This is a Cycles render integration into Softimage. This version is a second generation of the addon. It was completely rewritten from scratch. Works with Softimage version 2015 SP2. This is a latest version of the Softimage, so, no reasons to use other ones. Landing page of the addon is here.
Download compiled and packed version of the addon from the release page, and install the addon as usual. The addon requires nvcuda.dll library, installed into system. If you have an NVIDIA GPU, this library is already installed. In other cases (if the GPU is integrated or has a different architecture), simply download this file from here and copy it to the Sycles\Application\Plugins\bin\nt-x86-64 folder.
Repository contains solution for Visual Studio 2019. This is minimal version for using Cycles render pre-built libraries. For compile addon from scratch some third-party libraries are required.
dst.zip and dll.zip archives from heredst.zip and place the folder dst near src folder in the repository directorysrc\SyclesPlugin.sln solution in Visual Studio and build it.dll files from the archive dll.zip to the directory Application\Plugins\bin\nt-x86-64 and place it near the compiled file SyclesPlugin.dllIf there are some issues or questions about using the addon - create a thread on Issues page. It's possible to use old documentation for the first generation addon (Sycles 1.12) from here. Also official Cycles render documentation can be helpfull.
All versions of the addon has the number 2.x.y. The first number is always 2. It means the second generation of the addon. The number x starts from 0 and should be increased every time the Cycles render engine libraries are recompiled and updated. If x is changed, then y starts from 0. It should be increased every time when addon code is updated for a given version of the Cycles libraries.
