OcDS 2.1 PRE RELEASE 5th

[Veneris]

Is your render larger than your video card's memory? My understanding is that if your run out of memory, Iray will default back to CPU only.

I just add to Victoria 6 with no clothes and with a shoulder-length hair. Nothing complicated. Just that, nothing more. I also tried with OCDS in with the same and the same resolution and OCDS <--- in 20 seconds creates the render. In the toolbar memory usage in OCDS use shows that only 4% of 12 GB. How could I have spent using the Iray? it's crazy.

The GPU is enabled Iray. Enabled and disabled the GPU, with Iray shows me the same long rendering time. Maybe it is a programming error or my computer is wrong.

Understanding that your GPU is enabled, unless they changed it, you still need to disable your CPU, or it slows down to (pretty much) CPU only rendering speed while utilizing the GPU (was a known thing, so may have been fixed for stable release, unless it is intentional for AMD users or something).

I already did that, only the "GPU" the scene described above (Victoria 6 naked with hair, face close up) took 4 min. 2 seconds. 1920x1080 IRAY. With the "CPU" and "GPU" It took 4 minutes 12 seconds. 1920x1080 IRAY. I'll upload a video later.

A simple scene with V6 & hair shouldn't take that long even in iRAY. There appears to be something wrong with the DS 4.8 settings because your Titan should render using iRAY at a much faster speed than CPU. The fact that they are rendering at nearly the same speed probably needs specialist iRAY help which I think you're more likely to receive on the DAZ forums. Perhaps someone there can troubleshoot the problem a lot better than many of us OcDS users can here?

The hair could actually be causing a problem. There is a known unfixed bug that causes issues in Iray when layers of geometry that use opacity maps intersect, as you'll find on some hair models. Most of my hair models seem to work fine though.

In general, I've found Octane and Iray to be close enough in rendering speed that I didn't notice a difference when I switched from Octane to Iray a couple months ago. (I never timed the renderers head to head, but if there is a speed difference between them on my Titan it isn't noticeable enough to affect my workflow.) The lack of crashing and better integration of Iray immediately began saving me time and lead me to make the switch, along with the presumption that all future DAZ products will come packaged with shaders ready to render in Iray which should save me a ton of time setting up materials. I've spent hours trying to get all of Stonemason's Urban Sprawl 2 materials set up properly for Octane, and there are just so many nodes in a set like that that it's a major headache and I never fully finished. (Simply organizing that many nodes in Octane is incredibly daunting before you even do anything to them.) Knowing that when Urban Sprawl 3 is released later this year it'll have Iray shaders already meticulously set up by Stonemason himself... well, it'll be beautiful.

Though I'm currently using Iray, I check in here just about daily hoping to see an update to Octane (or maybe some official news) which might give me a reason to fire up Octane again. I'll go with whichever software does the job best, so I'd love to see the Octane DS plugin be better than Iray, or at least a reliable stable companion to it when it is the better tool for a certain job.

Any future third party DAZ plugin renderer that would challenge the integration, speed, quality, and cost of Iray would have to be a totally next level of technology, akin to how much better Octane and Iray are than 3Delight and Reality. Being only marginally faster than Iray won't be enough to make up for the weaknesses in stability, support, and integration that comes with any 3rd party plugin renderer. A future Iray replacement would have to be another game-changer, doing something radically innovative that Iray can't be made to do, which I can't even currently imagine. Perhaps something which takes unique advantage of a class of computing hardware that doesn't yet exist.

As you point out the big draw of iRAY is the integration with DS and the ready made lighting and materials designed specially for iRAY. There is little possibility of OcDS being able to compete in this area apart from the RedSpec skins. Regardless of whether OcDS is slightly faster at rendering than iRAY this will probably be offset by the extra time it takes to set up lighting and materials when using OcDS. Many who use DS depend on content to create their scenes - this makes scene building faster so content designed for iRAY is going to make it very popular. I agree that unless OTOY can come up with some feature that's a game changer then DS users are unlikely to turn to OcDS.

If the new OcDS plugin is eventually updated to v3 then the announced possibility of combining DS scenes and animations with scenes and content from other software would be great but how this might work in practice is open to question atm.

After I've done this I assume I need to make a new shortcut on the desktop to DS 4.7.exe in the new folder?

If you wish to. It's just a matter of convenience. Alt-drag .exe from Explorer to Desktop is fast way of making shortcuts.

Once I've done this can I then just install DS 4.8 over the original version of DS?

Exactly.

The installation info for DS 4.8 says that starter essentials content needs to be updated. Will this affect the DS 4.7 copy?

It depends on where did you install (if ever) the updated content for the 4.8 betas. From what I see in forums people installed it into private content folder of 'public beta' that is not mapped for release version and when they upgrade the content 'disappear'. If that's the case you may install 'Iray shaders and lights' package (from the beta, DAZ delay release due to 'some internal problems' ) via DIM in one of your 'official' content directories or add content directory from beta to release version. Personally I just install everything that comes from DIM into single content dir so all my Studios have it mapped simultaneously.

Hmm, when iray switches to CPU mode usually there are some lines in log file that explain why this is happened.

The 'intersected transparency bug' is still not fixed, but it hit only some of the hairs, usually switching the hair to similar one helps (I experienced this only once, but with my main character , with 'Alice' ponytail, switched to smay's 'Stalker girl ponytail')

Actually it could if only the material presets will work reliably in OcDS. Before iray appeared many artists did their product previews in Octane, so they could release shaders they used. But with the current state of things doing so would only decrease the total value of product and add to customer's anger against OcDS

You can already do this with Alembic but I suspect Otoy will push their ORBX format for that task.

Stonemason's 'Streets of old London' is relased 'in celebration of Iray release', all previews are rendered in iray and the product still doesn't have iray material presets (at least not mentioned on product's page). Marketing

Edit: And it seems that Urban Sprawl will not be released this year (wait for it too) - http://www.daz3d.com/forums/viewreply/820844/
