    I don't know. The link works just fine for me. It might be the browser you're using.

    Thumbs up

    That's a very nice tutorial. The technique of lighting the displaced canvas was demonstrated to me before I created the material baker script, but there's slight difference in how the lighting is baked using the displaced crop and fill method.

    Basically the difference is like the difference between lighting an engraving on a flat wall with only areas that are only slightly raised out or carved in rather than a full 3d sculpture you can view at any angle. The back of the head, for instance, will receive the same even lighting as the front.

    I think for skilled artists working with realtime engines, this even lighting technique will be better since they can paint in the highlights and shadows they want, and lately the lighting techniques and hardware has advanced to such an extent that trying to include highlights and shadows in the texture image to make things pop out more has been less of a necessity.

    For me, as a not so skilled artist, I always wanted to paint my model with uneven lighting and multiple lights lighting different parts to get some lighting variation though, so baking the model as like a 3d sculpture rather than an engraving on the wall was something I found necessary.

    There's another use for 3d baking however, and that is to leverage ZBrush's rendering and shading capabilities in another 3d package. You can do a 3d baking of a scene complete with global illumination, for instance, to one or more texture images, export the 3d objects complete with the baked texture images to another 3d package, and then just do a matte render of those objects in the other 3d package with the baked texture images and you'd basically get the same rendered result that ZBrush provides, and this should render in seconds for each frame because it doesn't have to do any radiosity or lighting of any sort. This is commonly done in archviz fly-throughs and level designs for games.

    This is one of the main uses for real 3d baking with uneven lighting, but the material baker is a very clumsy way of emulating it using multiple front projections rather than real 3d baking. Ultimately my hope with the script was for it to become semi-popular, but for its unavoidable shortcomings to create greater demand for real application support to allow real 3d baking.

    Great tutorial.
    However, I was hoping it was a way to bake the shader itself from within Zbrush.
    Is that even possible? ZB3 offers lots of improvements so it would be neat being able to transfer that data to a texture for furher editing.

    If anyone has a clue, tell please.

    Not only an excellent tutorial, (thanks) but also an outstanding bit of modelling too. One of the most sophisticated pieces I've ever seen here.

    Looks pretty awesome, but I'm unable to click the Create DispMap button for some reason (Yes, I am at the lowest SubDivision Level). It's just grey

    What format do you have to export that map as?

    Default Help with baking

    Hi, I am trying to use this method, but I am getting weird results. I used GUV Tiles to lay out the UVs, then I create a displacement map with these settings:
    DPSubPix= 2,
    DPRes= 2048,
    Adaptive= off,
    SmoothUV= On,
    Intensity= 0,
    Mid= 50,
    Mode= off

    Here are the pictures of my model high res with the material I want to bake, and a pic with the results of teh baking displayed on a flat material
