Using a small laptop, specs described, looking for tips on quicker 4.8 Iray renders.

smtelephone_cb7254b03a

here goes… I am using an Acer Laptop model number E1-510P-2671. Running Windows 8. This has an intel celeron quad core processor N2920 (2M cache, 2.0 GHz), Intel HD Graphics, and 8 GB DDR3 L Memory. Yes, I know this computer has no right running daz3d at all but i just cant afford to make a good desktop right now.

Can anyone recommend a good rendering setup with Iray for 4.8 for a low end laptop? I am looking for a render time under 3 hours but with nice Iray quality. I tried using the optix checkbx for an added boost but the render just sat at rendering for three hours while i went out. It would be nice to be able to render in 2560x1440. Thanks for any help!

I don't think *my* laptop could do a 2560x1440 iray render to finished quality in under 3 hours on the CPU, and it's WAY more powerful than yours. I did an 800x800 or so scene with just a few things in it using Luxrender and it took 4.5 hours to get to finished quality on the CPU (GPU, it took 20 minutes).

I'm frankly shocked your Intel HD Graphics can even *do* iray. Iray is an nVidia based process, so as far as I know, to get it to work correctly you need an nVidia graphics card. Intel HD is not even a graphics "card" - it's just an integrated chip on the motherboard. It'll do a fine job with stuff like YouTube videos, but iray? I wouldn't even want to try it.

I think with your specs, you are going to be much better off doing 3delight, and even that will probably be fairly slow for rez as big as you are asking for.

Iray renders okay, if not a little slowly, with just use of the CPU. Of course a Cuda Core Nvidia card will speed things up quite a bit.

So with what I have right now just use 3delight? Idownloaded Luxrender, is that worth trying? What about 3delight with macro skin? i heard its pretty nice looking.

Well, I would say do a test. Make a small scene, a character you plan to use and a backdrop and a couple of props. Then choose the # of lights and angle you plan to use in a typical scene. For instance, if you plan to use 3 point lighting, then use that. Do a 3 point light setup in iray and render it, and time it until done. Then do the same thing in 3delight. Don't try to get the scenes to look exactly the same, just do it for timing. See what a difference you get.

For me, on Luxrender, CPU only, on my high-end laptop, it's 4 hours to get a scene to render to what I would consider "completion". Same scene, same # of light sources, in 3delight, would take 4 minutes. IMO it is no contest.

Now, with my machine I can do GPU renders and that cuts the render time to something more reasonable. But honestly, the effort it takes to convert every single surface in the scene to something usable in Luxrender, when I can just load them in as defaults and render straight-away (most of the time) in 3DL makes Luxrender/Reality a non-starter at this point. It's not like all the DAZ products will come with pre-configured shaders and surface textures for Lux.

Ok i will do that, I typically use a three point spotlight setup. For the spotlights, should they be photometric or regular in 3DL? In iray i have been using photometric.

My experience is that Iray is faster than LuxRender in most cases.
IRay using CPU only is faster than 3Delight using the same render settings as IRay has by default. IRay is like rendering in 3Delight with UberEnvironment2 set to Global Illumination and Maximum TraceLevel set to max.

Usually a laptop will have problems rendering compared to a desktop box as most laptops either use m(obile) versions of CPUs, which among other things drops the speed of the second hyperthread per Core down to like 15% to avoid overheating, or use desktop CPUs with the effect that they might overheat with the sustained high CPU usage renders are.

When I say problem, I mean compared to a desktop machine with good cooling and desktop or server grade CPUs.
