Trouble exporting texture to Meshlab
« on: March 21, 2016, 04:38:19 PM »
This may be more a Meshlab than Photoscan issue, but several times recently when I export an .obj model from Photoscan, when I import it into Meshlab, the texture will not import. The Meshlab message says:

Error encountered while loading file (xxx.obj).

Error details: Some materials definitions were not found , a default white material is used where no material was available.

The texture .jpg is in fact in the same folder, and I sometimes have models whose texture loads just fine.

As indicated, only the shaded mesh imports. I have tried clicking the UDIM option on and off when exporting, and fixing the topology of the mesh as well. Same result.

Any ideas?

Hello William,

What's the size and resolution of the texture atlas? Also is the texture/model filename is shorter than eight symbols?
Best regards,

As usual, thanks for the excellent user service, Alexey. I had tried both 4096 and 8192 without success. BUT when I just exported it as a 5-letter file name, bingo, it worked. So thanks for that! Hadn't noticed that limitation in Meshlab.
