My system freezes when I start rendering!

This is probably caused by running out of memory. This could happen because of many reasons, and some of them include:

  • Using displacement with high quality settings in a high-resolution image

  • Rendering large amounts of objects or detailed mesh ("heavy" scene)

  • Using many render elements (especially LightMix) within a high-resolution rendering

I am getting a sudden rise in RAM usage!

If the problem is caused by something else (for example it disappears after deleting some object or material), please report it through our Support Portal.
