Applying vanilla textures to new blocks.

[Chris Dunaway]

I have created a "Corner Bars" block that can be used with the iron bars (not centered) to create nice corners.

I would like to texture the block so it matches the existing iron bars.  I thought I could just use the existing vanilla texture to do it, but I cannot find how to do that.  

I tried adding 

<property name="Texture" value="446"/>


to the entry in blocks.xml but it had no effect.  My model does have a material.  I have been able to make changes to it and it appears in game.

Is there something that I am missing?

Thanks
