Can someone help me determine why my render is coming out in such low quality? I have Cycles up to 500 Render Samples, but I have no idea why it looks like it's only using one.

  • $\begingroup$ Here's the next piece of information we need in order to help answer your question: Render it with only one sample. Then render it with 100 samples, and post all three results (including the one you have now) here. $\endgroup$

1 Answer 1


If you have any number other than 0 on the render layers, then your rendering will be limited to that value.

enter image description here.

Solutions (choose one):

  1. Make the number of samples on the render layer, the number of samples you need.

  2. Turn that number back to 0 so that the sampling is controlled by the overall render settings for the scene.

  3. Turn the layer sampling settings to "ignore"

    enter image description here
