  1. Cool stuff David! Is that a pig skull?
    I can imagine you putting this on a tray for the camera shooting.
    I like modeling things by myself, but I must admit that photogrammetry results
    are amazing!
    Are the thin cracks on the skull captured while shooting or did you add them
    in the paint room?
     

  2. Thanks Wojtek! I managed to get descent volumes combining your technique
    and Carlosan one. Importing image as a mesh takes a little effort, because it's hard to tell
    what will be the height of the mountain with a range going from pure black to pure white.
    Tweaking "Bump thickness" helped more than working on height map subtle values.
    The density and the mesh size created by "import image as a mesh" seem to be
    screen based. With the same texture I get completely different things depending
    on my camera being close or far from world center.

    Now I have to think of buildings or aircraft to put on the scene and give an idea of the scale...

    Thank you for your help. That's fun to try something new!

  3. Carlosan! Thank you for the tip!
    I can't get a nice detail definition on the mesh though.
    The "Import Image as a Mesh" is a good workflow shortcut. It takes not much time. I like it.
    But I didn't found options to chose the voxel definition. It gives me a 0.6 density model
    whatever I do.
    I tried the stencil way described in Wojtek thread. Even with a 4096X4096 stencil texture (height map)
    and X16 definition mesh (26 millions polys) the result is too rough.
    I can't tell if it is a lack of density or if the height map that is not subtle enough.
    Also, trying to build a very wide area at once is may be not a good idea. I'm gonna make a
    few other tests with one stencil for each mountain rather than trying to build the whole scene at once.
    Well... may be the fail is due to something else, but I just don't get it for the moment.

  4. It does work!
    Thanks Wojtek! Never thought of this workflow in 3dCoat though I used it in Maya long ago.
    Still, I found it hard to figure out how high is the mountain while painting over the stencil from above.
    Being able to extrude it all at once like when you load a height map in Maya would be cool.
    The result on the pic is still rough. I guess I have to rework the grey scale map.
