Works fine in the instant meshes bridge sop, it uses subprocess to call instantmeshes.exe. Is this a mac specific problem?

There's no way to display a 3D texture with that much resolution in the viewport. The default max 3D texture size is 256^3, which is a small fraction of your volume's 4058 voxels along it's longest axis, that's why it looks bad in the scene viewer. If you have a lot of vram, you can try going to 512^3, but it probably won't look that much better.

The scatter sop takes a texture input to determine density if you scatter in uv space. A simple setup is to use the copnet to create a quad with the aspect ratio and uv's to match your image. Convert to polys and connect to the scatter sop. Set it to scatter in texture space with a density texture. You may need to increase the density scale considerably to see anything. Be sure to disable scatter relaxation. This will ruin the sharpness of the texture, and not to mention slow it down. Also make sure to add ‘uv’ to the list of vertex attributes transferred by the scatter, if you plan on reading color information from the texture with the points.
