I have created a texture brush (not a cycles one) and then transformed it in various ways by going into the texture node editor and using nodes. My node tree consists of a cloud texture from the textures node menu, then several mixes and changes, and then ends with an output node.

I want to use this modified texture in the compositor. However, when I use a texture input node and select the texture I made, I only get the default clouds, and none of the changes made by my other nodes.

How do I get the full results from the texture nodes?
