[1.7.2] [Solved] SkyRender and WorldProvider

delpi · May 14, 2014

I've got a custom sky render working but I've got an odd problem. The color of the sky gets lighter if I'm near a light source.

This doesn't seem to happen in a normal dimension. Anybody had this experience?

I want it to be a black sky with starts, but when i get near a torch it becomes closer to blue.

In my dimension, I have it set so that it's dark 24/7.

I'm getting the same effect, the closer I get to a light source, the brighter the sky is.

Then please show your code..

I'll paste it tonight. Not sure it will help though, its something that isn't there, not something that is wrong.

Here is the relevant code.

}

@Override

@SideOnly(Side.CLIENT)

public float getStarBrightness(float par1) {

return 1.0F;

}

@SideOnly(Side.CLIENT)

return 0.90F;

}

@Override

protected void generateLightBrightnessTable() {

float f = 0.0F;

for (int i = 0; i <= 15; ++i) {

this.lightBrightnessTable = 1.35F * (float) Math.pow((1.0f - 0.0895f), 15.0f - i) - 0.35f;

//this.lightBrightnessTable = 1.25F * (float) Math.pow((1.0f - 0.10f), 15.0f - i) - 0.35f;

}

@Override

}

}

@Override

// Return pitch Black

return this.worldObj.getWorldVec3Pool().getVecFromPool(0, 0, 0);
