Lumion V3.0 Fog
Lumion 3.0 will feature improved real-time fog. The fog effect has been overhauled with a nice new color-picker as opposed to dialing in your RGB values manually as well as a better falloff curve.
A Brightness slider complements the effect allowing for subtle changes. Fog responds to Sun and Sky settings and will be influenced by pretty much all other effects allowing you to tweak levels, exposure or gamma.
For novice users it can be daunting to configure this effect to realistic looks, all the more since it responds to so many other effects. However, it is worth it to apply it to almost every scene imaginable, certainly outdoors, since it will play a crucial part in selling your realism.
Mostly overlooked but worth mentioning is the fog ability to darken a scene perimeter by tuning the brightness slider almost all the way down and picking a darker hue for a particular color segment. This is a great and easy way of bringing focus to a particular area of your scene.
Fog can be animated via keyframes but is a static effect by itself, ie there is no animated noise incorporated. Fog also lacks real volumetric properties. Light is effected but not in a truly volumetric way. Above certain camera heights, Fog falloff will cap and look flat. Keep this in mind when doing area shots of sorts.
Sample Scene details:
- Landscape mesh -approx. 1mln triangles- created with Terresculptor
- 4K Diffuse Texture created with Terresculptor on twice the resolution of the landscape
- 4K Normalmap created from Diffuse with some additional detailing via Photoshop
- Rendertime per 1080 Full HD frame around 10 seconds on a GTX580
Note: Terresculptor is a beta program comparable to WorldMachine.
It’s a great little tool allowing you to create fairly realistic landscapes with ease.
