Slow IPR in Simple Scene (C4DtoA 2.4.1.2 + Arnold core 5.2.0.1 on Mac)

[matthew]

IPR session takes 30 seconds to initiate the render of
• A cube
• With a default standard surface
• With a point light

Once the file is sent to IPR it is responsive - moving the camera, the scene renders in less than 1 second. Closing the IPR window and launching it again = 30 seconds of black screen - then the image pops on quickly again. Then for the most part it remains responsive, but randomly kicks back into slow 30 sec. loading time. It doesn't appear to be a Shader change, or Geo change or lighting change, but any of those can trigger the 30 second load time.

Any thoughts on this? My older version of c4dtoa at home pushes the basic scene to the IPR instantaneously.

Also separately, "Substance materials" are very slow to edit in the Network Editor. Nodes are unresponsive when grabbing them to move, or duplicate, or rewire. for up to 5 seconds.

Did you try the older version on this machine?

What does the Arnold log show? What's happening, if anything, during those 30 seconds?

[matthew]

hi @Stephen Blair

Thanks for your response. I opened the Console window and there is nothing happening. Interestingly I rendered to the viewport instead of the IPR - which I never do when using Arnold. In that window at the bottom status bar it says "Preparing..." for 30 seconds - then it renders the cube from the 30 to 31 second mark (1 second)

It's as though its calculating Displacement Subdivisions or something but there's nothing but a cube and default material.

The older versions (older than ~3 months ago) on this machine didn't have this delay. I in the last version or two this issue popped up.

[Stephen.Blair]

Can you set the log verbosity to Detailed (in the Render Setings), and then post the log (or send it to support) ?

[matthew]

Hi I just ran the same setup - with log set to "debug" it is clearly hanging on this line for 99% of the 30 seconds:

C4DtoA | 00:00:00 746MB | authorizing ...

Is that useful info?

the render line says:
C4DtoA | 00:00:32 769MB | render done in 0:01.954

Let me know if you need more. Thanks!

[Stephen.Blair]

That means it's licensing.

What kind of license do you have? Is it RLM (monthly subscription) or an Autodesk license (annual subscription) ?

If you enable Render with Watermarks (Skip license check), does the 30s lag go away ?

That's in the Render Settings, at the bottom of the System tab.

Can you close the IPR window, and run the licensing diagnostics?

Hi,

I believe we have a 10 pack annual RLM. I did just turn on watermarks and yes that lag goes away. Closing IPR and going to license diagnostics it is stuck on "Checking Status..." indefinitely (in watermark mode on and off)

Thank for you help - I may have our IT restart the license server

[matthew]

Hi It finally kicked this out after a minute or two :
I've removed some specific info where you see ****

We can see that it took 10 seconds to get a license, which is really slow.

This part of the diagnostics suggests there might be a problem connecting to the license server computer:

[matthew]

OK.. Thank you for your help! - I'll have our IT take a look at it.

[uiklid]

@Matthew Turke I have both same problems: IPR is super slow (not as much as you but slow). In my case as soon as I open an high poly obj the IPR becomes smooth (after 10 seconds more or less...really weird).

Substance materials are also very slow to edit in the Network Editor for me...A real pain to work with. I can work with any 8K textures in the node editor but substances textures are totally lagged.

Looking since many days on various forums to get the answer, any updates are more than welcome!

[peter.horvath6V6K3]

I think this is a different issue. Matthew's delay is definitely caused by trying to connect to the license server.

So far I was not able to reproduce the lags you experience, which makes it quite difficult to fix, but I'm trying.

[peter.horvath6V6K3]

Regarding the substance assets in the network editor, I was able to reproduce the issue, trying to figure out what's wrong.

[peter.horvath6V6K3]

This is now fixed and will be available in the next release.
