I work on a project were we have very large textures and models by design in otherwise very simple scenes. If we enable these HQ textures and models by default from the beginning, the load times are high and when using normal methods the main thread and UI are blocked during the download of these l…

Downloading is already async being an IO operation. You do not need to do it on a separate worker, but it is still great to have lower Q first to prevent extra long load time.

What would be the correct way to load a HQ texture during runtime without freezing UI or animations then? I tried a couple of things from the tutorial and all of them seemed to completely pause the execution of anything else.

Hello and welcome! Some thoughts and remarks. [image] Leolele99: we have very large textures and models Could you be more specific in order to know what the ‘large’ is in this case? Anyway, there are some limitations for the texture size which is possible to use for a current device. You …

[image] labris: Could you be more specific in order to know what the ‘large’ is in this case? I checked back with my colleagues and as we want to display singular HQ models for CG and product showcases, they would like to use models of up 50mb in size with textures of around 8mb (they would b…

Please be aware that for the real time rendering you may need some model optimization. [image] Leolele99: models of up 50mb in size with textures of around 8mb Do you have more info on your model (you can upload it into Sandbox and open the Inspector to see statistics) - how much it has mesh…

Thank you very much. I will discuss this with our art department and see that we can get them optimised for realtime.

Hi @Leolele99 ! We’ve recently merged a PR that should improve load times on 5.0 Added option to force sRGB Buffer support state by RaananW · Pull Request #11758 · BabylonJS/Babylon.js (github.com) , can you update your project to see if it helps? :smiley:
