HiRes & LowPoly - Photogrammetry

An experiment on how to maintain high resolution texture of photogrammetry objects while still keeping the poly count low.

About

While photogrammetry can save a lot of time in the 3D modeling and texturing process, many times the Recap object has very high poly counts that make it difficult to use in many projects.

 

In order to decrease the poly counts, often the default Maya Transfer Map is used. However, with this option, texture information gets lost due to bad UV and shaders. In this project, I was able to achieve a low poly count with high texture resolution by applying specific shaders and re-UVing the low poly object.

My process:

  1. Imported Recap’s mesh to Maya and cleaned up extra noise.
  2. Exported Recap’s mesh to Instant Mesh as .obj to reduce the poly count.
  3. Imported the new low poly mesh to Maya and Re-UVed the object
  4. Changed all the materials of the original mesh from Phong to Surface Shader for the best baking/transfer result.
  5. Baked the original texture of Recap’s mesh to low poly mesh.
  6. Set the new material of the low poly object to Surface Shader.
