Filter Forge Ice Giants
Posted: 18.04.2021, 19:13
So here's something I wanted to show off. A few of you may remember that I made an ice giant for CelWP named "Darler." I had made a custom filter a while ago in a program called "Filter Forge" that I can use to make realistic-looking ice giant textures, which is what I used to make Darler. Here's another generated ice giant texture made using this preset:
Here is an ice giant in Celestia with its textures in use:
(Rings made using a separate filter that I might talk about another time)
Added after 18 minutes 14 seconds:
There are 9 settings for this filter, 7 of which determine the overall look of the textures (6 of those for the surface, and 1 for the clouds), while the other 2 just swap between the surface texture and the cloud texture (with or without alpha).
Added after 33 minutes 54 seconds:
-The temperature parameter goes from 0 to 100, and changes the color of the ice giant's surface texture depending on the temperature. The color goes from a Neptunian-blue at value 0 to a lemon-yellow at value 100, with a Uranus-like (but kinda not really) green somewhere in the middle (value 50):
-The band distinction parameter goes from 1 to 100, and this changes the visibility of the darker bands on the surface texture. At value 0, the bands aren't visible (perfect for Uranus-like ice giants), while at value 100, they are clearly visible:
-The band variation parameter basically just changes the variation of the bands on the surface (value goes from 1 to 30000).
-The band distortion parameters (Cloud Dist. Var. 1 & 2) simply just determine the distort variation of the bands (values on both again, go from 1 to 30000).
-Surface variation just changes the seed for the main surface (value yet again, goes from 1 to 30000).
If we check the box that says "Cloud Map," we will be given the planet's alpha cloud map texture, which is nothing more than just white cloud streaks on a black background (unless of the "Clouds with Alpha" box is checked which will display the cloud map for use in Celestia):
-The cloud variation parameter (Cloud Streak Var.) is the only parameter that affects the cloud texture, and again, it pretty much changes the seed for the clouds (value goes from 1 to 30000).
Overall I'm pleased with how this filter turned out and will use this for more ice giants that I might create sometime in the future.
