Is there a way to have my custom leaves use a different Colormap/Colorizer in the overworld than the standard green one?

Hi

 

Yes.  In BlockLeaves and derived classes, check out:

    @SideOnly(Side.CLIENT)
    public int getBlockColor()
    {
        return ColorizerFoliage.getFoliageColor(0.5D, 1.0D);
    }

    @SideOnly(Side.CLIENT)
    public int getRenderColor(IBlockState state)
    {
        return ColorizerFoliage.getFoliageColorBasic();
    }

    @SideOnly(Side.CLIENT)
    public int colorMultiplier(IBlockAccess worldIn, BlockPos pos, int renderPass)
    {
        return BiomeColorHelper.getFoliageColorAtPos(worldIn, pos);
    }

I have it working but my leaves appear gray in the inventory, how do I fix that?
