Shape alignment in Arnold Scatter: This new option allows you to align scattered shape instances to the surface based on the shape bounding box. Shapes can be aligned bottom, center or top, or placed on the surface at their pivot point as before when custom alignment is turned off. (C4DTOA-3210)



shape alignment turned off	shape aligment set to 'bottom'

Faster Arnold Scatter viewport: Scatter instances are now displayed more efficiently in the viewport, especially when displaying as wireframe or shaded geometry. (C4DTOA-2250)

Windows 10 or later, with the Visual Studio 2019 redistributable.
Linux with at least glibc 2.17 and libstdc++ 4.8.5 (gcc 4.8.5). This is equivalent to RHEL/CentOS 7.
macOS 10.13 or later.
x86-64 CPUs need to support the SSE4.1 instruction set. Apple Mac models with M series chips are natively supported.
GPU rendering and OptiX denoising work on Windows and Linux only and require an NVIDIA GPU with the Maxwell architecture or later.
- On Linux, we recommend 535.104 or higher drivers.
- On Windows, we recommend 537.13 or higher drivers.
Intel OIDN GPU support is limited to:
- Intel Xe dedicated and integrated GPUs
- NVIDIA GPUs using Turing or newer architectures
