Request for SSH forwarding functionality for raisimUnity (remote simulator process & local raisimUnity)

Can you elaborate on your setup? Do you have a remote Linux machine and a local Mac?

I haven't tried it between two different OS's. My students use a remote Linux machine and a local Linux machine and it works well. I'll investigate it on weekend.

and does the same simulation/visualization work well on a local machine?

The above screenshot which shows the error msg is taken on the raisimUnity on my local Mac (git commit 091b625) when it's trying to try to connect to a remote Linux (git commit 5a6592d) where the simulator runs.

local Mac system info:

• macOS 10.15.7
• 8-Core Intel Core i9

remote Linux system info:

• Ubuntu 20.04.1 LTS (Focal Fossa)
• Intel(R) Core(TM) i9-10920X CPU @ 3.50GHz

I also tested a different setting: raisimUnityOpenGL on a local Linux machine (git commit 3357221 Nov 5 2020) and the simulator on a remote Linux machine (same one in the previous setting and git commit 5a6592d). It failed with a resource loading error. Should local resources have the exact same absolute path as the ones on the remote machine?

local Linux system info:

• Ubuntu 18.04.5 LTS (Bionic Beaver)
• Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz

In addition, I tried to update the library on the local linux machine to commit 1d83388 (Jan 15 2021). Same remote linux machine and setting. The error msg of raisimUnityOpenGL changed to:

Can you just update both systems to the latest one? RaiSimUnity is constantly improving and there is no guarantee that two different versions use the same communication protocol.

"Cannot find the meshes.." error is a good sign. This means that you are connected and the two protocols (most likely) match. But you have to have meshes locally to visualize the simulation. On the very bottom, you can add resource directories that contain the mesh files (or its upper directory).

This is how we find the mesh file. https://github.com/raisimTech/raisimUnity/blob/ddc42b8de840c18cd994a7dc64034b161b33e1b9/Assets/Scripts/ResourceLoader.cs#L75

I'll close this issue. I guess I have to keep a better versioning system now in order to avoid such confusion.

I updated raisimLib to the latest version on both my local mac and remote Ubuntu server. RaisimUnity in both machines work perfectly when it pairs with a raisim simulator on the same machine. However, when I do ssh port forwarding of raisim simulator's visualization from remote ubuntu server to my local mac machine, I got this error message. The specs of both machines are listed in the previous posts.

Can you pull and try again? I tested it on my mac machine and a remote linux machine. I am closing this for now
