Why did this happen?

okay so I’m an old DAZ artist who went into semi-retirement due to hardware issues and has now returned to the community after 4 years.  That’s a long time in the land of technology and certainly a lot has changed here in the DAZ|Studio community in my absence.  so I’ve been rebuilding my library, reactivating old accounts and redownloading models and utilities I paid for once upon a time. 

I’ve reaccquainted myself with the studio without any real difficulties, except for this one bump in the road.  See, sometimes when I render something I get these odd little red or green squares scattered about the image.  If I re-render, they won’t be there a second time (or they appear in a different place sometimes).  What are they and how do I avoid this problem?  I’ve attached an example so you can see my problem for yourself! smile

Thanks in advance!

Are you using Deep Shadow Maps on your lights?

Just because something costs a lot, doesn’t mean it’s the best…

It just means it’s expensive.

This is a problem with Deep Shadow Maps.  Sometimes changing the camera position slightly will fix it.  It doesn’t happen with Raytraced shadows.

yes, is that what causes it?  I’ve never noticed a difference between the deep shadow maps and the raytraced - can you explain what it is to me?

Raytracing makes more accurate shadows, but takes longer.  Deep Shadow Maps is a way of “estimating” the shadows more quickly.  However, there is a bug in 3Delight which sometimes causes these fireflies to appear when using DSM.
