I saw your original post on the Octane forums, great work! I get around the texture limits with post processing, but it's great to see what can be done with good scene optimization. I am going to have to look into writing some of those scripts for saving Blender scene settings.
As far as the $1500 GPU comments go, you can get 3 gtx 480s for around $600 now, thats over 1400 cores. You would need to invest in some cooling solutions as well, but it certainly doesn't have to cost $1500 to get fast render times.
Thanks again to everyone,
@inkimiaei inkimiaei:I used a texture from cgtextures.com and created the bump and the spec maps, the spec map produces this nice fx
@kathy116 kathy116:Yep, quite a cheap solution but indeed with about 1500 $ for the GPU. By the way the other render programs require very powerful machines with probably a similar price.
@MartinLovstrupJensen MartinLovstrupJensen:I used a photo of wrinkles and repoduced it with GIMP to get this result, so really simple and efficient ;)
Really nice renders! I like the bump maps for the pillows! Do you have any PS tutorial on making those?
It's encouraging to see that it is possible to create this quality of imagery for so little money (granted you have about 1500 $ of GPU in your system. Thanks for sharing.
Thanks for very nice renders and tutorial ... can you explain what was the material that you used for the white floor tiles? how did you made the beautiful dirty spots and the reflection on the floor
Thanks for wiewing and commenting and thanks to Ronen for giving me the opportunity to share this experience.
@sdwhitton sdwhitton:Well the process is really simple, I place each image on a layer and play with the alpha slider to control the mixing, and a bit of eraser for some regions, that's it.
@tomglimpse tomglimpse:yep, GPU rendering is still young and requires some tricks to come out with satisfying results but dispite of those limitations I really enjoy it.
@RobSteady RobSteady:Well it depends on what you are expecting, I'm sure Octane could already be used for production workflows not only for still images but also for animations. Memory and texture limitations are indeed a bottleneck for some projects but I'm really surprised by what a 3GB card can render.
@Ronjart Ronjart:Yep, I used VRay on previous projects and was really happy with it, I probably will come back to it for some projects but it's also part of the challenge to use free products and pushing the limits is also a good way to encourage the free commuity ;)
Great insight and some useful tricks. I especially appreciate to see how you are concerned about your budget by using free programs (Blender, Gimp) and a 99 Euro Render. It's encouraging to see that it is possible to create this quality of imagery for so little money (granted you have about 1500 $ of GPU in your system :)! Especially for freelance artists, that offsets the shortcomings of the octane render compared to a really expensive program like vray.
Great images! What about rendertimes?
I see great potential in Octane but for now there are lots of workarounds a too many limitations to use it as production renderer. Maybe in one or two years this could be a serious alternative to V-Ray...
What do you think about it?
Great article!This is one of the best works i've seen in Refractive (creators of Octane) forums. Thanks for author & Ronen for this article!Overcoming Cuda/Hardware or Octane's own limitations sometimes is a hard thing to deal with. I really like the way You manage to combine HDR in PT with Direct lighting, the end result is beautiful (overall the concept is not new as guys use AO pass to enhance renders quite often, but You're certainly the first one tried this technique in OR =)Hopefuly soon we'll see optimised build for Kepler based GPUs on Cuda5 & some of those limitations (speed, texture limit & available vRam..) will be less tight..Looking way forward, this engine is very promising. & After release of instances we'll probably see more and more of it's usage in archviz.Thanks once more for interesting article!
Hi, lovely images! But still don't get how you comped the two images... Is the sun pass put over in 'Overlay' mode? And the HDRI render colourised to give it that golden look?
