Change skyland void color?

[bwrobinson13]

Hey i have created a sky dimension similar to the aether and it works great except that the void or "sky" under the floating islands is black.  I am trying to figure out how to make the same color as the actual sky.  Any help is much appreciated! Thanks

I'm in 1.8 and I really need a method for change the void color, if somebody have a solution that can be really nice.

[EmotionFox]

Hello back, I've use this event for change the void color (in white) on my sky dimension :

 

@SubscribeEvent

public void viewRenderEvent(EntityViewRenderEvent.FogColors event)

{

    event.red = (float)((double)event.red * 10);

    event.green = (float)((double)event.green * 10);

    event.blue = (float)((double)event.blue * 10);

}

 

but only the fog color change Did you have any solution for affect the void ?

[EmotionFox]

Sorry to disturb you again but I'm confused, I have override the function but I don't really know what return If null is correct that change nothing

 

@Override
@SideOnly(Side.CLIENT)
public net.minecraftforge.client.IRenderHandler getSkyRenderer()
{
     return null;
}

I've try so mutch but no way to find. Have you any exemple?

[EmotionFox]

Np, thank you at all!

[Abastro]

Do you still need some example? Maybe I have one.

[EmotionFox]

Still need yes and if you have one it would be really sweet

[Abastro]

First; You should provide your version.

Since rendering system of 1.7 and 1.8 is pretty different, it is needed.

[EmotionFox]

I use forge for 1.8 Minecraft version

[Abastro]

It is divided to 4 parts.

I'll first post the default sky rendering code, try to understand how they works.

Ok first, sorry for the late reply but I have take the time for read and it is pretty explicit for the moment so you can go forward I think

[Abastro]

So I think you should change renderSkyOverlay section.

I think this gonne work can you show me how can I try?

[Abastro]

You might change color. I think you should change 'worldrenderer.setColorRGBA_I(0, 255);'

[EmotionFox]

Hum maybe yeah, I suppose you know what you say. Done.

[EmotionFox]

Ok so I've search by myself and I find all I wanted to do, so thanks to you guys it's perfect like this
