Refractive Software® is proud to announce the availability of the beta 2.43 release.
This version needs OctaneLive. You will find your OctaneLive account information in the customer area. You will find an FAQ here:

IMPORTANT NOTE: Regarding CUDA toolkit use and multi-GPU support
During our migration to CUDA 3.2 we have noticed that due to changes to the CUDA toolkit by NVIDIA, our approach to multi-GPU rendering on Geforce products has been handicapped. As a result using more than one GPU for rendering does not offer a speed increase with the CUDA 3.2 releases.
We are rewriting the multi-GPU feature to resolve this issue, also adding some new features, so as an intermediate solution we will be supplying both CUDA 3.2 and CUDA 3.0 solutions.
- CUDA 3.2: Recommended version with better support for modern GPUs (like GeForce GTX 4xx/5xx), which should be used if you are not rendering on more than one GPU.
- CUDA 3.0: Legacy version for correctly functioning multi-GPU support.
Provided below are the CUDA 3.0 and CUDA 3.2 builds for Windows. We will release Linux and Apple Mac OS X builds as soon as they become available.
Please note this version requires you to enter your OctaneLive® license information. These can be found as explained here:

New features and fixes since beta 2.42
- Code: Select all
- fixed incorrect behaviour in node inspector when nodes were swapped
- fixed crash when you deleted a mesh node
- fixed crash when you deleted nested macros
- connecting the preview render target with a different camera changes the camera view - the same applies to all other connections like environment or kernel
- the preview render target node can't be deleted anymore
- changing of render target connections should be now more robust: it's not 100% perfect, but should crash a lot less and if you have changed the connections to a state where the renderer is not updated anymore, you can save the project and reopen it, which will fill the gaps and make the renderer work again.
- CUDA driver and runtime versions are now displayed correctly (interpretion of return version number was incorrect)
- right mouse button doesn't select a node anymore
- fixed overflows in film buffer -> no more cyan or purple spots on superbright area lights
- connections of the output pins of the currently selected nodes are highlighted as well as the input pins they are conneted with -> input pins of picked materials are now highlighted
- changed OctaneLive authentication flow: we differentiate now between incorrect credentials and connection problems. if a connection problem occurred, we retry after 10 seconds and display a countdown dialog while we wait (can be cancelled). incorrect credentials will lead to the OctaneLive account dialog. this should fix the major issue of OctaneLive in the animation workflow: sporadic connection problems made OctaneRender display the OctaneLive account dialog and wait for user input.
New features and fixes since beta 2.41
- Code: Select all
- fixed black borders during sub-sampling render mode
- fixed thin vertical lines in multi-GPU mode (that was a good one :) )
- fixed reproducible crash, when an internal material node, that has been selected by the material picker, gets replaced by an external material node
- fixed update of camera node, when camera is updated
New Features and fixes since beta 2.4
- Code: Select all
- higher precision for edit fields of float texture nodes (for example roughness of specular materials)
- made alpha channel output work for all resolutions
- made alpha shadows work for mesh emitters, too
- (internal) during the construction of a new project, all split and work panes got added twice to the node graph. that's fixed now.
- added project file name to window title bar
- the current project directory and file name is now updated in all situations (which wasn't the case before)
- 2D viewport zoom/pan while viewport is locked is possible now
- fixed not working inverse zoom
- fixed placement of zoomed viewport to lock correctly to the mouse
- MTL material names are now made unique while loading, non-unique material names in OCs files caused a lot of confusion while loading and then later incorrect behaviour in Octane
New features and fixes since beta 2.3 v5
- Code: Select all
RENDERER
- Black vertical areas on GTX460 and GTX5xx cards is fixed.
- Alpha Channel output support
- Alpha mapped material now cast correct shadows. (Only pathtracing integrator currently, can be enabled/disabled in pathtracing kernel options. If not needed, switch it off for slightly better performance)
- Gradient Mapping Node for more advanced procedural materials
- Shift lens option with configurable X and Y offset in camera (Usefull for architectural renderings)
- Opacity channel value of zero could crash the engine, which is now fixed.
- Crash when creating a new file while activating a node is fixed.
- Display of correct amount of cores used for GTX460 and GTX5xx series cards.
USER INTERFACE
- Node Graph Editor can be panned to edit large node networks
- Tooltips that display nodepin names when hovering over them. Hover with the mouse over the pin icon in the Node Inspector and you will see the name of the input pin.
- Node Inspector panel is compactified for better use of screen real-estate, and uses a fixed width on all displays.
- Render Preview Configuration preview buttons have been moved to the top of the Node Inspector panel to make better use of screen real-estate.
- Lock button to lock renderviewport during rendering.
- OBJ MTL use of textures with alphachannel will create an alphatexture node on the material's alphatexture channel.
- Bug where some nodeconnections are not drawn is fixed
- Nodepin connection bugs fixed which would cause assert errors and crashes
- Moving a node in the node graph editor rebuilds the node system and restarts the render process, is fixed.
- Recenter view button added to reset the image view in the render viewport, and the pannable nodegraph view.
IO / CONTROL
- Material relinking and emitter relinking from plugins bug is fixed.
- Image, FloatImage and AlphaImage textures now have a reload button to release an image in use.
- command line -g flags causing a crash is fixed.
- Selecting a different device in the CUDA device info dialog, throws an assert, is fixed.
- load 2 mesh nodes, select one then other causes crash, is fixed.
- Command line width and height flags maximum raised from 4096 to 8192.
How to connect to OctaneLive® through a firewall/router
If you have a firewall/router, and you cannot log into the octanelive® service (e.g. the server cannot be contacted), configure your firewall or router to allow outbound connections to the URL named 'live1.refractivesoftware.com'.
CUDA drivers/toolkit requirements for Windows
To use this release you should install the latest Nvidia drivers for your GPU. It was built and tested with driver versions 260.99 (GeForce), 266.45 (Quadro) and 266.58 (GeForce).
CUDA driver requirements for Macintosh
The CUDA 3.2 release was built and tested with CUDA Toolkit 3.2.17. To use it you should install the latest NVIDIA drivers for your GPU, plus (in that order)
- the NVIDIA CUDA Toolkit 3.2.17, http://developer.nvidia.com/object/cuda ... html#MacOS
- the NVIDIA CUDA Driver 3.2.17, http://www.nvidia.com/object/macosx-cud ... river.html
CUDA driver requirements for Linux
The CUDA 3.2 release was built and tested with CUDA Toolkit 3.2.16. To use it, you should install the graphics driver NVIDIA-Linux-x86_64-260.19.29 or later, plus the NVIDIA CUDA Toolkit 3.2.16 which you can download from: http://developer.nvidia.com/object/cuda ... html#Linux
The CUDA 3.0 release was built and tested with CUDA Toolkit 3.0. To use it, you should install the graphics driver NVIDIA-Linux-x86_64-260.19.29 or later, plus the NVIDIA CUDA Toolkit 3.2.16 which you can download from: http://developer.nvidia.com/object/cuda ... html#Linux
OctaneRender for Linux was built and tested on CentOS 5.5 using GCC 4.1.2. Due to that libstdc++ must be of version 4.1.2 or higher.
