If by fireflies, you mean the red speckles—those aren’t fireflies.  They are a function of the SSS homogeneous volume not having enough samples to clean up.  Volumetrics in Lux require a LOT of samples/pixel to go away.  I’ve only seen you mention how long it’s been rendering, but that’s not a useful metric as everyone’s hardware is different.  S/p is more meaningful, and when using volumetrics, you can easily need 5000+ S/p before things start to look OK.

Ah, I see.  I wonder what fireflies look like then?  At the bottom of my render, you can see I included the statistics line:  At 9.5 hours, I was only at 600.24 S/p, 8.80 kS/s, and 187.52 kC/s with 2132% efficiency.  I know that is a very low S/p for this amount of time.  The efficiency is high, and I have actually had lower kC/s, but usually it is much higher.  What is kC/s?  Guess I need to break out the Lux manual.

I don’t know how to quote two replies in a single post, so I wish to thank HeraldofFire for his response, too.  I am going to try the refine brush to try to get rid of the few “sparkles?” that still remain, or maybe take them out in Photoshop.  I will try the idea with the planes and see what happens.  Thank you both very much.

Fireflies are usually blown out white spots that get larger as S/p increases.  With current versions of LuxRender, they are now quite rare, since a lot of the numerical stability/NaN issues have been fixed.  Also, you responded while I was editing my original reply, so instead of repeating it here, you might also check back a page.

Thanks, again.  And, might I add, beautiful render of the chess board.  I can’t see the noise in the tank on the mermaid pic, but I would rather not look too hard for them.  Rather just look at the sexy mermaid!

First post on here in a couple of years, but wanted to join in the fun. smile

Here’s a recent render of mine, using Poser 9. All in all, I’m happy with the look of the skin.

Check it out at full size,

Thanks and enjoy! smile

Very nice (I feel like Borat saying that all the time, but I don’t seem to have an original compliment).  I really like the softness of the skin around her nostrils and the edges between the lips and the rest of the facial skin.

I’ve been doing some more experimenting with skin and expanded that to eyes and hair.  I think I have finally come up with a formula that works well for me.  I don’t see my renders getting any more realistic than this one.  Also, changing the Sampler to lowdiscrepancy helps a huge amount with the red sparkles I was getting before.  And my renders are complete in much less time, even though the S/p are not very high.  It doesn’t matter to me what the S/p is, as long as my render looks great in the end!  Of course, I haven’t tried this with non-organic materials yet, except for the necklace in this pic.  I have a render cooking right now that has walls, chairs, etc and so far it seems to be good there, too.

Let me know what you all think!

Here is an animation done with Octane Render. Yes, there was a bit of postwork in AE.But a lot of the footage is “as is”.

Just because I may have a strong opinion doesn’t make it any more (or less) correct than any other, just that I feel passionately a particular way at that moment.

I don’t even want to think how long that took to render. Evening doing a simple unbiased render on Lux took me nearly a whole day for just a few seconds of footage.

There are some really amazing renders here, especially those in the past two pages. It makes Octane look really appealing smile

I looks like Cycles might be a good option as well, I’m really impressed with the last image posted by 3doutlaw.

I’ve been playing with Reality 3 and Lux the past couple of weeks, but I’m not even close to what y’all are doing yet. At least I’m finally getting some use out of Poser 2012 (never bee able to get along very well with Poser lighting). I’m getting closer to the results I can get with Carrara now, but my focus isn’t photo realism, just realistic 3D.

The link below is to my second render using Reality3, not as good as the images posted here, but I thought I’d share as I learn. Warning, the image has “nudity”. I really like the way Reality3 handles the conversion of the skin shaders. Lux is great render engine, just sloooowww.

It’s a nice image, but I would consider either doing some work on the background textures or using a DOF on the camera to blur them out. The DOF would be a nice effect and would be easier. The focal point (the girl) is nice so the other should be a quick fix smile

...worked with 2010 on the old system.  Ran pretty well in 32 bit compared to S3Advanced. I particularly liked the ability to render in background mode the Queue Manager as it made best used of the limited memory resourced I had.  I could also use Occlusion and Ray Tracing which in 3Delight would be a quick trip to a crash.

I do hear you about Poser’s lighting system. I find Daz to be much more intuitive and more like working with actual stage lighting. Then there’s the ability by one click to view though a spotlight like a camera for fine tuning. 

I have Reality 2.5 for Daz which will mean an entirely different learning curve with lighting as it approaches the task more from a photographer’s, rather than theatrical lighting tech’s angle.  I messed around with 35mm photography but not at a truly professional level and most of my work was out of doors usually photographing events like airshows, races, kite festivals, etc.  Also going to need to learn a lot more about surface properties, something when I worked with oil paints or picked up the old Richo SLR wasn’t much of a concern other than if I could see it, I could paint or shoot it.

Waiting for the Daz version of R3 so we can get SSS to help with skin tones (and make rendering go even slower).

Gedd - Thanks, I actually tried to use dof on the image, but it’s obvious from the results that I didn’t quite get it right (never used it in Poser before), plus I got impatient and wanted to move on to my next image which is baking right now. I forgot to try DOF on the new image, guess I’ll have to give it a go again, cause as you suggested here, I think it will improve the one I’m working on now as well.
