Still have some trouble to get nice smooth shadow. I used something like 5/6 spotlights but still getting hard shadow. View attachment 160068
Did you try turning it off then on again? Kidding. My only suggestion is lower the intensity of the lights. If you have done that then lessen the amout of spotlights and try linear lights mixed in as well

Have you played with the shape of the spot light? This was a problem we had in the early days and once we learned to alter the shape, that solved the problem.

For example, if you want a nice even shadow, make it a square, and increase the dimensions to 50 x 50 or 100 x 100 depending on the size of the scene. Then play with the photometrics (lumens and temperature) and angle to fine tune.

Ah ah ! Ok thank you for the tip, I will try to lower the intensity.

Wow, thank you ! I didn't think that the light was hard like this to master.

Thank you guys !

You can resolve this by using emmissive lights rather than spotlights. You can see my earlier post as linked below to see method / results.


Edit - Further Notes:
The light emitted from spotlights has a single origin hence will make hard shadows. Emmissive surfaces however project light in every direction from every point on their surface. If you want a reasonably harsh shadow use a smaller emmission surface with higher intensity. If you want a softer shadow, use a larger surface with a lower intensity.

Our experience was that in Daz, light is the hardest thing to master. To help us we studied books on photography light and television lighting (relevant because TV is still a 2D medium and the tricks apply here).

80% of the realism in a scene will come from lighting. It will add contours, define textures, and provide all the visual cues the eyes needs to process the image. It's powerful stuff.

At the very least, learn a bit about a three light rig (Key, Fill, Backlight). You can do a lot just by mixing up these three lights with different angles and intensities. Totally worth the time!

Best of luck mate. Cheers!

I don't personally like to use emmissives for my primary lighting, but they are invaluable when you have a scene with lots of reflective surfaces and don't want the light sources to appear in every reflection.

You can remove the light sources from appearing in reflections by adjusting the cutout opacity to almost zero.
