Step 6: Render Output - Illumination (Direct)
There is an important Render Output found under Add Layer > Render Outputs > Lighting > Illumination (Direct). It generates a channel exclusive to the illumination in a scene from all direct light items, such as the Area lights in this scene, independent of all other illumination types and surfacing attributes. I like to use it with Soft Light blending mode on top of my Final Color Output.
This Direct Illumination Render Output is great for enriching the Final Color Output
Step 7: Render Output - Illumination (Indirect)
This Render Output is found directly under the previous one. Its output generates an image exclusive to the illumination in a scene from all indirect sources, such as image-based lighting and luminous polygons, independent of all other illumination types and surfacing attributes. Next I will show you how I use these Render Outputs in the final Photoshop composition.
It looks like there is some voodoo going on here, but it's just another Render Output from MODO!
Step 8: Post-production - Part 1
We begin the post-production with the Final Color Output. Take it into Photoshop now for some fine-tuning...
Before I evaluate the final result, I always try to take some time away from a project, so as to approach any post work with a clear mind
First of all, I find the cloth fabric has come out a bit too light, so I'm going to darken it here. This is where the Surface ID comes in handy. I select a little piece of the color of the cloth part and then choose Select > Similar. Then I select my base render layer and hit Ctrl/Command and the J shortcut key. This creates a new layer on top with a copy of this selection. I give this layer a Soft Light blending mode.
Next, I address the color difference between the face skin and body skin. Again, I use the Surface ID render output to select the body skin part and use that as a mask for a Color Balance layer.
I then realize that /My Kiwi Friend/'s lips should be a touch shinier. So I do a quick Region render in MODO of only the lips region with a higher specular amount setting, and lay that on top in Photoshop.
The Surface ID output is great for isolating areas and then creating masks
Step 9: Post-production - Part 1
Next I use my other Render Outputs to take this image to the next level. First, the Ambient Occlusion is applied at 33%, set to Multiply. Then I mask out the parts of the face that I find a bit too dark.
I then apply the AO again, but only where the cloth meets the skin, which is also done with a mask. Next the two illumination outputs (direct and indirect) are applied at 22% with a Soft Light blending mode. This technique gives the image an attractive richness when it comes to the lighting.
I just love this part… everything comes together
Step 10: Post-production - Part 1
I apply a subtle depth-of-field (DOF) effect by using my Depth render output with the Lens Blur filter. I then jump to Magic Bullet Looks to apply a subtle Chromatic Aberration effect.
Finally, I like to add a Max Diffusion filter, which is a combination of Contrast/Saturation/Curves/Diffusion effects. This output from Magic Bullet Looks
is quite extreme, so I apply it at only 10% with the Soft Light blending mode, but it does give a beautiful warmth to the final image.
Magic Bullet Looks has a great set of Presets, but you're free to create your own Looks from scratch with a wide range of controls!
Subtlety is key in post work. A layer opacity of 10% might seem low, but here it does the trick
Top Tip: HDR Light Studio - Revolutionize your lighting
Using HDR Light Studio
, you can light your shots by placing light and reflections directly onto the 3D view – with a dynamic HDRI map generated on the fly. This revolutionary lighting technique allows 3D artists to light their shots faster, and produces stunning final renders.
