Hi All,

 

Some clarification from Next Limit:

 

 

Maxwell GPU rendering is not currently supported on macOS. For GPU rendering, Nvidia graphics cards with CUDA support are required, and Apple does not sell computers which include these at this time.

If you do have an older Mac model with an Nvidia card, we cannot guarantee you a great experience, because those cards are obsolete and have not been tested.

Should Apple include graphics cards appropriate for GPU rendering in the future, we will likely support these. We are also studying the possibility of supporting third party Thunderbolt GPU interfaces, which may provide a viable GPU option for our valued Mac customers.

 

Also, I think it is important to note that Next Limit has been working on GPU integration for several years. This is an extremely challenging technical work, especially as their goal is to provide an engine equal to the CPU engine, not a limited alternative.

Hello Ben,

 

Besides Multi-light being broken out as a separate application, are you aware of others benefits in v4 for Mac users?

 

Thanks,

 

Gary

Hi Gary,

 

 

  • Multi-light standalone, as you mention.
  • Interoperability with other machines running V4. Specifically, since there aren't any computers available from Apple at the moment that are suitable for GPU rendering, you may opt to purchase or build one or more Windows or linux GPU render nodes.
  • Improved network manager.
  • New plugin features going forward will be in the Maxwell 4 series.

"well, other engines are supporting mac GPU rendering, like thea (which you will find as a plugin for FZ) and octane... the problem is that next limit jumped late on the GPU bandwagon, so they have not much experience yet with coding this type of stuff - which needs higly specialized algorithms and a good knowledge of how to use the CUDA platform. waht you get now is basically an early alpha stage of that engine, which will be refined 'on the go'. also, with the new version, they changed their marketing and abandon a strategy which was their big advantage: in the past you bought a maxwell licence and got plugins for all supported platforms. now you have to pay separately for everything, a way to make more money on the paper, but i doubt they will make more clients like this. also, they abandoned a few 'obsolete' platforms like lightwave(which is definitely not obsolete), houdini and soft image."

 

My point is that new Macs don't support nVidia - old Macs can have nVidia cards or added 3rd party nVidia cards as a kluge and may work. Apple with the Mac has decided to support Open CL which is a more open multi GPU support technology that nVidia's CUDA competes with and although Open CL has potential in the future for mass GPU card rendering no renderer currently supports Open GL.

 

In regard to Thea and Octane, there is really no difference between their support and NextLimits. NextLimit has been working on GPU ( CUDA based ) for some time as demonstrated some years ago and it will improve in subsequent updates.

 

On delays with Thea the reason that Thea ( Solid Iris ) may have slowed is that they have recently been acquired by Altair ( SolidThinking )

new macs support nvidia cards via thunderbolt expansion boxes, you can buy them from a few companies... nvidia has been releasing and promptly updating mac video and CUDA drivers for a long period now for all recent cards and all newer OSX versions, so support is very straightforward. using CUDA hardware on macs is maybe still not so popular in the 3D area, but if you have a look at video editing studios, you will find a lot of them using this kind of acceleration.

 

cheers
