Hey folks, love using TerrainControl. Going to have months or years of fun with this.
I've been trying to fix something for a few days, and ultimately will resort to a fallback measure and a post because I'm starting to think this may be a bug.

When I am using the FromImage mode, my rivers are coming out as oceans. I am using #0000FF in all rivers, all throughout my image file. Everything else works perfectly.
For now, I have set the ImageFillBiome to River and hope to wait for a fix.

I did experiment with other river settings in other worlds before using the FromImage functionality, but in this world's WorldConfig.ini file I have since changed the river settings back to false (no longer improved or random) just in case the FromImage function was still reading those variables. For now, the only fix I have is the ImageFillBiome.

Are you guys sure you set it to read River for #0000FF? I discovered some out of date codes in the .bc files as well that I am going to post about when I wrap up deployment.

TerrainControl is not hardcoded to interpret #0000FF as river. Instead, it uses whatever the BiomeColor or your river biome is. So make sure you have the BiomeColor of the River biome set to #0000FF. Oh, and also make sure that no other biome uses that color, otherwise TerrainControl will get confused.

Oh, good tip you added, glad I saw that.. maybe it's being used in my BiomeBundle world for another .bc file, yeah! Rutger that possibly would not have occurred to me, thank you. I was going to need the Ocean fill option very soon, glad you see your response. That's definitely it.
