I've coded an multi-textured-block in 1.7.2 , but it doesn't work . Here is the code:

package DETheLegendOfGaming.RedPow0rReloaded;

 

import cpw.mods.fml.relauncher.Side;

import cpw.mods.fml.relauncher.SideOnly;

import net.minecraft.block.Block;

import net.minecraft.block.BlockLog;

import net.minecraft.block.BlockRotatedPillar;

import net.minecraft.block.material.Material;

import net.minecraft.client.renderer.texture.IIconRegister;

import net.minecraft.util.IIcon;

import net.minecraft.world.IBlockAccess;

 

public class blockRubberWood extends BlockRotatedPillar {

@SideOnly(Side.CLIENT)

    protected IIcon[] blockRubberWood_top;

    @SideOnly(Side.CLIENT)

    protected IIcon[] blockRubberWood_side;

    private static final String __OBFID = "CL_00000266";

   

    public blockRubberWood(Material p_i45394_1_) {

super(p_i45394_1_);

// TODO Auto-generated constructor stub

this.setCreativeTab(DETheLegendOfGaming.RedPow0rReloaded.RedPow0rReloadedMain.tabProjectRedAddon);

this.setHardness(2.0F);

        this.setStepSound(soundTypeWood);

        this.setBlockTextureName(DETheLegendOfGaming.RedPow0rReloaded.RedPow0rReloadedMain.MODID + ":" + "IIconRubberWood_up");

}

   

    @SideOnly(Side.CLIENT)

    public static IIcon topIcon;

    @SideOnly(Side.CLIENT)

    public static IIcon bottomIcon;

    @SideOnly(Side.CLIENT)

    public static IIcon sideIcon;

   

public int getRenderType()

    {

        return 31;

    }

 

@SideOnly(Side.CLIENT)

public void registerIcons(IIconRegister icon) {

topIcon = icon.registerIcon(DETheLegendOfGaming.RedPow0rReloaded.RedPow0rReloadedMain.MODID + ":" + "IIconRubberWood" + "_up");

bottomIcon = icon.registerIcon(DETheLegendOfGaming.RedPow0rReloaded.RedPow0rReloadedMain.MODID + ":" + "IIconRubberWood" + "_up");

sideIcon = icon.registerIcon(DETheLegendOfGaming.RedPow0rReloaded.RedPow0rReloadedMain.MODID + ":" + "IIconRubberWood" + "_side");

 

}

 

 

public static void init() {

 

}

 

 

 

 

 

    @Override

    public boolean canSustainLeaves(IBlockAccess world, int x, int y, int z)

    {

        return true;

    }

 

    @Override

    public boolean isWood(IBlockAccess world, int x, int y, int z)

    {

        return true;

    }

 

@Override

public IIcon getSideIcon(int var1) {

// TODO Auto-generated method stub

return sideIcon;

 

}

public IIcon getTopIcon(int var1) {

// TODO Auto-generated method stub

return topIcon;

 

}

public IIcon getBottomIcon(int var1) {

// TODO Auto-generated method stub

return bottomIcon;

 

}

 

 

 

 

}

 

registerBlockIcons

 

And if you put the Override annotation over all methods you ever override from Minecraft, you would've figured that out.
