Why is Daz Studio 4.8 so slow rendering? I made what I thought was a simple scene, it did have the water grotto in it, and V7. Just the two things. It took 4 hours and it still wasn't done. That's with the default size of the image. I am used to Poser's rather speedy rendering. I have the required PC according to Daz specs: Quad core 3.3 Intel i7, Nvidia video card with 4 gigs of RAM, and 64 gigs of regular RAM. My computer is normally very fast. Even Vue renders fast. I can't believe the suggestions made by Daz. "Try different brand of RAM, get a new PC (WHY?) I can't even do test renders in Studio without it taking hours. In Poser 11 and Poser 2012 Pro, it takes minutes to render entire scenes with 6-7 Vickies and M4 like I did with my holiday dinner scene. The final render in that one took about ten minutes, if that. Daz Studio is very frustrating. Can I speed up my renders? It does not seem to make a difference if I am using the Iray engine or the 3Ddelight engine. Both are long.

Go to Render Settings and switch to 3Delight, iRay needs an High End PC to be fast with an High end Graphics Card and a lot of RAM.

Does the grotto include a modelled sky dome? If so that will be blocking most of the light from the default HDRI environment and making it almost impossibly for Iray to resolve.

I'd say drifterlee's computer meets the High End requirements.

@drifterlee: have ya made sure to at least apply the Iray Uber shader to all the materials in your scene? Maybe there's a 3Delight shader in there gumming up the works that Iray doesn't like? Is there displacement? Iray chokes a little on displacement... What are your Iray settings? Do you have CPU AND GPU checked in them?

RE Uber shader. Good answer LaurieA I been down that path myself and it can certainly turn a snack into a four course meal out of things.

As Rhaseltine has pointed out the early skydomes can give you grief as it blocks out the sun :-). The Grotto water if it is the one I am thinking of in the nature kit has both the 3Delight and Iray versions

Either way With early skydomes I found it limiting because some of my Dreamland Model sets etc had great domes which I wanted to use so as a sideline this is worth a peek Here is a YouTube video which I hope you are up with your German language skills although I just watched the footage not understanding a word and it works a treat even if a little lengthy process. DAZ Studio Tutorial any Skydomes with iray rendering in GERMAN

Hi Johnny,

thanks for the link, great tuts in German there, the one you mentioned is not realy German, IMO it's Austrian, lets say a German dialect (sorry dear Austrians).

Well, at least it wasn't Swiss-German. That is nearly impossible to understand.

OT: IMO Swiss-German is no language, it's a strep throat

@Jules53757 There is a difference?

No!

I'm still working on it. I can't often find the render settings. It seems they change with each figure. I wish there was a new -up-to-date book on Daz Studio. I buy things for Daz Studio from Rendo and then I can't find them in the content. Like a new pose set from Ironman. It just does not show up.

PS. What is the ubershader and where can I learn about it?

To find content in Studio is sometimes very tricky as the structure of studio is not so clear as it is in Poser. Sometimes you'll find Poses for G3 located under Presets. The easiest way to find the content is openthe original Zip and search the poses, often under People but not always.

About Ubershader I have only a link to a You Tube vid but it is in German but when you view it in Full screen mode you will see where the guy clicked and you will find the settings in your Studio.

To find content in Studio is sometimes very tricky as the structure of studio is not so clear as it is in Poser.

Cough... Surely you mean easier for you? I Personally prefer DS's methods of handling content storage, where everything isn't a hack on a Pose preset and shoved in the Pose folder. ;) Using both the Smart content and Content library tabs together makes life pretty easy.

In Daz Studio content you can use either the content library or Smart content to find things in your library or both together. The smart content library tab uses metadata and associations to bring up relevant content to what you have selected in the scene and from there you can further drill down by type. The content library tab is closer to the poser library where most things are drilled down to from the top of your content library.

Poses belong in : /People/Figure Name/Pose/Pose Set Name

Ubershader or Iray uber base shader is part of the base Iray lights and shader set for 4.8 and can be found: /Shader Presets/Iray/Daz Uber This folder also has around 50 other Shader examples for Iray including car paint and metals.

Alternatively using smart content.

Poses Select your figure and select poses in smart content and all of the compatible poses for that figure should be displayed in smart content.

Shaders Select your item and its material surface. Then select materials in smart content and Default Lights and Shaders for Daz Studio product and the Iray Uber base should be at the top.

@drifterlee I take it you've ticked the checkbox to tell DS to use your Nvidia card? It's under Render settings and then the advanced tab, the same place you swap between Iray and 3Delight. Make sure your GPU is selected because it isn't by default. You can't really compare Poser Pro 2012 render times to Iray render times as they are completely different engines. Firefly in Poser is comparable to 3Delight, Iray is comparable to the newer Supafly in Poser. One thing I've read about PBR's like Iray is that the more lights the better for speed. Darker scenes will take much longer. But you could always try with just an HDRI background. That shouldn't take too long for a couple of figures.

If I were a betting man, I'd say it's the uber stuff. That killed me the first few tries for me with IRAY. I wasn't using GPU and we are talking hours to get fuzzy pictures on a 4ghz machine, lol.

I would start out deleting any unnecessary stuff, like any atmosphere related stuff. Just load the props. Maybe start with just one big prop. Select each of it's textures in the Surfaces tab and then find the Iray uber Base shader which should be pretty easy to find (I've moved mine, so I have no idea where it was hiding originally). Do a render, then keep adding pieces. I suspect you'll either find the culprit or you'll end up with a complete scene that renders reasonably fast. If the water shaders or some of the more complicated things don't translate nicely using the default iray shader, you will have to learn how to fix them yourself, or maybe like someone said earlier...there might be iray specific versions of the model or it's shaders. Of course, if this is a Poser model, it's definitely not going to be IRAY ready out of the box.

Laurie makes another good point about displacement. You can easily end up with a model that simply won't fit in your GPU's memory if you turn up the # of subdivisions really high (sometimes you have to get them high to reflect the underlying texture's pixel density)...really high isn't really a big number, necessarily. When that happens, it jumps doing to CPU only and can take forever. I'm going to guess this is related to the parameters, subdivision Level, but it's been a while since I played with that... Anyway, I doubt anyone would release a product set high enough to overload a 4 gig card out of the box and it doesn't sound like you changed things...but, it's a good point to be aware of.
