Why is IPR behaving like this?

[paul.sheehyECZEJ]

Hello everyone,

(Running MtoA 3.0.1.1 Arnold Core 5.1.1.1 in Maya 2018.4)

I am in work and I am running IPR and even on basic scenes like a sphere on a plane, with one light - this seems to be acting strange. By that I mean, when doing edits, rotating the camera around the objects etc. There seems to be a delay, but it is random. Sometimes it runs ok, and then all of a sudden stalls, then becomes responsive again.

Can anyone suggest any setting that might need to be changed? Surely it is meant to be better.

Thanks

Paul!

Can you update to the latest MtoA?

Have you updated your graphics card drivers?

Hi Lee, thanks for the reply. I will mention it to the 3D Supervisor about updating to the latest.

I did manage to get it to run as I expected though, by changing the Save UI Threads to 3 in the Render View settings. Can I ask, what do you have this set to yourself Lee?

[lee_griggs]

I have it set to the default (3).

btw guys are you on windows .. on linux I keep it at zero and works just great 🙂

[lee_griggs]

Yes, Windows 7 64 bit for me.

Oh yours defaults to 3 Lee? Mine defaults to 1! That is strange. 3 behaves very much I would expect. It if flying along nicely now.

Do you have any idea why it would default to 1 for me?

[lee_griggs]

My mistake. My hotkey is set to 3!

[paul.sheehyECZEJ]

@ Max I am on running Windows 7 too.

@ Lee So do you mean your UI Thread gets set to the value of 3 when you hit your hotkey 3?

[paul.sheehyECZEJ]

I just wanted to add that the UI Threads defaults to '3' now. All good.
