...OK as I mentioned on another thread, seems my beast has met it’s match…

...in the form of hair content.

Reconstructed a scene I tried years ago on my old system which used the Mentha Piperata character for A3 set in Stefan’s Urban Sprawl with a couple palm trees, and lit with LDP2.  Well once it got to that frizzy hair, it would crash & burn after running out of memory on all those transmaps.

The new scene uses Urban Sprawl 2 the palm trees several vehicles and is lit with Cloud9 (as LDP2 does not work in 4.5)

Based on what I have seen so far, I figured it might be slow going but still felt, maybe 25 - 35 min would do it.

Wrong.

After 1 hour & 28 minutes, the scene was pretty much complete…well…except for that hair which maybe occupied 2 - 3% of the entire viewport.  There around her face, something like two dozen render buckets had yet to fill in (the process monitor showing 98% complete).  Ended up cancelling the remainder of the process after another 25 min as it was going on 03:00.

So restarted today, dropped the bucket size to 8 and reduced the trace depth to 2 (default) and set if off again. So far, doesn’t look like much of an improvement as all 8 processor threads are running at 99 - 100% and at 35 min in only at 15% complete.  Once again, there is the same pattern of unfilled render buckets forming around her face as there was last night.

This character came out well before there ever was a 64 bit version of the Studio app or Poser so I wonder how anyone was expected to render this hair with ray tracing turned on while having only 2G of memory (TM is indicating between, 3.55 and 3.65 G being used) and maybe four CPU cores total.

Are you using the presets? If so, the light is created to the right of the default camera with a high vantage point. The Sky also emits light to emulate atmosphere. Remember, Luxus and Reality both use the same rendering, it’s the setup which differs. Check the position of your lights and the type. Remove any unnecessary lights as well, as Luxus will attempt to convert any visible lights in your scene into Luxrender lighting, which likely won’t give desirable results.

Actually, it’s my fault in my part.  I used a millennium environment backdrop which casts a shadow which makes scene uneven.

I’m trying to figure out how we can get light to pass thru unaffectedly.  If you know how, please share that to us. smile

Thanks!

...does anyone know the steps for turning off ray tracing for a selected item (like hair) in UE? The UE help files will not work as my workstation does not have a net connection.

Whichever artist did it may have either had an uber machine, only used Poser, or created it in another program and didn’t bother testing it in the program it was meant for. It seems there is quite a lot of overcomplicated hair around, as Artini showed. There are texture packs available for the hair we were using.

It’s not in UE where you do it, it’s actually UberSurface, you select the hair and load the UberSurface shader, then you can make the necessary adjustments.

CHEERS!

I have made a test render of Aiko5 with Mentha Piperata hair in LuxRender via Luxus interface from Daz Studio 4.5 Pro.
Just after 7 minutes of rendering the image begin to getting better.

I can’t quite tell what the hair is supposed to look like at the moment.

In other news, Reality 3 for Poser has been released. It could be another 2 months before DS gets it, meanwhile Luxus steals a march!

Most hair stuff is covered Here the rendering part is close to the bottom of the page.

I confess I’m slightly less excited about Reality 3 now that I’ve got Luxus. My main reason for wanting it originally was addressed by Luxus (Skin volumes) and I have a feeling that much like Reality 2, it won’t keep up to date with the latest Luxrender additions. Looking at the previews, it seems it’s still very much a top-level editor without access to all of the underlying stuff which can make the magic happen.

Still, maybe it will surprise me. I hope it does.

Yeah, if I were to invest it would be in Luxus.

..Thank you.  I knew it had something to do with UberSurface but forgot the exact steps.

...followed the instructions and 12 minutes later…

This scene idea has been on hold for nearly four years now, just couldn’t do it on the old system with the memory limits.

Niiiice!!

I get the horrible feeling trying to do something like that with mine would probably kill it! That’s one mean system you’ve got there.

...thank you.  Always loved that character.  Kind of the quintessential “flower child” (though I think she’s supposed to be fey)

Used the Mentha top and the Hippie Girl jeans for Aiko3.

Beginning to find the AOA’s Fog Cameras really useful for “big city” scenes.

Is that what is creating the depth?
