ReLight, Multi-pass and Studio Light Pro : Add realism to your preferred models

Author: myvirtuallady

Tools Needed

* DAZ Studio 1.7

* ReLight

* Studio Light Pro

* Fireworks or Photoshop


Add realism to your figure using Studio Light Pro and improve your scene in postwork with ReLight. Take the advantages of Studio Light Pro lightings, multi-pass renders and postworks with ReLight. This tutorial uses DAZ 3D Models like Victoria 4.1, Domino for V4 and Radiant Jaguar Hair for example.


Step 1: Setup your scene to render

Open DAZ Studio and setup your scene first : Display the Viewport Option and select the Background Color…Select the color that will match your background at the postwork step. I choose this color more darker than the background I will apply further: dark blue for a blue background.

Load your figure and clothing, then apply your pose. In this tutorial I loaded Victoria 4.1 with standard resolution texture maps, Domino for V4 outfit, Radiant Jaguar Hair and fit all to Victoria 4.1.


In the Content Tab, open the Studio folder and select your favorite Studio Light PRO preset (normally inside Light subfolder): in this example I selected Pin-up B Low B preset, in the Pin-up subfolder, inside Presets of the Studio Light PRO folder. Now the scene is set up with realistic lighting for Victoria 4.1., ready to render with ReLight.


In the Content Tab, open the Script folder and inside its Utilities subfolder, select ReLight. The ReLight– Multipass Renderer window opens. Choose Specular, Diffuse and Ambient lights, give a generic name to your files and render your scene into the folder you like.


You obtain 3 render images : Ambient, Diffuse and Specular. These pictures are used for postwork.


Step 2: Import and organize your multipass render into Fireworks or Photoshop

Open your preferred 2D Graphic program and import the 3 render images as layer and rename them Ambient, Diffuse and Specular as needed.


Define the Blend Mode of the Diffuse and Specular layers as Screen!


Step 3: Modify the curves for the Diffuse layer

Select Adjust Color Filter in the Filter dropdown menu using the Property inspector, and choose Curves… The Curves window opens. Then drag the Curves to adjust the tonal range of the Diffuse layer and lighten your figure.


Step 4: Duplicate the Specular layer and adjust the levels of highlights

The result is pretty good but the scene lacks of highlights for the skin and some part of the clothing. At this point of postwork, I will play with the Specular layer to add more realism. Add your preferred background and turn off its visibility.

Duplicate the Specular layer and rename it Specular2. Then modify the highlights on both skin and the clothing to reproduce and simulate a little effect of radiosity : To do this, kept only the Specular2 and Ambient layers visible and turn off the visibility of the other layers. Select Adjust Color Filter in the Filter dropdown menu using the Property inspector, and choose Levels. The Levels window opens. Drag the white triangle to the left side to correct the Specular layer and kept a high concentration of highlights.


Like this, you can duplicate several times the Specular layer in order to play with each area independently if you want more highlights for the hair, or less for the clothing. When you duplicate your Specular layer, do not forget to define its Blend Mode as screen!


To match the color of your preferred background, select all the transparent area using the Magic Wand tool with a value of 10 for Tolerance and Anti-Alias for the Edge. Expand your selection marquee with a 1 pixel value to trim the highlights of the Specular2 layer.


Step 5: Final touch

Finally turn on the visibility of the Specular2, Diffuse, Ambient and even Specular layers. Here is the enhanced renders after postwork. Your figure looks like more realistic with highlights on cloth and shine onto the surface of the skin.


Once you have setup your Diffuse, Specular and Specular2 layers and obtained the good results, you can turn on the visibility of your preferred background. Comparison with postwork and without postwork.


Here is the enhanced render after postwork. Your figure looks like more realistic with highlights on cloth and shine onto the surface of the skin.
