Why is the ground plane texture not exported from Blender

[DrYSG]

In the attached blender and babylon file. I tried to use inline textures to export a car sitting on a ground plane (PNG) which is 1416 x 2832 pixels (we need a large detailed ground plane).

 

But if I am reading the export log properly, the car textures were exported, but not the ground plane. I also do not see a ground plane.

 

I set an emission for the ground plane, and have a bright sun that lights up the car, but the ground plane is missing.

 

Enclosed is a screen shot of what it looks like in Blender.

First, in your zip the file m-city.png is neither in the zip, nor packed into the blend, so I can only look at the log above, and directly edit the .babylon using a text editor.

 

The mesh named Plane does show it found diffuse texture.  It is inside the .babylon file, on line 3.  It did not show, because the material had no ambient or diffuse.  I pasted ""ambient":[0.8,0.8,0.8],"diffuse":[0.64,0.64,0.64]" in place of what was on line 2 & it worked.

 

Not a bug.

Now looking at your blend, changing the diffuse color, from black to white on the Plane might fix the problem.  I do not know why since it is a texture, but if is a problem it is a BJS problem, not a Blender Exporter problem.

I did include the PNG, but not in the zip. I doubled checked blend, and I as shown below I think I am setting the diffuse. I am including a new zip with the texture enclosed. I do not doubt there is something simple I am missing.

 

In the zip is a screenshot of the blender settings for the material.

Yep, it was the black, material. It is now working fine. I just wanted no color on the texture. I figured black was good. No black is not a good material for textures (except in Blender).
