Hi everyone, i have been rendering various fractal projects in unreal engine 5.3.
Been working without problems rendering my png files on a external drive , ( a bit slower then disc C but ok) suddenly today after rendering 200 images on 14000 the computer froze, i had to restart rhe render from where it stopped, then again 15 min later it happend , like that 3 times . I could not understand why. Then i see my internet has been on and off and i get a sms from internet company that they are doing work in my area. So i’ m deducting its due to that. Can anyone confirm that why my render stops and frezze my computer ? Or should i check something else ?
Hello there @minddistortion1!
Do not worry, rendering does not use an online connection for the task, so issues on the network won’t affect it. It is, however, a very taxing process in most systems. The most common cause for freezes here is running out of VRAM, specially if you are rendering 14000 samples.
Let’s try some methods to ensure the next render works as intended:
-
Please update your OS to the latest version, and your nVIDIA drivers, make sure you are picking the “Clean Installation” option, as well as going for the “Developer” drivers, as these have more stable settings for engine work.
-
To rule out hardware issues, in Unreal Engine, adjust your values for engine scalabillty, to ensure your equipment is not being exerted.
-
Test disabling Hardware Raytracing from the engine
-
Please make sure that no RTSS or overlocking are enabled for your video card while working on the engine.
-
Reduce texture quality on your images
-
Remove any unoptimized geometry in your scene
-
Use the Level Viewport Screen Percentage to render at a lower resolution
