This should take 750 minutes, or 12.5 hours, to finish rendering everything, assuming you have one machine (i.e., a computer) rendering the project. If you have multiple machines running, increase the Machines count as appropriate. The Total render time will be divided by the number of machines based on the assumption that each machine contributes the same amount of processing power.
For projects where both time and the number of machines is limited, or for previewing and editing scenes, you may decide to reduce the render quality (e.g., by lowering the resolution or reducing the number of samples) to shorten the render time per frame. For this to be successful, use the 3D render calculator to determine what render time per frame will allow you to meet the deadline.
For many commercial projects, the rendering quality has to meet certain standards, meaning that the rendering time per frame cannot be reduced. In cases like these, one way to finish on time is to increase the number of machines. But how many do you need?
To further illustrate how this works with a fun example, let's find the average render time per frame in Toy Story 3, based on some numbers from an Insider video article. We learn here that there were over 77 minutes of animation, consisting of 114,240 frames. Pixar used 117 machines and completed rendering in 1084 days. Each frame took anywhere from 45 minutes up to 30 hours to render, but to more precisely calculate render time per frame, follow these steps:
All three GPUs in this system (two A5000s, one Titan RTX) have a single functional physical NVLink connector onboard (which fwiw are not inter-generationally physically compatible.) Meaning that a maximum of two cards from the same generation may be linked together for VRAM sharing and the like. This means that if you have a system like mine with an odd number of GPUs, there is no way for you to be able to use all of them in a functional NVLink configuration. In fact, the only way to get NVLink to boot successfully is by disabling any not-NVLinked-GPUs on the hardware level (disabling it via Device Manager is sufficient.) Otherwise you get error messages from Iray like this:
Also, as has been reported by others such as PugetSystems, getting NVLink to function properly - at least on A series GPUs (consumer 3000 series GPUs are said to be different...) - requires Nvidia driver mode being set on those cards to TCC. Although, interestingly, this is not effective at preventing the problem of odd numbers of NVLink capable GPUs being in the saystem resulting in NVLink setup failing. Ie. even with the two A5000s phyiscally linked together with an NVLink bridge and set TCC driver mode, and the Titan RTX neither physically linked nor set to TCC mode (driver mode is changeable on a per-card basis under Windows) the errors about failing to establish a link between all 3 GPUs persist. Makes me think there really is some arbitrarily feature siloing going on at the Nvidia driver level. Shocking, I know...
Iray Photoreal uses one CPU core per GPU to manage rendering on the GPU. When the CPU has been enabled for rendering, all remaining unused CPU cores are used for rendering on the CPU. Note that Iray Photoreal can only manage as many GPUs as there are CPU cores in the system. If the number of enabled GPU resourses exceeds the number of available CPU cores in a system Iray Photoreal will ignore the excess GPUs.
Combining the 1660Ti and the 4600H on a Laptop did technically increase iterations per second compared to just a 1660Ti, but adding them together, you'll see the number of iterations if you add them together individually is less, so it's diminished returns. Also being a laptop, I'd never do it. Why? Simple, most laptops will thermal throttle and/or get way to hot to be worth the small extra gains. On this specific laptop, even though the 1660Ti has a Higher TDP about double this CPU, it cools much better, even with it half sharing it's cooling solution. The only CPU I'd consider doing this on is maybe a Threadripper where it has GPU like performance and you had the system RAM to spare.
I have a video that some may find interesting about the second hand market. This fellow pulled a lot of data together to try and see how much scalping has been going on. Now the thing I want you guys to remember is that while the numbers in the video are indeed high, keep in mind that Nvidia has shipped and sold tens of millions of new GPUs over the course of time this data was taken. For example, Nvidia stated they sold 9.1 million GPUs in Jan of 2021. Ampere was just 3 months old! Since that time They have sold a good 8 to 9 million every 3 months, and this is being conservative. All of his numbers are based on the US Ebay, but even so this is the largest 2nd hand market by far, dwarfing all the rest, possibly even all combined. It is like comparing California's economy to the rest of the US, where Cali alone would be the 5th largest economy in the world.
Another thing to put the numbers he gives into perspective, one single mining firm in China was running 485,000 GPUs. They were older RX 470s, yes, but this just shows the massive and mind boggling scale that these mining operations can be at. This was just ONE of them. There are many more.

In the import -export settings I didn't checked the merge points ....Any solution? Other than create separate "groups", because I need to split many polygons separately to keep them as hard surface in daz studio. But now those are smoothed .. and it would be too many work to select edges and set smooth weight manually in daz studio.
I purchased Hexagon 5 years ago, under an email I no longer use. My computer has crashed TWICE since, and when I attempt to use Hexagon (which I've re-installed on my current computer) it requires my long-lonst serial number.
I opened Hexagon for the first time in a long time and got a pop-up asking for a Serial Number. I have no idea where this serial number can be found.Anybody know where I can find it?Thanks in advance - Bill
A single, moderately large left ctenidium (Figs. 4, 7c and 8) terminates at the posterior end of the mantle cavity. The posterior end is fused to the mantle roof. The ctenidium occupied 7.9% of the body volume in the serially sectioned specimen. The gill is bipectinate, densely packed with fine gill filaments on both sides. The filaments are supported by skeletal rods. Sensory bursicles could not be confirmed. Two to three prominent and semi-enclosed blood sinuses are present under the left side of the gill. The blood sinuses in Gigantopelta appear to be static and only present under the gill. There is a complex network of large enclosed blood vessels that run through the mantle tissue (Fig. 5h).
Gigantopelta chessoia is gonochorostic, the level of development of either testes or ovary varied among individuals of each sex. (All known specimens of both G. chessoia and G. aegis were collected in several events in different years but all in austral summer, November-December.) The testes were only observed in specimens that were preserved in ethanol but appear relatively paler than the ovae; the ovary is pinkish-brown. The gonad is largely posterior of the pericardium, except a thin leaf of mature gonad extending to dorsally overlap the pericardium (Fig. 9c). In G. aegis, this extension was not present and the gonad was entirely contained posterior of the pericardium (Chen et al. 2015a: Fig. 7). The gonad is connected to a pouch within the mantle roof (Fig. 5a) via a gonopore presenting as a simple slit on the proximal right mantle wall (Fig. 5b). A pocket surrounds the gonopore and extends along the right mantle wall. Within the mantle-cavity, a cresent-shaped flap opening into this pouch is located anterior to the anus (Fig. 8a). The pouch is located on the left side body; it takes up considerable space and is visible as thicker tissue sometimes containing gonad material embedded within the left side and posterior mantle tissue, tilting toward the posterior where it connects to the visceral mass via the gonopore. The pouch within G. aegis is lined with muscular folds that make the pouch or flap appear extensible, though the direction of expansion is unclear. The gonoduct is not associated with any specialised copulatory organs or appendages, the gonad is well contained within the mantle and there is no penis modified from cephalic tentacles. No external sexual dimorphism could therefore be detected. Each of the individuals examined had only a single type of gonad present. The serially sectioned juvenile specimen already had a sizeable gonad (Figs. 7d, 8 and 9), taking up 11.4% of the body volume in the same position as the adults.
Our descriptions follow the standard ontology proposed by Richter et al. [39]. The nervous system is rather voluminous (Figs. 8, 9 and 10) and occupies approximately 3.8% of body volume in the serially sectioned juvenile specimen, proportionately smaller in adults. Both cephalic tentacles are innervated with prominent tentacular nerves. The nervous system is ganglionic, with an oesophageal nerve ring containing distinct cerebral and pedal ganglia pairs. 2ff7e9595c
