Cannot import texture maps from OBJ files

[brit_b]

I cannot import texture maps from OBJ files made with the latest Photoscan obj scans imported into latest ReCap Photo. (I was able to do so for a while with earlier versions.)

I'm not sure if this is relevant, but the mtl file in the OBJ he folder does not have a  "line 'Tr..." as mentioned in https://forums.autodesk.com/t5/remake-forum/import-a-obj-file-with-texture/td-p/6405123 in the Remake forum. 

The MTL file in notepad:

Ka 1.0 1.0 1.0
Kd 1.0 1.0 1.0
Ks 0.0 0.0 0.0
d 1.0
Ns 0.0
illum 0

newmtl Placa_Neri
Ka 1.0 1.0 1.0
Kd 1.0 1.0 1.0
Ks 0.0 0.0 0.0
d 1.0
Ns 0.0
illum 0
map_Kd "Placa Neri.jpg"

Additionally, as with the old Remake (intermittently... depending on the version and probably the version of Geforce), ReCap also is making my system slow, and nearly impossible to write on Google without rebooting the computer.

Any suggestions?

Would you mind sharing the obj file, the mtl file and the texture files with me ([email protected])? We will take a look, and it likely can be solved with a fix in the mtl file.

As for the slowing down of your system, we are investigating it. In the mean time, there is a workaround that can ease some of the pain. Change your screen resolution to anything different, apply and change it back to the default / preferred screen resolution. Your system should be back to normal (no restart required).

Hope this helps.

Thank you, Brit, for sharing the obj file with me. Managed to track down the issue. It is an issue in the OBJ file reader of ReCap Photo that does not deal well with quotation marks in the mtl file or obj file.

The quick workaround is to ...

1) Open the mtl file in a text editor and replace map_Kd "file name.jpg" with map_Kd file name.jpg i.e. remove the quotation marks.

2) Open the obj file in a text editor (I suggest sublime text or notepad++ as the obj file is large). Replace the first line mtl "file name.mtl" with mtl file name.mtl i.e. remove the quotation marks.

3) Save both these files and then open the obj in ReCap Photo. The texture will be loaded.

Another suggestion is to avoid spaces in mtl and texture file names when exporting the obj file from other software. If the mtl and texture file names don't have spaces, then the software exporting the obj file won't include quotation marks in the obj and mtl files ... and ReCap Photo should be able to consume the file as is (without the text editor changes).

Hope this helps.

 I downloaded notepad++ and this (the first solution) is a fairly simple work-around. I'm not sure how to manage the second solution without Photoscan re-writing its software. I hope that Autodesk and/or Photoscan can sort this out. My OBJ files made in Photoscan will open in 3DS Max without editing the files but not in Recap, so perhaps Recap can write something into its software so that it'll open in Recap?  But this first solution was very helpful in the meantime! Thanks!

I'm wondering if you could help loading a OBJ with textures on recap, I have checked you solutions on Autodesk knowledge network but unfortunately it does work for me as I don't see any quotations marks when I load it on Notepad ++. 

I'm sending the file through wetransfer to you and see whether you could help me. 

The file was created with photoscan and I will need recap to import the file in order to extrude a base for the model, which i have been told that it does, 

I have tried Meshmixer which seems great piece of software but unfortunately it do not work, it is simple to extrude but then I press accept and and an error comes up. I have emailed and send you the file. 

I hope you can help on this matter 

thanks in advance

I don't have any quotation marks but I still can't load 3D model with textures into Autodesk ReCap Photo app. There should be option to load a textures inside app itself, not only OBJ file. This can do some of free pay 3D model viewers.

I'm disappointed with that fact
