Yeh I was looking into Octane before coming across this useful thread but now am considering Luxrender also. Do you think its worth saving a lot of money and just using luxrender rather than Octane? Octane looks good but its very dear and am wondering if the extra 300 or whatever dollars would REALLY be worth it?
Also anyone know when reality 3 is out? its taking forever.
Reality 3 for Poser has been out for a while and Paolo C. who is the developer has been working with a few other programmers and testers on Reality 3 for Daz Studio. The progress has been posted on the RDNA forums and at preta3d dot com, it’s “mostly” done but no one has publicly been given an ETA as to when it available. At that aside Paolo has been really on top of troubleshooting, maintaining and listening to suggestions on this product and I highly recommend it if cost and Nvidia GPU horsepower are a concern.
K cool I will look forward to it coming out. Is Octane much better than Lux ender generally speaking?
I have both, and since they are both unbiased render engines, the results are very similar. The biggest differences are the speed and resource limitations. If you usually make larger more complex scenes, then Octane may not be a good fit due to VRAM and texture slot limitations. If you tend to use modest scenes (say 1-3 figures), then Octane may be a great fit. Personally speaking, I don’t have a bit of buyers remorse regarding my Octane purchase. The only “remorse” I have is when, due to either scene size, content compatibility, or other “restrictions” (like contest entries) I have to use another render engine.
The speed of Octane is amazing, not only for final rendering, but also for scene and materials setup. The almost instant feedback I get with Octane really improves my workflow and overall render quality (I’m a test render-oholic). I used to measure render times in hours, a 1 hour render was fantastic, a 2-8 hour render was great, and a 12-24 hour render was common. With Octane my final renders are typically measured in minutes (I have done one 14 hour render), with final output image sizes typically in the 3000+ range.
A long render for me with Octane is a couple of hours. A long render for me with Lux is when it goes over 18 hours (I’ve done 70 hour renders). The results in either one are very comparable. It really depends on if you can work within the memory constraints that come with pure GPU rendering. I wouldn’t recommend using a card with less than 2Gb at the bare minimum. 3-4Gb is much better. You can get a card that will do extremely well with Octane for around $200-270 (3-4Gb RAM and 900+ cuda cores),
To get an idea what can be done with good texture management, the attached SiFi image took just under 2Gb of VRAM (just having fun, was done for a contest) I would guess it has at least 150-200 materials. most are using shaders without unique texture maps. It used 44 color textures, and 8 gray scale (bump), so I still had room for another fully clothed human figure, or other stuff with 20 color slots and 8 gray scale left (with a Kepler based card you would have room for a little over 3X more textures than what I have in this scene). It took about 30 min to render, and it has a ton of reflective surfaces, and the large window is architectural glass. This scene took about 5Gb of RAM in DS, so the amount of VRAM required by Octane will be less much less than the RAM consumed by DS.
A couple more examples.
This post shows Faveral’s Medieval Docks, which is pretty big. A “straight out of the box” render in Octane, done in 2 min. I was just seeing if the scene would fit into Octane in response to a question, so it’s not and artistic render, just a quick example of rendering a scene with no mat/shader work at all.
The image in the link below was rendered in Octane via the DS plugin. Took about 40 min. at 2500x3000. I really liked the way the lace turned out on the top. Unfortunately it’s a bit difficult to see, even in the “full size” view in the linked image, so I attached a higher resolution sample here. Transmap lace like this always brings DS/3Delight renders to an extreme crawl, No post-work on the image other than re-sizing and adding the sig.

Here is one of my best Lux renders, done with Poser & Reality 3. it took 70 hours, but could have been faster had I optimized the scene a bit more.

One other thing to note is that if you decide to get Reality or Luxus, a lot of the lighting and scene optimization techniques that you learn are easily transferable to Octane. So you could use LuxRender now, and if you decide to, get Octane later, and you wouldn’t have to re-learn everything (but there is still a lot to learn with either one).
Bottom line though, you can get awesome jaw dropping renders out of DS/3Delight or Poser/Firefly. Utimately, what you use really depends on what you feel most comfortable with, what you want to do (render), and how much you are willing to invest (both in time learning and money).
