Daz Updating Geometry Render Freeze?

[JohnSheridan]

I set up some renders over night and when I come in the next day it has been frozen for hours.
I think I've narrowed it down to a specific character who has been in both renders this has happened to.
I've very new to Daz so I'm wondering how I go about trouble shooting this?
Should I just recreate the character and see what happens or is there a way to determine what is causing this?
Thanks for any help or advice.

Just to narrow it down a touch, what does your hardware situation look like? Namely, CPU, GPU, and RAM.

Likely not a hardware/compatibility issue, then. The only time I've ever gotten this error was a figure that had too high of a SubD that came SubD 5, which is absurd (somewhere in the ballpark of 30 million polygons, which will absolutely tank even a high-end rig's performance). The most you'll ever need for an AVN, more often than not, is 3. If it's higher than that on either of the figures, it could theoretically be causing it to hang. I'd double check on those. Here's what you should look for, your focus should be on Render SubD (though viewport SubD could help if you tend to work with Iray Preview on):



Recreating the scene isn't going to fix the problem if you don't know what it is. It could a nasty hair asset, the aforementioned SubD. I'd also try looking at your render settings. Make sure "Render Quality" is off/not enabled. Turn "Max Time (Secs)" to 0, and your sample anywhere from 1500 to 5000, depending on the quality you're rendering at. I'm assuming 1080p with those specs? So anything between 1500 and 3000 should be more than enough with an external denoiser taking care of anything else.

Just to eliminate the possibility, go to Render Settings > Advanced > Uncheck anything CPU-related > Restart Daz.

Iirc, few figures have baked HD morphs at SubD 4.

And as a rule always restart Daz Studio before launching a batch rendering session, and don't try to batch too many files at once. It's hard to quantify precisely because each render is different and will need more or less time to be processed, but globally it will need at least 1% more time for each render he previously done.
It's not too sensible when it's basic renders with a recent GPU, but when it's a complex scene rendered in a 20xx, and that is the last of a series on 20, the difference can easily reach a full hour compared to the same scene rendered after a restart of Daz.

Like it's a memory management issue, it can also be the cause of the freeze. I know that I witnessed it happen few times during my own tries. Daz Studio doing nothing at all (the CUDA meter being at 0%) for around 15 minutes, I kill Daz Studio, and when I try to render the scene again, it works fine.

Another possibility is to set the render setting at really low quality, for it to be fast enough, then hide this or that in the scene, to find what asset can be the cause of the freeze/slowdown.
To turn the render setting at really low quality you can use the attached Daz script if you want.

Looks better at SubD 4 but works even with 2, unless you rendering extreme closeup.

Exteme close up is a bit much. Some skins are not balanced the same way.
That said it's rather rare far I know (pure focus on HD scult).

I believe that at least one of the batch render scripts restarts daz between each queued scene, precisely to help avoid out-of-memory or "daz weirdness" crashes.

Get GPUz and start the iray preview before you render
check the memory usage so its within those 8gb? of gpu ram

if its close use mid to high for the texture compression method

Render Queue 3 offer the option, but you have to set it yourself. I usually set it to restart Daz after 10 or so renders, depending on how many there are.

For AVNs, I'd recommend against using them regardless. I feel like HD morphs are largely reserved for one-off renders.

It's not the OOT hair bug, right?
Are the characters in question using OOT hair?
(Although I would assume you have previewed in iray before commiting to render though... and if that worked it probably isn't that bug)

If so you could try to select the hair and open it in the Surfaces tab. Scroll down to Transmission Color and set it to None. Save the scene. That should clear the problem if it was the OOT bug.

I'm putting my money on this guy. In the last few months, these kinds of issues come down to OOT hairs 86.3% of the time.
