Common errors and solutions for Blender users with iRender

Blender is a free and open-source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, and even video editing and game creation. In this article, iRender will guide you to deal with some problems encountered when using Blender software. Let’s find solutions for Blender now!

Blender's interface is weird or glitchy


  • Blender runs very slowly, may see weird screen glitches around the mouse pointer or menus. 


  • Drivers card may not effectively implement the little-used library features that Blender needs.


  • Check and Update the latest NVIDIA Studio Driver version

Can’t render or render at a low speed on Blender

Some cases are:

  • Blender software does not utilize full GPU performance
  • Blender only uses CPU instead of GPU while render setting is GPU
  • There is a crash while using Blender.


  • Blender software may not be configured to use the GPU for rendering.
  • The GPUs on the remote server may be disabled.

Solution 1:

Open Blender » choose Edit » select Preferences. On the Blender Preferences, select System » select CUDA » uncheck CPU.

Note: If you configure the render engine with Eevee, Blender software cannot use multi GPUs. You should switch to a single GPU package

Solution 2: 

  • Update the latest NVIDIA Studio Driver version

EEVEE freezes when rendering out animation

Blender software can render around 50-400 frames and then it stops rendering new frames. CPU usage goes straight up to 100% when that happens and GPU usage drops down to 0%. The Blender UI is still responsive, it is just that the render seems to get stuck on a frame. If you cancel the render, then Blender becomes totally unresponsive and you have to force quit via the Task Manager.

Blender 2.91, 2.92. 2.93 Alpha all have the same issue.


Go back to 2.83 LTS to render.

Note: This version does not have all functionality of the newer versions.
