Install FP5 and FP6 at same time on different Max versions.
« on: April 05, 2018, 08:51:40 AM »
Is it possible to have Forest Pack 5 and 6 installed at same time on different Max versions ?

Both versions share a common folder and several registry keys. So, it can be done but requires some manual adjustments:

- Install FP5 as usual.
- Be sure Max is closed.
- For each Max version you want to use FP5, rename the Max root folder to any other name (as C:\3dsmax2017 -> C:\3dsmax2017_a)
- Install FP6.
- You will find the setup program has created a new c:\3dsmax2017 folder, with the FP files within it. Just delete it.
- Rename "C:\3dsmax2017_a" to its original name.

This is required because the setup programs uninstalls existing FP versions, before installing a new one. Renaming the Max root folder, we avoid the FP files for that Max version are deleted.

With this process, FP5 will use the common files of FP6 (stored at "C:\Program Files\Itoo Software\Forest Pack Pro"). But that should not be a problem, except for the new libraries.

Also it may be a good idea to make a copy of the FP5 common files, before installing FP6 (at "C:\Program Files (x86)\Itoo Software\Forest Pack Pro").
We have replaced the old "HQ Plants Free" by our own library. So you may need these models or maps for older scenes.

Please note we don't guarantee the backward compatibility. A scene created created with FP6 may not be work with FP5.
For example, Custom Edit objects edited in FP6 cannot be opened in FP5 (they show as empty), because the format is slightly different.

please considere doing a real improvement of this workaround, because this is actually too tricky...

We have about 100 workstations & 200 renderNodes and this manipulation cannot be scripted, so this is a real critical point when you have 2 or 3 different productions with different pipelines/softwares versions.

This might be a source of trouble for you, i know that Ephere Ornatrix or Sitni Sati FumeFX have same kind of problems. They have worked-around by releasing the .exe OR the .dll files so we can deploy it manually with command lines.
This is not the best solution for me (like Vray installers are ), but it actually works.

Thanks a lot !

This procedure was designed for casual users, which usually own a single workstation. But it can be simplified a bit for large installations.

You can do this:

1) Install FP5 in any workstation.
2) Make a copy of all Forest files which are installed in the Max folder. You can find the list here (search for the <maxdir> section).
3) Install FP6 (that will uninstall FP5).
4) Copy to the desired Max version, the files from step 2.

That should result in a functional installation of FP5, but using the assets of FP6.
This is not a big problem, since most of assets are compatible (perhaps with the exception of the new libraries included in FP6).
In case you miss some library (i.e. HQ Plants free which was removed in FP6), you can make a copy from "C:\Program Files (x86)\Itoo Software\Forest Pack Pro" before of step 3.

As you can see, the key are the files stored in the Max folder, which can be deployed by a script once you have them.

I hope that helps.
