Compiling Geometry

[waaazoo]

Hi,

Phoenix FD 3.14.00 (May 14 2019), Vray Build 4.12.02 (V-Ray Next, update 1.1 official) (1 July 2019), Maya 2018.6

I Have a test render stuck at "Compiling Geometry...". As it's not the first time it happens I thought I'd ask what is the principal cause.
7M foam, 161K splashes, 2.6M mist.

Is it principally due to the number of particles ?

[georgi.zhekov]

Hey,

Does it finish at all or it's stuck forever? From the screenshot your RAM looks good, but could it be that you run out of RAM?

If you're using Progressive - does it help if you switch to Bucket mode?

Cheers,

[Svetlin.Nikolov]

Some more info which might help - this phase is usually where the ocean mesh is built, so if it just takes long, but finishes, then you can speed it up by reducing the ocean subdivisions. If it does not finish, check drive c, phoenixfd directory, immediately after the hang - the phoenix log there might contain any errors or warnings that could help.

Hi,

thanks for the answers. Yes RAM was good at 50%. I had to kill Maya after 20min, I didn’t want to wait more.
i’m using Progressive also.
i will try again same view tomorrow.
after the crash, I used 50% of the foam particles and it seemed to work, but I had to leave office.
will give more info tomorrow. I think it is related to the number of particles...

Ah, okay, gathering particles is single threaded in Maya opposed to 3ds Max, so maybe this is taking long. If you could attach the scene, it would help. Otherwise, georgi.zhekov , please link this thread to the issue and double its value, so we check it earlier. Thanks guys!

here it's hanging again since 5 minutes at 96%. [EDIT: it started Lightcache after 10 min]. End of Log:

Ah, okay, gathering particles is single threaded in Maya opposed to 3ds Max, so maybe this is taking long.

too bad

[Svetlin.Nikolov]

Yup, it's one of the most important todo tasks. Will bump the thread when it's implemented. However, still not completely sure if we are talking about the same thing - it will take just one cpu thread and will eventually finish, but if you get infinitely stuck, then it's something else...

[waaazoo]

Hi,

I tested again same exact scene this morning. Compiling geometry was fast, about 1min. I tested several frames and different views.
I will try again with another scene where compiling takes 10min with much less particles. Will check also the settings on the ocean mesh & smoothness.

[Svetlin.Nikolov]

Oh, if it's not proportional to the number of particles, then it really might be a different thing, especially if there were no changes to the count multiplier or size multiplier, or optimize congestion as well.

Compiling geometry really takes a long time, sometimes. Going slowly down to 10% CPU usage, then suddenly going up again when it's close to finish. Would be great if you can implement the multithreaded compiling in Maya.
