Sorry to hear you're facing these troubles. First let me mention, that the support for V-Ray 3.6 has been added in the Forest Pack Lite/Pro 5.4.0
(you can download the latest installer from User Panel
- My Products
) and you shouldn't be facing any troubles with it as the latest version is fully compatible with 3ds max 2012 - 2018
(32 or 64 bits) and currently supported V-Ray versions are 2.5, 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6.
Let me point out, that when installing our plug-in, please double check you are not running any 3ds max or related (like the VRay Spawner) service during the installation process. Sometimes, even closed, 3ds max might not shut down correctly and its processes are still running in the background. To check this you can go to the Task Manager by pressing Ctrl+Shift+Esc and make sure they've both has shut down correctly.
I would suggest you to try the following:
- Be sure 3ds max and VRaySpawner are closed
- Delete the ForestPackPro.dlo from the "plugins" Max folder (<maxdir>\plugins\ForestPackPro.dlo) and all ForestVRay??.dll files from the max root folder
- Reinstall the Forest Pack plug-in
Hope the re-installation helps and please let us know that's all working fine or you are still facing troubles with it. Thanks in advance for any further comments on this issue you can share about it with us / our user community.
"I have Vray 3.6 and Forest pack 5.4.1 (yes an old one)"
Might be, you're using an older FP version (not the 5.4.1)? That would explain your troubles. As mentioned above, the V-Ray 3.6 is supported currently in FP 5.4.0 & 5.4.1.
