Infinite series with mirrors...

Hello again,

I just noticed that iRender doesn't seem to know what to do when you are looking at a mirror that points back to a mirror, which looks back to the original mirror. Follow me? Like going into a FunHouse at an amusement park. iRender renders the overlapping section as black.

Is there a setting to address this? eg something to do with reflective bounces? Seem to recall seeing a property like that somewhere.

regards,

-randall

Reflective bounces is on the Render options tab.

It's set to 3 by default.

Try a higher setting.

Thanx Rich, bumping that up from 3 (the default) to 4 sorted that out.

We didn't want to spend time processing reflective bounces which, normally, do dot usually impact the rendering.

For mirrors you can often see 10 or more bounces. But for other partially reflective surfaces, such as wood or a floor, processing for than 3 bounces is usually a waste of processing time.
