(Fixed) Unresponsive VFB during rendering

[Dubbie99]

Often I find that the VFB stops updating during rendering. Sometimes zooming in and out will trigger an update but not always.
reducing threads to numthreads-1 and setting render priority to low doesn't help.

Sometimes Houdini will completely hang until the render finishes, then it will act normal again.

build 18.0.566
vray_adv_43003_houdini18.0.566_babb3a1_8139

Any ideas?

Operating system?

same here, win10

Also the same happens here. This only happens when using bucker render, IPR does not have this issue. My work around was to click the follow cursor button on and off, this seems to cause the VFB to refresh.
Windows 10 here also, and this phenomenon has been happening for several versions of VFH (months back). Our Houdini version is 18.0.397.

Best,
David.

Operating system?

Sorry, forgot to add = Windows 10

Yeah, this has been happening for a while and I believe it has been reported before.
Win 10 as well

Hey all,
could you please confirm that this does not happen for you if no output connections are present for the Renderer ROP? This only happens for me if the ROP is hooked up to e.g. a Deadline ROP or even a Null.

Best regards!

Ha, yes, I can confirm (using the thinkbox deadline node here). This actually also affects the Log Window (which sometimes also does not update).

Yes, all ROP nodes are linked to something (our custom deadline submitter node).

David.

Yes, Same here deadline Rop or null

[Dubbie99]

Hi,

I'm assuming this is fixed, right bdancer ?
Just tested with the latest nightly and at first look no issues anymore with the V-Ray ROP connect to something.

Best,
David.

[bdancer]

There were some fixes added, yes.

Great, thanks
