caused the crash. reduction to 5m polys allows the whole scene to work. Not sure why there would be no errors regarding a poly count issue though?

However its not a problem with total poly count as the mesh doesnt it go in when isolated but a whole scene equaling a similar poly count works fine. so appears to be an issue with a single object having too many polys during live link? are there known limitations regarding this, does this info help any further?

A single large mesh will raise the peak CPU/GPU memory used more than a number of small meshes with the same total poly count.
I don't think there is any specific limitation, it depends on how much CPU and GPU memory you have.

Yes, CPU memory can also be important, as before the mesh can be uploaded to the GPU, it has to be stored in a special kind of
CPU memory that can be accessed by the GPU. Windows allows only half of your total CPU physical memory to be used for this purpose.

Running RTX 3090s 24GB with 64GB of RAM. I thought perhaps if it was running out of memory it would at least say so?

We have the "Safe GPU allocations" option in the Preferences - when it's on, it's supposed to tell you when there is not enough GPU memory.

However, when the option is off, Windows can (sometimes) swap GPU to CPU memory and it's not possible to say when it will succeed and when it will fail.
