iRay Progressive Render Settings - Should Time Limit be in Hours?

The max time units in Daz Studio are seconds. I suspect that seconds are the internal Iray unit. As such, that allows people the greatest flexinility in their settings. Also allows Iray to do interget math for the counter, if that matters.

Since hours /minutes is pretty basic, I'll assume that you had some bad typing in your message, Still, might be worth checking your settings to see what number you input. 18800 seconds is 5.2 hours.

 

In the end, to me this doesn't seem like an issue. It isn't a setting that I personally see much need to constantly adjust. Granted my GPU has a lot of CUDA cores, but the default 7200 second limit has been more than sufficient.

Hi,

I think the major problem is the default limit. Most renders don't even reach 10% after 2 hours.

If I don't forget that issue, I set time and samples to the max possible value. That way the render runs long enough to gain good quality. And I can stop it manually, if I think its good enough for my taste.

That hasn't been my experience. Phot Studio style renders at 4500x3000 are completed in less than the 2 hour default limit. Even so a lot of renders are looking really good at 60% as well.

What does seem clearer given all the forum traffic is that render times are really hardware dependent as well as really dependent on the scene. Not trying to insult anyone, but I have a feeling that a lot of folks are trying to treat Iray like its a slightly different 3Delight when in fact it is a completely differnt approach. I should qualify my opinion in that I'm a long time hobby photographer so "real light" makes more sense than 3Delight to me.

The beauty is that anyone can use whichever choice works for them.
