Change the IP address on Fusion 16 Render Node

Hi,

Is it possible to change the ip address of a Fusion 16 render node?

The software is automatically prioritising a network adapter that is not part of the network with the master licenced machine.

The master machine can see the node via the desired ip in the render manager, but the render node itself not to register the licence from the master, as it is set to 10.0.0.7

When I disable the 10.0.0.7 network adapter, the software finds the correct one and it works. Unfortunately I cannot disable this adapter.

Is there a pref file I can modifiy to force the correct ip?

Many thanks

There's an environment variable, FUSION_LICENSE_SERVER which can be set to the IP of the license server.

On macOS, I might try executing the Render Node from the command line with:

Code: Select all

FUSION_LICENSE_SERVER=192.168.0.10 /Applications/Blackmagic\ Fusion\ 16\ Render\ Node/Fusion\ Render\ Node.app/Contents/MacOS/Fusion\ Render\ Node

On Windows, open Settings, search for "Environment Variables", and you'll get this UI:


Choose Environment Variables in the bottom right, then you can add the variable in the Environment Variables UI that pops up.

Then restart the Render Node and see if that works.

I believe it's also possible to embed environment variables in config files. In Fusion Studio, one can open the Console and type:

Code: Select all

-- Tell Fusion Studio where to hunt for a multi-user license dongle on the local LAN network:
fu:SetPrefs("Global.EnvironmentVars.FUSION_LICENSE_SERVER", "192.168.1.12;*")
fu:SavePrefs()


Which would save that to the preferences file of the current user. I'm not 100% sure how to transfer that to the Fusion Render Node. But you could try running that in the Console on Fusion Studio, then open your preferences file (it'll be in Profiles\Default most likely, under the Fusion AppData directory), find the text it just added, then copy insert that text in the same place in the preferences file for your Render Node.

But hopefully just setting it in the environment variables for the current user should be OK.

Tom, thank you!

The env variable worked perfectly.

Really appreciate your insight and time on this.

Cheers Tom.

That's great Dan, glad it helped.

I was just writing the following when your reply came in, so I'll post this for future reference, in case anyone needs it in future:

I looked into this in a bit more detail today.

Running the Console commands I listed result in the following being added to Fusion.prefs:

Code: Select all

EnvironmentVars = {
         FUSION_LICENSE_SERVER = "192.168.0.20;*"
      }

This was added near the bottom at the file, in the Comp = { ... } section, which covers nearly the entire file.

The Render Node config file is called RenderNode.prefs, and on Windows it will be found at this location:

Code: Select all

C:\Users\USERNAME\AppData\Roaming\Blackmagic Design\Fusion\Profiles\Default\RenderNode.prefs

It should be possible to add the code listed above to this file. The method I would suggest is:

1. Close Fusion Render Node
2. Make a backup of RenderNode.prefs
3. Open RenderNode.prefs in Notepad, or ideally a code editor's text editor such as Visual Studio Code or Notepad++ (both are free). Don't use WordPad, Word, or any other rich-text editor.
4. Search down for this text (the version number may vary slightly if you're not running 16.2.4)

Code: Select all

   Version = {
      16,
      2,
      4,
      144,
      "8.0"
   },
   Comp = {

5. Then modify it like so:

Code: Select all

   Version = {
      16,
      2,
      4,
      144,
      "8.0"
   },
   Comp = {
      EnvironmentVars = {
         FUSION_LICENSE_SERVER = "192.168.0.20;*"
      },

Of course changing the IP address to the correct one for your license server.

6. Save the modified RenderNode.prefs and run the Fusion Render Node

It should now hopefully find the license server without requiring any environment variables set.

This method is an alternative to setting environment variables. You can use either method, but there's no need to do both.

I think I am having the same issue. I get this IP address in the render node which I think is causing my issues with deadline/render manager

ipissue.png (9.29 KiB) Viewed 872 times

it's a laptop connected via router. it used to work for me rendering through deadline. now it seems that no matter what, the render node is not connecting to the comp sent. if I try in render manager, the master computer recognizes the render node - but fails upon render. I think it's something to do with this IP. I tried the instructions but wasn't sure I am doing this right.

also tried to do it in the rendernode.prefs

but the ip stays the same, and I am stuck with my issue. wrote about it here also:

would appreciate any help

UPDATE - eventually I was able to narrow it down to the fusion node status in the remote computer which stated "no license". turning off the firewall in THE HOST computer for private network fixed it. having fusion allowed in the firewall was not enough
