Hi, I have the following workflow:
- 391 images, High overlap alignment all registered.
- Reconstruction with normal quality -> Model with 10 parts, 11.2M tris
- Simplify to 500K, 9 parts
- Unwrap with following settings:

- Texture with following results:
texture_result.JPG

- Export to .obj as singleton
- Import to Blender. The result shows some edges on the texture where the parts are stitched together:
Edges.JPG

- I also imported to Unity to double-check, with the same result:
Edges_unity.JPG


How can I achieve a clean texture for my models?
Thanks for your input!

    Hi fhernand

    It is a BLENDER-related issue, how it handles MIPMAPS ( OpenGL 3D view ).

    Are you using JPGs for texture export or PNGs?

    Hi Wishgranter,

    JPG, I will try with PNG then. Seems to be also Unity-related, as I imported the .obj from RC into Unity.

    Just a short update, using PNG helped a lot, edges are almost gone now, but not entirely.

    Hi fhernand,
    I had once the same problem: I made an Action with Photoshop to extend the Edgepadding of the UV texturepads with one or two pixels with the pixelcolor of the edge.
