I designed a home interior and it includes wooden floor also. I used the UV/Image Editor to generate images to draw home interior in Open GLES but I failed to generate the image.

Another problem is that the Texture Coordinate array is not complete, that means many numbers of the coordinates are not available in the array it only shows comma separated blank spaces(using obj2opengl.pl to generate the array). I added an example image, I have to generate images like this. enter image description here

  • $\begingroup$ Could you add a part of the .obj file? Just to see Blender export is correct, when the obj2opengl script omits the values it would be off-topic here. $\endgroup$

Blender exports the .obj file correctly I can't see a reason why empty values ",,,," are written in the converted file.

mtllib Musium.mtl
o Plane.275_Plane.229
v 138.827621 -14.357000 -71.175812
v 145.607269 -14.357000 -71.175812
v 138.827621 -14.357000 -123.266418
v 145.607269 -14.357000 -123.266418
vt 0.882195 0.266138
vt 0.983474 0.328281
vt 0.122201 0.759672
vt 0.020922 0.697529

It seems to be a bug/issue in the obj2opengl.pl converter possible it expects optional values which do not occur and therefore it writes empty values (between the commas).

I would recommend to write your own exporter, to get started you could use the code I posted here: How do we access Vert, Norm and UV data then print to a text file using Blender/Python?

  • $\begingroup$ This can be done by texture painting or cloning (e.g. images) into a single texture this should be another question (needs space to explain). $\endgroup$
