Cannot launch Nsight Graphics, connection error detected communicating with target application For unreal 5.2

Developer Tools Nsight Graphics
1

I observed abnormal behavior in the material preview, therefore I need to capture a frame to examine the rendering process of the preview material in the editor window. I can launch the editor normally, but when selecting a specific project from the editor, an error occurs. I am able to capture a frame when entering the specific project, but it results in an error. How can this be resolved?

Hi, @swzwork

Which editor do you mean ? Are you using Nsight Compute ? Note this is forum for Nsight Compute tool.

I mean editor for unreal 5.2

Thanks ! Are you using Nsight Graphics or something else ? This is not UI for our Nsight Compute.

Sorry to bother you. I am using GPU Trace Profiler of Nsight Graphics . What Should I do? like post a new thread in the right forums?

That’s fine. I see it’s already under “Nsight Graphics” now.

Hi,

I just change the title from Nsight Compute to Nsight Graphics for making the topic clearer.

swzwork, can you detail your steps? Is your issue repro-able on some public UE4/5 projects that we can use them for reproducing your issue?

It’s weird that you meet such issue since we test UE4/5 samples regularly before release Nsight Graphics. There may be something we don’t know.

Thanks

Yes, I am using public version of Unreal to do this. New users can post one image only. So I only can say what I did.

  1. config connection like previous:

  2. press down Launch button, start UE 5.2 editor, it succeeded.

  3. then I select AnimToTexture2 which is a 5.2 project, it will report an error:" Cannot launch Nsight Graphics, connection error detected communicating with target application"

4.When I open the static mesh asset, It shows that I can do frame capture

  1. But when I press F11, it will show an error, which content is showed in the first image of this thread

6.When I press “确定” which means ‘Yes’ in Chinese, It will show the replay window, I can watch draw process result without any details in this tool.

Hi,

It seems AnimToTexture2 is not a public UE5 sample project (like CitySample), does this issue happen on AnimToTexture2 only? or it’s repro-able on any blank UE5 project file (like the template of UE5: First Person, Third Person, etc.)

Thanks

Happy New Year. I have checked it out that this project is a default project of Third Person, and I tried on a totally new default Third Person project, same error happened again.

Hi,

Yes, I can repro this, an internal case had been created for tracking this.

Hi swzwork,

I think this issue will be solved in the coming release of Nsight Graphics. Please note, you might still see the ‘Replay Window Interference’ about ‘Replay window interference possible due to topmost window settings’, choose ‘Cancel’ button. Another note for using Nsight Graphics on Unreal Editor, please dock the mesh asset window beside the main level window (by default, if you click the static mesh asset, it will show a float window about the current static mesh for mesh model viewer, make sure it’s docked within the main window beside the init view, like multi tabs in one Chrome window)

I can do frame capture on UE5.2 Editor with the internal unreleased Nsight Graphics smoothly, include the Shader Profiler feature (doesn’t meet the ‘Error initializing experiment!’ error in my test environment)

Thanks
An
