Game not launching.

[ErhanK]

I started a project and built it as both debug and release. Either way, the game hangs on a black screen at the start map.

Windows 11 Pro 64-bit (10.0, Build 22631)

13th Gen Intel(R) Core(TM) i7-13700H (20 CPUs), ~2.4GHz

NVIDIA GeForce RTX 4060 Laptop GPU
32GB RAM

What version does the editor show in the titlebar?

Version 0.9.5(Steam) - Build 655

I am looking into it. In the meantime, version 0.9.4 is available to choose from in the application settings in Steam.

Hi, I just tried the following with a GEForce 1080 and the latest driver 552.12.

• Deleted the file "C:\ProgramData\Ultra Engine\settings.json" to reset all settings.
• Launched Ultra Engine Pro on Steam, default branch (0.9.5)
• Created a new project.
• Opened the Visual Studio solution and compiled for debug and release.
• Ran the game, and the start.map game opened and ran.

Questions:

• Are you launching from the editor or from Visual Studio?
• If you are in the editor, do you have the start.map scene open in the editor when you launch?
• This is a new project, right, not an old project that was previously created with the Vulkan build of Ultra?

It sounds like maybe the program is not loading the starting map, so there is no camera and just a black screen.

Hi, I will try again.. After building, I started it from the editor and start.map was open. This is my new computer. I freshly installed the 0.9.5 version and created a project for the first time. It was not a project I had worked on before. However, when I created a fresh project, the project manager informed me to upgrade the project.

By the way, the program does not seem to render the black color. When I run the game, the program stops responding. No matter how long I wait, it stays that way.

[Josh]

Perhaps a dumb question, but have you been here?: https://www.nvidia.com/download/index.aspx?lang=en-us

I wouldn't miss something like this, trust me. I will try again and try to provide you with more detailed information.

Was this only occurring when the game is launched from the editor? We had a problem where the process was being blocked because its output pipe was not being read by the editor after launching, which would cause the game to freeze on a print command. This was recently fixed.

Does this happen when running the game from Visual Studio, or only when launching from in the editor?

The user reported that the console is continuously printing "Invalid operation" errors while the game runs.

Hello, I have same problem with engine.
I have the similar setup but instead 13700h I have 12700h.

Here the problem is in graphics from Intel. If you disable igpu and switch to dgpu, the problem will not arise.

Some addtional info about the problem. 
The problem appeared after version 0.9.4 when using Intel graphics. Updating igpu drivers from intel does not solve this problem. 

The editor does not start on new version of the driver. On old version (automatically installed by windows), it can launch but viewport does not work (just a gray image).
If I compile through Visual Studio I get a black screen and error messages (I attached the screenshot with messages below).

[Josh]

Hmmm, perhaps the OP's problem is that Intel graphics are being used instead of the Nvidia card.

You can check by adding this code to your main loop:

        while (PeekEvent())
        {
            auto e = WaitEvent();
            if (e.id == EVENT_STARTRENDERER)
            {
                Print(e.text);
            }
        }

Now it's working
