Custom dimension sky brightness changes with render distance.

[weckar]

I've been working on my own dimension with custom sky rendering, and I have come across an odd bug where increasing the render distance will make the sky (much) brighter, while lowering it makes it much darker. I would not even know what to look for causing this, but I am happy to take any pointers...

Well as a starting point, I'd make sure you're not testing with any other mods involved (if possible), especially any shaders, optifine, or anything else that is likely to do anything graphics-related.

That aside, the only things I can think of are the skybox color/texture, the sun/moon textures, and the fog color.  I haven't messed with any of these and don't know where they're being handled.  There might also be other factors I'm not aware of.

Hmmm I have not been playing with render distance but as far as I know you should play with sky color and fog color cause it seems they're affecting each other. Hope it will point you onto right way.

Yep, after doing a short experiment with render distance in the nether, I noticed the observed "sky color" is far darker at *short* view distances.  Really short view distances are dominated by the fog color, so the nether has a dark fog color, and when you increase the view distance, the fog color has less effect, so in the nether, the "sky" becomes brighter with longer view distances (up to a point)

 

In your case it may well be the opposite.  Ie. your fog color is probably brighter than your skybox color, and your fog color is probably the color you're trying to achieve, I'm guessing.  You may want to try setting the skybox color brighter.

 

Edit: You know what, I might have the skybox color and fog color backwards...in any case, try messing with both and observe the results

Yeah, you're right. Turns out I was fighting the fog color the whole time with odd sky color values. Setting them to the same color vector circumvents the whole issue. Thanks!
