I don't know exactly how I should do to "create a custom UV parametrization to apply to mesh" into Blender (maybe it means I have to define a regular surface projection) but I don't understand why I have to "import mesh back" to PhotoScan and to "build texture in PS using keep UV option".Īgisoft support team told me they can't help me beyond this tips because they have experience enough in "UV mapping" and they recommend me to visit the forum where I saw your post.Īnother idea about I was thinking, it was to unwrap a dense point cloud (XYZ coordinates) into UV mapping (XY unwrapped coordinates) but I didn't know if this was possible untill I saw a post of a user who got to "unwrap" a dense point cloud trhough Meshlab and VisualBasic codes.
#Unwrap 3d model cylinder how to#
I ask to Agisoft support team and they told me the next workflow: build mesh in PhotoScan, export mesh, open it in Blender (or similar 3D editing application), create custom UV parametrization and apply to the mesh, import mesh back to PhotoScan, build texture using Keep UV option. There are many topics relating to flattening or unwrapping that I have been pouring through all morning but I'm having a hard time understanding how to leverage sheet metal tools in order to 'unwrap' a surface or flatten a body, specifically how to set up my surface/body in order for the sheet metal. I am trying to unwrap the UV unwrapped texture of the vault through Blender but I must to assess the accuracy to know if acceptable. I was training with a frescoed barrel vault to studying for future applications in maintenance tasks of the paintings stamped on the intrados vault, so I would like to obtain the unwrapped model (UV unwraped mapping) of the textured vault which I have got previously with Agisoft PhotoScan. I have a problem similar to the tunnel of Geophotologist:
