Some of the render nodes are working fine, but some are not!
This usually means there is some difference between the render nodes. For example:
- Different versions of 3ds Max installed on different computers (e.g. SP1 and SP2 or 2020.2 and 2020.3)
- Different versions of Corona installed (e.g. version 8 and 9)
- Different versions of 3rd party plugins
Installing exactly the same software versions and updates usually helps in such cases.
It is also possible that some files are blocking 3ds Max from running (for example old plugins) - in such case an error message pops up when 3ds Max is started and this makes it impossible to use DR. You can check for this issue by manually starting 3ds Max on the nodes. If that's the case, it is advised to remove the offending plugin files.
Please also make sure that your system date and time is set up correctly on all of your computers!
