Frequently Asked Questions
Hardware and Software
What are the hardware requirements for Octane Render?
Octane Render requiresa CUDA enabled NVIDIA video card.  An up to date list can be foundhere http://www.nvidia.com/object/cuda_learn_products.html

Ifyou are interested in purchasing a new graphics card to use withOctane Render, the Geforce GTX 260 currently has the best Performance to Priceratio.

Are OpenCL compatible cards supported?
OpenCLis currently not as mature as CUDA.  As OpenCL matures, it isplanned to be supported which will open up the video cards that will beable to be used with Octane Render.

What technology is Octane Render based on?
Octane Render's engine is a custom Cuda implementation, it does not rely on any 3rd party middleware like Nvidia Optix, and as such it can run on older consumer video cards (Nvidia 8000 series and up), instead of high-end Quadro cards that most other solutions and middlewares require.

I'd like to use Octane Render, but i have an ATI video card, or any other non-CUDA capable video card, what should I do?
Currently, Octane Renderrequires a CUDA enabled video card to be installed.  If yourmotherboard can accept a second video card, it is possible to install asecond video card and dedicate the non-CUDA card  for gaming andgeneral display in the operatings system.  The newly added Nvidiacard can be dedicated to Octane Render.  Thecost of Octane Render is low.  The additional cost of integratingan Nvidia GPU into your system is very low compared to purchasing 10 to15 more computers to get equal performance with a CPU based solution.

What are the software requirements for Octane Render?
•    Window XP (32 or 64 bit) / Windows Vista (32 or 64 bit) / Windows 7 (32 or 64 bit)
•    Current CUDA 2.3 Software Drivers (http://www.nvidia.com/object/cuda_get.html)

How can I check to see if I have the software and hardware necessary to run Octane Render?
CUDA-Z(http://cuda-z.sourceforge.net/) is a utility that provides informationabout the CUDA environment that is currently installed.  If itfails to run, the CUDA drivers, toolkit or SDK may not be installedcorrectly.  When CUDA-Z runs properly, CUDA is installed properlyand information about the current NVIDIA card can be determined.

What about other operating systems?
While the current targeted platform is Windows, Linux support will be available soon.

Is Octane Render multi-threaded?
Octane Renderis a new type of renderer that doesn't use the CPU (with the exceptionof handling file management and other mundane program tasks.)  Octane Render completely relies on the GPU for rendering performance.  Therefore, to increase rendering performance in Octane Render, a more powerful graphics card will be necessary, not adding CPU cores.

Does Octane Render take advantage of SLI?
No,but it can use multiple video cards for rendering.  This willallow two completely different architectures to be used in a machinewith multiple PCI-E slots (such as a GTX 260 in the primary slot and a9800GTX+ in the second.)


Availability and the Beta Program

When is Octane Render available?
The beta version will be available February, 2010 for purchase for 99 Euros.  

Why are you selling Octane Render Beta Versions?  
Octane Renderis the first renderer of its kind and Refractive Software is eager torelease this powerful tool.  Instead of teasing users with webvideos, Refractive Software wants to get the power of Octane Render into the user’s hands.

The beta version of Octane Renderwill be priced at 50% of final release cost.  This will allowuser’s to start using Octane Render and enjoy all the benefits of thelightning fast renders and interactivity now, and having a full Octane RenderVersion 1.0  license at a much reduced rate.

If Octane Render is as great as it sounds, why is it so cheap?
Refractive Software could have charged much more for the performance of Octane Renderand sold to fewer people, but in these hard economic times, thatwouldn’t do much for helping out smaller studios and individuals fromhaving access to this powerful software.  By keeping the costlower, more individuals will have access to this power and will be ableto generate more economic growth than if only a few were able to affordOctane Render.

   
The Render Engine

What are the features of Octane Render?
•    Fully GPU Accelerated
•    Fully Interactive
•    Physically Based Materials and Lighting
•    Realistic Camera Model (Supporting Real-time Depth of Field)
•    Un-biased Spectral Algorithms

What is interactive in Octane Render?
In Octane Render,the current view of the scene is constantlyrendering.    As you adjust the materials of yourobjects, you can see the changes immediately on thescreen.   You can adjust the camera parameters and see theresults on the screen.  You can adjust the position of the sun inthe sky and watch the reflections change as the sun moves across thesky.  The interactivity in Octane Render ends the crazy cycle of adjusting parameters and waiting for the resulting render.  With Octane Render, you can work at the speed of your imagination.

Is Octane Render really Un-biased?  How can it be and be so fast?
Yes, Octane Render is a true, un-biased ray tracer that runs completely on the GPU.  Octane Renderdoesn’t sacrifice accuracy in order to provide a 10x to 15x speedincrease over traditional, CPU based un-biased ray tracers.  It doesn’t use biased methods to approximate results.  There areno tricks…it’s just really fast.

Why is my computer so slow when running Octane Render?
Octane Rendercompletely tasks the video card while rendering and previewing thecurrent scene.  This leaves much less video processesing powerleft for the operating system to draw windows and do screen refreshes. This can be overcome by either pausing the render to work withthe operating system at full speed, or by adding a second video card(if the motherboard supports it) and using one video card dedicated to Octane Render and one for all other operating system functions.  


What are the materials available in Octane Render?
All materials are physically based in Octane Render.  The current types are Glossy, Diffuse, and Specular (Glass).  

What types of lighting is available in Octane Render?
Allenvironments that are typically used in un-biased renderers are alsoavailable in Octane Render such as Sun / Sky, Environment Maps and Area Lights.
   
What modeling  software is can be used with Octane Render?
Youdon’t have to be jealous of package “X” anymore because they have agreat render package only available to them.  The power of Octane Render can be enjoyed by users of most modern 3D modeling packages.  

The Octane Renderbeta imports geometry and materials using the Wavefront “obj” format,which most modeling software supports, or via RenderMan(TM) compliant RIB file import.  Once the scene is setup inOctane Render, the geometry can be re-imported without the need to recreate all the materials.

Is animation supported in Octane Render?
Therelease version (Octane Render V 1.0) will include RenderMan™ compatible RIBimporting, which is supported by many animation packages.

How fast is Octane Render compared to CPU Un-biased engines?
Just as it depends on which CPU you use, it depends on which GPU you use with Octane Render.  Speeds  increases of 10x to 15x can be expected over traditional CPU based unbiased engines.

What is the typical workflow for Octane Render?
The scene is exported from the modeling software and imported into Octane Render.  Once the scene is in Octane Render,the materials and lighting are adjusted to the user’s liking.  Therender resolution and rendering settings are lower at this point toprovide maximum interactivity.  Once the scene is ready to berendered completely, the resolution can be increased and the renderengines settings cranked up.  The final render will be complete ina matter of minutes, not hours as is typical with CPU based un-biasedrenderers.

How flexible is Octane Render for scripting?
Octane Render is completely node based which allows for very flexible and complex setups.  Octane Render 1.0 will ship with a scriptable console version as well which will allow even greater control from external applications.

这回犀利了 革了工作站的命
只是这软件够不够好用 而且别的软件跟进后 这家公司就没得混了

河蟹万岁

主要基于CUDA  要是买N卡送软件就牛B了

飞鸟真

费米会很贵吗？quadro贵吗？tesla贵吗？买不起？
现在重仓nv股票，几年后买几块卡玩眼皮都不眨，可惜国内不方便买美股，肥了在国外的兄弟。
