Daz 3Delight Render Sparklies

An occassional problem I have encountered when rendering some scenes is what I call 'Sparklies'. They appear as small square groups coloured dots in what appears to be random points on a render.

Whilst not very odten, this issue has cropped up over various machines I have owned and so I'm pretty certain it's not my hardware. Whether it's cause by various combinations of Light Type/Setting in relation to a prop/surface setting I know not but I do know is - it's really annoying.

The image section of the ISS iwas just a quick test with the Blue Planet prop initialy using the Blue Planet light which is a Distant Light preset in Deep Shadow Map mode. Whilst I suspect it may have something to do with being in Deep Shadow Map mode (I just tried it in Raytrace no problem) I may be wrong.

Any Clues?

    I have seen that solution offered many times on the forum here, so I think you are NOT wrong :)

    Switch to raytrace was the solution directly from the developers of 3Delight,it's been a bug in 3Delight for a long time.
    btw you can turn the shadows off on object in 3Delight by selecting the object and turning off "cast shadow" in the objects parameter.

    It's a "shadow map only" bug. But for me, it was solved in DazStudio 4.7

    I'm having this issue again with 3Delight in Daz 4.9. Besides using raytraced shadows (which defeats the purpose of upgrading my graphics card if the speed will be slowed), are there any other options? 

    Sorry for bumping an old(er) thread.

    3Delight isn't going to get any benefit from your graphics card whichever setting you use, and RayTraced shadows is the fix (or, I think, keeping the ttal inensity of all lights to no more than 100%).

    First 3Delight does not use a graphics card for rendering, so that is not why it will slow down.  Second, DeepShadowMaps may be useful for quick, 'test' renders but have not been recommended by the 3Delight team for quite some time...and in the last version and current version (11 and 12) are more than strongly recommended against.  Third, properly configured a raytraced render can be FASTER than a DSM, especially when figuring in the extra map generation time.  Enabling 'Progressive' rendering, in the Render Settings turns on the raytrace 'hider' that is often much faster.

    Though it can require more samples to avoid noise, especially using soft shadows or AO.

    And in 3DL 12, even at high sample rates, it's faster...(and 4.9 does have a build of 12 in it).
