Blender 2.77 Exporter Plugin - Mesh has no UV maps, material ignored


Recommended Posts

Hi guys, I've been hitting a brick wall the past 4-5 hours. 

Basically, I wanted to export a babylon scene containing a simple cube with a grass texture on it. Once i get the .babylon file, my goal is to have it directly imported into the BabylonJS environemnt, with the texture intact (or so I understood it).

I added some basic UV mapping (i chose the 'Flat Projection). I have no clue why the log file still says 'Mesh has no UV maps'

I have to admit, i might have messed something up here, but unsure what I did.


  1. Blender v2.77
  2. Exporter Plugin v4.4.4
  3. Babylon 2.3

Attached are my log files, my blender file, the grass texture, and some screenshots of my blender viewport (settings and rendered viewport).

I'd love to learn where I messed things up. If you have any advice/pointers, please fire away, thank you!

1) better.log (the log file)

 2) rendered viewport

7) the grass texture

Well cartman, a couple of questions.

1. With your "unwrapped" cube do you see the name of the uvmap in the box as illustrated with image 1? if you don't see an entry in that box - it is not unwrapped.

2. Which of the unwrap methods did you use - Image 2 ? I used  Smart UV Project to get the example in image1.

My quick test was done with Blender 2.76, BJS exporter 4.4.4 - and it worked fine.

cheers, gryff :)

Thanks @gryff, i followed your instructions (unwrapped using Smart UV Project, then added a grass texture). Now i get a new error in my log (attached).

   Image texture found, type:  diffuseTexture, mapped using: "UVMap"
    WARNING: Error encountered processing image file:  , Error:  '/Users/cartman/Downloads/grass.png' and '/Users/cartman/Downloads/grass.png' are the same file

Any ideas on how to fix this? Thank you in advance.

cartman, I have seen that kind of "warning" before - I think it just means that the texture you are exporting from Blender already exists in the directory you are exporting to.

How does your new babylon file look in the BJS Sandbox? 

Is it a textured cube?

cheers, gryff :)

@gryff i selected the grass.png and better.babylon from my folder, and dragged into the BJS Sandbox. I get the textured cube.

Thank you!

I also managed to import the better.babylon into my code, added a simple rotation animation. It appears that we need both the .babylon file AND the grass.png (my original understanding was I didn't need the grass.png at all - noob mistake :) )
