Questions about Forest Product [Solved]

dawnblade

Recently purchased Forest by Andrey Pestryakov. The first 3Delight render using the latest version of Daz Studio is the SR preload, through camera 7, DS Light 1 set that comes with the product. There are strange artifacts in the scene that I can't find in the Scene tab. They don't look like flowers, and flowers aren't among the props.

The second render is the same scene through the same camera 7, using DS Light 3 set. No artifacts.

Also, no matter which light set I use, they always consist of 2 spotlights named Light 2 and Light 3, and 24 distant lights named Ambient1-Ambient24. Is this by design? None of the lights have colors matching the artifact colors.

Also got a bunch of severity zero messages like this, if it helps: "3Delight message #43 (Severity 0): R2093: object 'shapematerial_matBranch1_1307_4db' (displacement 'DAZ/Uber/displacement/omDispStandard', surface 'DAZ/Uber/surface/omShadowSurface') used only 12% of its displacement bound"

Any ideas? Thanks in advance for your help!

Those sort of artifacts are usually caused by using Deep shadow maps rather than Ray traced shadows.

I'll check it tonight! I used the default settings that loaded with the presets. Thank you @scorpio!

Yes, unless it's changed the defaults use mapped shadows - which on an object that size don't really work, the whole effect is blurry. Switching to ray-traced shadows actually allows light to come through the gaps in the leaves, as well as eliminating any of the colour artefacts.

That was it! There was one spotlight with shadow type set to deep shadow map. Changing it to raytraced fixed the problem and produced a much better render.

Thank you!
