It depends on different thngs. I have 20 minutes renders.
Actually that one I just posted was ready in 20 minutes. I did left it a couple of hours because I was busy with something else anyway, but at 20 minutes looked already acceptable to me, it didn’t changed that much with the extra hours.

Other stuff took a pair of days, but it had water and fancy stuff. I don’t mind long render times myself. I’m usually not in a hurry to get images done, so I take my time. smile

Yeah those are some nice renders. And your postwork is good with the fingers and how they interact with the hip. I’ve noticed that in your renders in the past.

Sometimes I need to have a dozen or so renders in a day, so there are definitely times when speed is paramount otherwise it all results in a fail. Right now I am working on something that I can let render overnight so it’s not biggie, but I still can’t let it cook for a few days.

It certainly depends on a lot of things, and that’s why it’s good to have options.

DING DING Rupaul’s Render Race has a Winah!!! LOL

What’s really funny is that both of the last two renders are D|S 4.5 with Uberlight, not Luxrender or Octane.  The pictures below are Image #1 above in Reality / Lux with enough light power to render quickly (rendered for less than an hour just to get it into the 2K+ pixel samples range, it was clean enough after 170.2 s/px).  The point with this exercise is that you can achieve the look & feel you want if you understand the tools at your disposal, and what they need from your subject in order to give the desired results.  You can create incredibly accurate photo realism with a canvas & paint, or a graphite pencil if you understand texture, light & shadow.

Got to admit I cheated - I saw your post over at rendo - very nice render(s)! Opps - Looks like I outsmarted myself red face

Alex L: While you do have a point, your examples are a bit contrived. It’s much more difficult to achieve good lighting using a biased renderer when your image shows more than a single character on an empty stage.

Try fooling us with a fully decorated interior, and don’t put everything but a figure in front out of focus either wink

I don’t do what I would call realistic images, but I do try to make the lighting create a good feeling of 3D. IMHO all of the render engines mentioned so far are capable of creating jaw dropping beautiful and realistic images. It’s up to the person using the software to get the results they want. I also think doing a true comparison between two render engines is very difficult because materials/shaders and lighting don’t typically translate perfectly (or even well) from one to another.

Below is a comparison of the result I got trying to do my own comparison (image(s) with blue background). The image on the left was done in DS, The image on the right was done with Reality/Lux. I think it’s a perfect example of how user skill is critical to results. I’m learning DS (sloooowly), but have even fewer skills with Reality/Lux. I attribute the great differences between the images to my lack of skills (and a spec map that is too strong), not to the capabilities of the software. I like the DS render better than the Lux render, and just don’t have enough experience with Lux as I do with DS.

The third image was my first attempt with Lux (image with staircase). I think it’s a good example of what an unbiased renderer is capable of doing. All of the light in the image, except for the light coming through the dome (skylight) is indirect/bounced light.  It was rendered with 1 sun light that wasn’t directly hitting anything in the scene.

The second image was done in Carrara (image with grrrl in crystal) - it’s just a simple example of caustics and ray tracing in Carrara with a simple 3 light setup.

Below for some other examples of renders done in DS, Carrara, and Poser.

This is what I think is my best image so far in DS

Great paint shaders! Rendered in Bryce? Got to agree with Rareth smile
Here is a car (with a girl in a swimsuit) rendered in Carrara, lit with HDRI and 2 spots for fill/hightlight (sorry for the links instead of direct image posts):

Yes rendered in Bryce. smile

What I tend to do is import models into Bryce and spend a lot of time swapping over all the material zones to Bryce procedurals.

It’s no trouble swapping the colour to white, but applying Herbie graphics on to a messy mesh using the Bryce DTE or Mat Lab would be a right royal pain in the butt and the model didn’t come with a flat mesh template to UV map one on to… Otherwise I’d be temped to have a go at a flame job for it. cheese

The car looks more real than the girl but the girl is certainly more ****able! zipper
