Whenever I press "Simulate" or "Preview" inside Ornatrix Dynamics modifier it tells me that PhysX SDK cannot be initialized.
Ornatrix uses PhysX to simulate the hair in its Dynamics modifier. For this to work you need to install the PhysX driver software that is compatible with the version of PhysX used inside Ornatrix.
If you have an erlier version of 3ds max than 2012 and need the PhysX system software to run PhysX you can use the following link. Please download and install this package, which will ensure compatibility:
PhysX_9.10.0513_SystemSoftware.exe
If you are having compatibility issues because another software installed a different version of PhysX (Thinking Particles, Rayfire, Hairfarm etc) the most important thing to check is that you have compatible PhysX dlls. Ornatrix uses the version of PhysX DLLs which come with 3dsmax 2012 SAP and do not require a driver software installed.
The version of PhysX DLLs used in Ornatrix 1.8 is 1.8.3.17 for 32-bit Max and 1.8.3.36 for 64-bit Max. If you get PhysX SDK error the chances are that you have the wrong version of these DLLs present inside the root directory of your 3ds Max installation. This could be caused by other 3rd party tools installing their own version of these DLLs.
Please download these correct versions and place them into your 3ds Max root instllation directory. Back up your previous DLLs first!
