If you press the Advanced button during the next step, you will see the full list of customizable settings:ĭirectories – Please check if the default folders are correct. Click the I accept the Agreement button to proceed.ģ. Please take a moment to review the agreements. You will be presented with the Phoenix Licensing Agreements. Upon the start of the installation, Windows may ask you for permission to run the installer with administrator privileges. For more information, please refer to the Uninstalling Phoenix page.īefore running the installation, make sure your Windows account has administrative privileges and the dongle is not plugged in. If you experience problems, you can manually uninstall the previous versions to perform a clean install. This will allow you to seamlessly upgrade from older versions of Phoenix. The Phoenix installer will automatically remove any previous installations. If you plan to render your Phoenix simulations with V-Ray, and V-Ray is currently not installed on your machine, please make sure to first run the V-Ray installer before running the Phoenix installer. Here is a short step by step guide by Microsoft on Adding an Exclusion for Windows Defender. It may also be beneficial to add an exception for the Maya process (maya.exe under Windows). log) or the log file directory (accessible through the Phoenix Preferences) to the exceptions of the Anti-Virus software. You may also add Phoenix log file extension (. Since cache files are often hundreds of Megabytes or more, this could cause the simulation to slow down several times.Ĭonsider adding an exception in your Anti-Virus software for these file formats. vdb as a potential risk and consume significant processing power to scan them. On some machines, the Anti-Virus software may treat Phoenix's files. GPUs are currently only used for the GPU preview of fire/smoke simulations.
Turning off the preview for all grid and particle channels during large simulations could also help speed up the simulation. Simulating on one NUMA node is often faster than waiting for multiple nodes to synchronize.īoth large and small simulations take significant time just to write the cache files from the simulation and to read them back for the preview, so good storage speed can help decrease simulation times up to 30%. Also, NUMA and multiprocessor architectures do not perform well with Phoenix. Processor speed is more important than core count. The entire simulation grid gets processed tens to hundred times per simulation step, so the bus speed is the bottleneck in most simulations. Phoenix transfers huge amounts of data between memory and the CPU.
