borisovich Posted May 25 Share Posted May 25 I am newbie. I installed the browser, then copied the demo to the projects, and created a new one. In both cases, a black screen is displayed in the editor viewing area. Poking the mouse at it can see in the side panels that some objects are highlighted, but nothing changes in the viewport. SDK 2.18.1, console without errors. System: Arch Linux, Intel 520 HD, drivers installed. Link to comment
silent Posted May 26 Share Posted May 26 borisovich We officially do not support Mesa GPU drivers on Linux (especially on Intel integrated GPUs) due to it's unstable work. Recommended a PC / Laptop configuration is one with dedicated nVidia / AMD graphics and their proprietary drivers installed. Thanks.

silent Posted July 31 Share Posted July 31 Try to switch from OpenGL to Vulkan API, maybe that would help. How to submit a good bug report --- FTP server for test scenes and user uploads: ftp://files.unigine.com user: upload password: 6xYkd6vLYWjpW6SN Link to comment
parthip Posted July 31 Share Posted July 31 (edited) I tried it by switching from Opengl to Vulkan API. but the editor closes as soon as it opens i got this message in the terminal ---- Render ---- Unigine fatal error: VkExt::init(): Failed to initialize GPU Adapter - GPU Adapter doesn't have additional queue family with transfer Shutdown what should i do?

silent Posted July 31 Share Posted July 31 Looks like Vulkan 1.3 is not supported for your GPU (Intel Xe GPUs are limited to Vulkan 1.2): https://www.intel.com/content/www/us/en/support/articles/000005524/graphics.html I'm afraid, the only option would be to boot into Windows and use DX11 / DX12 API for Editor.

parthip Posted July 31 Share Posted July 31 Thank you silent for your advice. But I am not able to switch to windows or use another gpu currently. So I am planning on using another engine for now and will come back to unigine when I get a new pc This is a very good engine 1 Link to comment
parthip Posted August 27 Share Posted August 27 I would like to use this engine for my current project is there any other way to use it with my current hardware? Does any future updates of the engine makes it possible? i have tried many other engine and find this engine light weight and has better graphical capabilities, so i would like to use this engine for the game i am making.

silent Posted August 27 Share Posted August 27 On Linux, Vulkan 1.3 support is required. If your GPU driver does not provide this support, you will be unable to run the engine. Further engine updates will probably increase the minimal required versions of libraries. Even Proton or Bottles require Vulkan 1.3 to emulate the DX11/DX12 behavior of Windows applications on Linux. Therefore, the only current solution (with your current hardware setup) is to use a genuine Windows installation. Maybe someday there will be support for Vulkan 1.3 for your Thanks! 1 How to submit a good bug report --- FTP server for test scenes and user uploads: ftp://files.unigine.com user: upload password: 6xYkd6vLYWjpW6SN Link to comment
parthip Posted September 1 Share Posted September 1 (edited) Does the engine work if i use windows 11 in a VM? also as you said the vulkan 1.3 is need i checked the vulkan version in my system and the vulkan info file is attached for you reference. vulkaninfo cmd shows that my vulkan version is 1.3 And does the older version of the engine work? vulkaninfo.txt Edited September 1 by parthip Link to comment
silent Posted September 2 Share Posted September 2 Thanks for the provided vulkaninfo. Now we can see that you can't use engine in combination with your current GPU and Linux. Engine is using multiple threads to submit data from CPU to GPU on Vulkan (for async transfers) and your driver is not letting us to do so. If you will try to find VkQueueFamilyProperties in the log you can see that queueCount is always = 1. However, the minimal number that will allow engine to work is 2. For most modern GPUs that number is always greater than 1, so there might be some issues with that particular hardware (or driver) that is not allowing to use async transfers. Maybe in the future driver will support more that 1 queue, who knows. I'm not sure if using Wine with Proton or any similar software will make things work, never tried it. Even if it make engine to start the overall performance on such GPU would be quite low and you probably would not able to work inside the Editor with comfort. Thanks!

parthip Posted September 2 Share Posted September 2 Thanks for the reply. I tried a older version (2.15) and it works properly other than c sharp due to dotnet 5.0 not supported in Ubuntu 22. I have been scripting using cpp and there has been no problem. Thank you for help with my query ☺️ 1 Link to comment
