Editing/Redrawing a texture in photoshop.

[agator08]

Hi Guys,

Please redirect this post if it's in the wrong place...i'm new =)

I've been using photoscan for a while now - I'm a geologist and I mostly create DEM's from airphots etc etc. Lately I created a model of a volcano from photos taken from a helicopter.

The volcanic structure is essentially a cylinder shape, with near vertical walls 500 m high and some overhangs...  Photoscan rendered a beautiful model + a great texture to lay on top. BUT I would like to completely recreate the texture layer and redraw/paint geology on top (I wan't to assign different colours for different rock types etc etc.

I'm a bit stuck on how to do this exactly. I realise I need another program, BUT getting it back into photoscan is a real problem.

So i've tried:

-Exporting Obj and opening in photoshop, painting texture....but I can't get the texture back into photoscan correctly. The texture map from photoshop is completely different from the one that photoscan reads...

-Exporting just the texture layer as a tiff, then editing in photoshop...this works, but it is VERY hard to do it correctly, as the texture map splits up the parts a lot!

Should i be leaving photoscan entirely and using another 3D editing software perhaps? I see video games where 3d structures have been drawn and completely constructed from scratch - this must be possible...!?

Any tips or workflow suggestions would be very much appreciated... d-day is approaching..!

cheers

Z-Brush, 3D coat or Mudbox ...

Meshlab and Blender could work too.

I was surprised to see a paint brush icon in Meshlab's tool bar. It does have some 3D paint functions, meaning you paint directly on the model, instead of editing the texture as an image like in Photoshop.
