enter image description hereenter image description hereI set my render to sample 800 samples.

When I look in the corner while rendering it only says 510 and has LOTS of pixelation.

I've never had this problem before.

    $\begingroup$ !!! You have square samples enabled, so you are trying to render 640,000 samples! (640,000 = 800^2) You probably want to disable square samples in Render Settings > Sampling. $\endgroup$

You appear to have a per-renderlayer sample override limit set in Properties > Render layers > Layer:

enter image description here

To avoid this, either set the sample override to 0 in the appropriate renderlayers, or tell blender to ignore per-renderlayer sample overrides in Properties > Render settings > Sampling:

enter image description here


Note that you have Square Samples enabled. This means that blender will use the number of samples you specified2. The total number of samples is displayed below:

(TBH I don't really see the point of this feature..)

Also 500 bounces are almost never needed. Higher numbers of bounces give diminishing returns, and I doubt there will be much visual difference between 6 bounces and 100 bounces in a fairly diffuse scene such as yours.

  • $\begingroup$ From your view, so for all the integrator (however you spell it) settings should be somewhere between 6 and 100? Like the transparency, etc? $\endgroup$ Dec 20, 2014 at 12:22
  • $\begingroup$ I GOT IT! You're a natural! Thank you so much! What I think messed it up is first I made one layer with the car and a second with the land, and probably accidentally changed the settings as I moved all to one layer. Thank you! $\endgroup$ Dec 20, 2014 at 12:25
  • $\begingroup$ Okay, I started another project. It's not working again. I ignored layer samples, set scene to 1000, how do I fix this thing again? $\endgroup$ Dec 20, 2014 at 15:54
  • $\begingroup$ @NoviceInDisguise What is supposed to be different? $\endgroup$

  • $\begingroup$ @BinaryGreen Huh.. Is it possible you could upload your .blend? It sounds like something weird is happening, and this would be the easiest way to find out what. $\endgroup$
