Hi,
I've posted my latest terragen-picture 'dusk' today using terragen 0.9.43 and maybe there are some people here wanting to create a similar sky, so I will write down the way you can get it. It's important to try different changes from the parameters to see what they do! I hope you enjoy it. Let's begin:
1. Create a 1025-terrain (1025x960 for the unregistered user), you can use first a flat scene where you put in later some mountains or other stuff (maybe by using View/Sculpt) If you prefer a more realistic terrain, so try following settings: Realism=98, Smoothing=8, Glaciation=79 and Canyonism=12 - method: Subdivide & Displace II) point-spacing=17.8, camera fixed high above surface on 455m. Before searching a POV we'll do the following:
2. Get into the Cloudscape menue. Sky size 15000, Altitude 2500, Depth/Thickness 6, 3D enable (thats very important to get realistic clouds!) Density Contrast 5 and Density Shift 44, Darkening 88%... that'll do!
3. Generate Clouds using Persistence 55 and Cloud Size the third position behind the maximum.
4. Open Atmosphere and try the following values:
simple haze: color(R-G-B) 35-18-8, Density 29%, Half-height 2048 m
atmospheric blue: color 10-18-59, Density 36%, Half-height 6517 m
light decay: color 231-171-121, Decay 45%, Half-height 3327 m
(it is useful to save in between the parameters)
5. Now we open the Lighting Conditions:
First enable all shadows! Sun heading 0 and Sun altitude 8 above ground level. Here you can do a first render after setting your POV a little beside the midpoint so that the sun can explode in front of you... not in the boring center! (set the detail for testrenderings on second or third position, but don't forget to set it high again before doing the final render!)
Direct sunlight tab: Enable 'realistic sunlight penetration system' - the onliest way to get fine results!
sunlight strength: 1500% (yeah, the sun will burn!!)
effect of atmosphere 73%
where cloud casting not... 0%
Base sun color 119-138-168 (we are gettin' reddish)
Sun's appearence tab: o.1 Disc diameter (deg) and corona size=2
thats it for the first! You have to generate differnet times new clouds to get a good result but don't change the parameters too early!!
6. I think that water is necessary, so open the water menue:
Try following adjustments: a) waves/ wave properties: 48-155-200
waves/wave variation: 100-300-20-20 (default)
b) Reflections/Reflections of Lightsources: direct sunlight about 50%, Reflection spread about 1-5, maybe more. This depends of the clouds you have generated!
c) Sub-surface: try the tropic one: setting the diffuse color from black (0-0-0) to blue-green (0-9-15)
...and now: play with it. The final render should be on highest detail and if you have the registred version put it on ultra for the anti-aliasing!
Hope I could help a little bit and you are on the right way to let the sun explode! :FIREdevil
