Tangent space baking via Nodes


nodes.gifEven though recently Tangent space normal map baking was added as a feature to the next version of Blender. This functionality is only available in special builds. I know many use only the official 2.45 build for production purposes. With that in mind you'd be without Tangent space normal map baking. Its possible you missed a solution provided at Blenderartists.

I won't go into the details on how it works. You can find that at the Blenderartist's thread.Its great that Tangent space baking will be available in the next version, thanks to the developers, but its also great we have a community that can make it work with what we have. Thanks community!


  1. Felix,
    the thread on BA is actually 3 months old.

    Not to denigrate the work of Zebouille in any manner but I'd like to point out that using the SVN is perfectly safe for some operation. Read me well, I said s-o-m-e operations. Normal map baking is one of them since the end product is a normal map that version 2.45 can use.
    So model a low poly in 2.45, sculpt a high poly in 2.45, save all that.
    Open in SVN, bake the normal, pack the texture.
    Return to 2.45 to use the normal map.
    Perfectly safe.


  2. I think the SVN trunk is pretty stable for the baking part. And you'd only have to bake the models once, since the 2.45 does SUPPORT tangent space normal maps.

  3. Yeah, using the SVN like it was an external app is perfectly safe, so making a bake or an autorig and then coming back to stable isn't dangerous at all.

    By the way, this node setup still is very useful in order to study the node system.
