Okay, so I am picking up a discussion started in the Show Us Your Bryce Renders thread regarding some lighting ideals. I explained to Mark aka LordHardDriven that the Atrium scenario is a good candidate for the 3D Fill Light. To play along, here is a link to the Atrium Model found here at Daz3d. For Platinum Club members it costs only $1.99.
Here are a few examples of renders of this space lit primarily with the 3D Fill combined with a bit of IBL for skylight. Default Sun provides the sunlight.
Example 1 is pretty large, the other examples are smaller but should help to give an idea of the way the 3D
Fill Lights are operating.
This tutorial will recreate the scene file I used so that you can get these same results at home. Once you have set up the scene we will import the model into Bryce 7.1 Pro via the Daz Studio Bridge. But first we must create the set up in Bryce. As Follows:
To recreate these light conditions you must do the following:
1. Create a New Bryce 7.1 Pro scene.
2. Delete the Ground Plane.
3. In the Sky Lab, load in your favorite daytime sky. If your chosen sky is not already based on an hdri then we must create an hdri based on your chosen sky.
A. Increase Shadow Intensity to maximum 100%
B. For now, make the Sun Invisible so that it wont pollute your HDRI.
4. In the IBL Lab, enable Use HDRI Image . Then enable Use Sky. Bryce will then convert the sky into an hdri. Also enable Cast Shadows. Then you should enable these exact settings.
A. Quality = 32
B. Saturation = 75
C. Intensity = 5
D. Specularity = 0
E. HDRI Effect = 75
F. Shadows = 75
Return to the Sky Lab
5. Converting the Sky to HDRI has automatically disabled the Default Sun, so you must re-enable it. Make sure the Default Sun is at least Diffuse Intensity 75. at an Altitude no less than 65. Ensure that the Sky Dome Color swatch at the bottom left of the Sun&Moon; screen is fully Black in color!!!
6. Again ensure that the Sun Shadow Intensity is at maximum 100%. Enable Soft shadows and limit the range to just 33.
7. Turn off all Haze, an interior like this one doesnt need Haze. Exit the Sky Lab.
8. By now you should be looking at a scene with no ground plane, but with a rather nice sky that is radiating HDR Light. So far so good
9. Now create a Cube 3D Fill Light. Duplicate this light and rotate the second one by 180 degrees along the Y axis. Now select both Fill Lights and edit them at once by applying these exact settings to the Attributes:
A. Position: X = 0 Y = 224.709 Z = 0
B. Scale: X= 722.93 Y= 435.825 Z= 722.93
10. While both of the identical Fill Lights are still selected, Press the Letter “E” and enter the Light Lab. Apply these exact settings tot he Fill lights.
A. Select Gradient instead of Uniform Color. Select Edit to edit the Gradient.
B. You will observe that there is a slider with White on the left and Black on the Right. Switch the colors so that Black ends up on the left and White ends up on the right. Exit the Gradient Editor.
11. While still in the Light Lab apply these settings to your 3D Fills
A. Diffuse Intensity = 170
B. Quality = 64
C. Bias = -30
D. Randomness = 37
E. Distribution = 100
F. Enable Cast Shadows. Reduce Shadow Intensity to 75%
DO NOT ENABLE SOFT SHADOWS!!!!!!!!!!!!!!!!!!
Exit the Light Lab.
12. Now your scene is set up. Now you will start DS from within Bryce by pressing the Daz icon.
13. Once in Daz Studio, locate and load the Atrium Model.
14. Once the Atrium Model has been loaded into Daz Studio, select Send to Bryce (located under “File.”) Bryce will then send the Atrium over to Bryce 7.1
15. At this point you should find that the Atrium models is ready to render. Have fun and please do report back with your questions and observations.
