    Unity VR build issue 6 days left
    VERIFIED

    Hey, I'm currently streaming a Unity PC VR game on the Oculus Quest 2 using a Link cable. I've incorporated an interior space model into the game, but I'm encountering an issue. When I set the render scale to 2 and enable 2x antialiasing in single pass mode, I experience significant lag. However, when I reduce the render scale to 1.8 and keep the antialiasing at 2x, I begin to notice distortion/melting effect—this wavy effect when I move within the space, which is a bit annoying. I could really use some assistance with this issue, especially considering that I'm using the single-pass rendering mode. Any advice or suggestions would be greatly appreciated!

    I've developed a web application using .NET Core MVC, which specializes in converting HTML web pages into PDF documents. Users simply provide the URL of the desired page as a parameter. Once the conversion process is complete, the PDF is automatically downloaded to the user's system. For this functionality, I've leveraged a NuGet package known as "DinkToPdf." Additionally, I've installed the supplementary tools "wkhtmltopdf" and "wkhtmltox" to aid in the conversion. While the application performs seamlessly on Windows, I've encountered issues when attempting to deploy it as a Docker image and subsequently running it as a container.
