Just testing DAZ Studio 3’s Volumetric Lighting, don’t mind me. If nothing else, it’s a good excuse to post a render of a gorgeous elven ranger who is armed to the teeth. Go on. Count those swords. I’ll wait.
Using the Volumetric Lighting is easy –
- Add a spotlight (Create->New Spotlight). In thise case I’ve set it to Y=300 and pointing directly down (X Rotate = -90)
- Make sure it’s selected in the Scene tab then head into DAZ Built-in Content->Shaders->Uber->UberVolume
- Double-click Parent Cone to Light
- In the Scene tab, expand the Spotlight and select Spotlight 1 Volume then, in your Surfaces tab (you do have it open, don’t you?) make sure that Spotlight 1 Volume is also selected. As with any Shader effect, you need to have both the object and it’s material selected, remember
- Back in the Content tab, double-click Cloud, Dust or Smoke and fine-tune the effect in your Surfaces tab to taste
- Finally, expand the Volume to cover the entire scene (or as much as you need) in the Paramaters tab by adjusting Z Scale. For this scene I set it to 300% so that the smoke effect went all the way down to the floor
That might sound complex, but it’s not – it’s just harder to explain that it is to do. Try it and see.
There’s lots of potential to Volumetric Lighting – from fog effects to light spilling out of dusty warehouse windows, from adding a subtle depth to a romantinc render to over-the-top rock-god ground smoke MTV video. And much, much more.
Yeah. Tis good. Expect to see more!
