At some point we'd like to port all of Octane over to the new framework, but until then, 2019.2+ can start to leverage AMD/Intel/Apple devices to offload some portions of the rendering work.

Octane 2019.2 and later will ship with significant portions of the engine moved to this new framework, but you will still need a CUDA device (even if it is a network slave) to run the other 60% of Octane still in CUDA.

Currently we are porting Octane over to a new framework (RNDR SDK) that cross compiles to Metal/Vulkan/CUDA to support all GPUs on all platforms (even iOS). We stopped AMD CUDA development around 3.06.2 (although we yet release AMD OctaneBench 3.06.2 for RNDR node testing). But if you do need to, it’s a juggling act between getting the right amount of scattering across all skin materials.How come AMD still doesn't have support for Octane? ĭoes Octane need to have OpenCL library implemented? Practically, you may not need to worry about this setting too much, for example if the object is distant or if the ears are covered. It is very much a case of trial and error, and an area I still need to work on. It very much depends on scale, lighting, position, kernel settings and so on. Sadly there is no one definitive setting that will work across all objects. -1.0 – light backscatters in the direction it came from.1.0 – more light continues to travel in the direction it was originally traveling.0 – light scattered the same amount in any direction.This controls the direction the light is scattered: Scattering is similar to absorption, but defines the speed at which light will be scattered when it passes through an object. The image shown here is from the colour picker within octane – a colour set to absorb blue will scatter as red. It took me a while to get my head round this, but essentially the effect is the scattered light will be the opposite of this colour (from a wavelength perspective). This setting defines which light is absorbed faster, in the case of the 3 rd node it’s a green/blue.

The scattered light will be the opposite of the absorption colour.
