Chaos Phoenix/V-Ray compatibility troubleshooting guide

  • Updated

This  article guides you through the troubleshooting steps of plugin compatibility issues between V-Ray and Phoenix.  Using incompatible Phoenix and V-Ray versions may result in:

  • Crash during rendering;
  • Crash or error upon host-app startup (3ds Max, Maya)

 

Sample Error messages in Maya:
(Messages vary depending on the setup)

Error: V-Ray : There was a fatal error building the scene for V-Ray
Could not create plugin PhoenixFDSim !
The procedure entry point vallocDeclareTag could not be located in the dynamic link library...

Root causes and solutions

Phoenix has separate installations for the corresponding V-Ray version, for example:

Phoenix FD 4.xx.xx for V-Ray Next
Phoenix FD 4.xx.xx for V-Ray 5

Here is how to identify if your issue is due to compatibility - check if

  • The crash during the rendering stage disappears when Phoenix objects have been removed from the scene.
  • The crash during the simulation stage occurs even with a basic Phoenix simulation setup with Volumetric or Liquid.

Solution 1

Make sure the current installations of V-Ray and Phoenix are compatible with each other.  The Phoenix plugin installation should match the V-Ray one, for example:

Phoenix for 3ds Max for V-Ray 5.x  requires the V-Ray 5 version in order to be compatible with it. Other major V-Ray versions like V-Ray Next or V-Ray 3.6 will not work with it.

Here is how to check and verify Phoenix and V-Ray versions for 3ds Max and Maya - they should look like the following:

In case the installed versions are not compatible, go to the Download section and find the  corresponding Phoenix or V-Ray version.



Solution 2

Perform a full uninstall to both of the plugins -  V-Ray and Phoenix, then proceed with a new installation in the following order:

  1. First, install V-Ray
  2. Then, install Phoenix

As mentioned in Solution 1, make sure that the installation versions are compatible!  

Notes

We plan to add automatic checks for plugin compatibility during Phoenix installation in the future.  

Note that the same applies to the Phoenix nightly builds. They Should always match the already installed V-Ray plugin!
