HtoA Generating scene time single user

[kg2040]

Hello

With single user subscription, I get slow, double 'Generating Scene' time vs rendering with watermarks (Skip license check).

Indie/6.2.1.0

Thanks

How slow? Two seconds slower? That would be about average for a license authorization.

If you get an Arnold log, we'll see how long it takes.

Instructions for generating full verbosity log files are available for MtoA, MaxtoA, C4DtoA, HtoA, KtoA, and Kick.

Hi all,

same here, 2-4 seconds are lost every time I hit the Render button.
Is there anyway to speed up this process or do the license check any other way?

Best, Manuel

No, that's how long it takes with the current Autodesk single-user licensing.

Will this be changed?

2-4" are a lot when rendering large sequences ...

[Stephen.Blair]

Maybe, I can't guarantee anything.
Single-user licensing was never intended for render farms, mostly because of the requirement to sign in on every machine, every 30 days.

Hi all

Thanks for the answer.

With license around 4.7sec
Skip license around 2.3sec

After the quick and easy activation process, this is an unexpected surprise.
I have a lot of start/stop - add/del geometry, switch shader/skydome texture, etc.

This every start/stop license check on every subscription, or just the single monthly?
Any planned improvement on this function? (eg.: check just once at loading)

Thanks

When you start a render, Arnold checks out a license. It can be an IPR render, or a render to disk. The license is checked back in when the render finishes. It doesn't matter whether it's single-user or network, it's always like this.

Arnold does check at loading, but it is when Arnold is loaded to do a render. Arnold is unloaded when the render finishes.

This also aplies for local rendering of a larger sequence.

As Gabor said, its more a problem for lookdev.

An ideal solution would be that Arnold checks the license in when Houdini is starting, not everytime a rendering is starting.

For now I use "skip license" for lookdev — not an ideal solution.

HtoA does a license check at startup...if that fails, it never tries again. But Arnold licensing is not "one time only and it lasts all day". It's per frame or per IPR, because when Arnold isn't rendering, Arnold isn't running.

We agree about the 2 seconds and we're pushing for that to be improved, but for now there's no solution.
