You will need to use the Production Build of Houdini that matches your Redshift plugin version.

It is essential that you run the Redshift plugin compiled against the correct version of Houdini.
Failing to do so will result in Houdini crashing, as the libraries will no longer be compatible.

For example, the following Production Builds of Houdini 18.5 will work with these Redshift versions:

Houdini 18.5.351: From Redshift 3.0.32 to the last available
Houdini 18.5.408: From Redshift 3.0.34 to the last available

Please refer to the Redshift documentation to see which Redshift plugins support which Houdini versions.

To use Redshift with Houdini, you will need to edit your houdini.env file that matches your operating system. This will tell Houdini where to look for the plugin. Please refer to the Redshift documentation on how to configure the plugin for your operating system.

If you are having issues with Redshift, please contact Maxon support.
