Freezing Issue - possible solution

nicstt

I've noticed the thread with people having issues with Iray freezing.

I had the same issues with the drop box link; it was a 100MB file until I converted it to jpeg

It is 8000x 6667 pixels; I thought at first it was memory issues, but I managed to get my new 970 to use very close to the maximum memory and not freeze, although it might be a reason for freezing, but if you do what I have keep GPU-Z open and set to display memory usage in the title bar, you can monitor that. (Also useful to keep an eye on the temperature.)

I simply deleted all the hair, and tested which was causing the issue; I decided to start testing hair first and I lucked out that it was. The problem hair was the flirty hair: https://www.daz3d.com/flirty-hair-for-genesis-2-females Shame as its one of my favourites

It would also be useful if we had a list of products that we think causes this issue so others can verify and vendors and DAZ can look at why it is happening.

I re-rendered the image (below) with a close up just doing some testing; kinda liked the pose. I also like how the eyes and lips turned out.

This is probably the known issue with multiple intersecting transmapped planes - ivy from the Ivy Generator, or hand made along similar lines, is likely to trip it and so are some messier hair styles.

Thanks for reply Richard.

The thing is, I've noticed that with very low resolution, there is much less risk of freezing.

Checking another couple of hair products and will post results

Aubree Hair ( http://www.daz3d.com/aubree-hair-for-genesis-2-female-s ) will render if it is only 600x500, but even 1200x1000 locks up at iteration 2. After deleting the hair it would render as normal. I tried 3 times to render with the hair and it locks at the same stage.

Miwa Anime Hair ( http://www.daz3d.com/miwa-anime-hair-for-genesis-2-female-s ) also freezes, but at iteration 33, and that is as low as 500x500; it locks at 1 iteration at a higher res.
