Importing ODM generated OBJ textured model in Blender?

ODM
#1

Hi,
Thanks to all contributors for this amazing software!
I’d just fly and compute a drone map. 3D Textured model is very good.
I would like to simulate a camera moving in this model and generate a video that I could include in my own holidays video.
I exported the ODM’s generated model, and imported it in Blender 2.82. Unfortunately, Blender did not import textures… and displayed me a “moon” landscape!
Expected (WebODM View):

Got (Blender 2.82 View):

Does someone have some experience about importing OBJ textured models in Blender or in other software?

I haven’t had any issues importing into blender. You are doing a File:Import:Obj and you have all the texture files extracted?

Thanks for your positive answer.
Yes. I tried importing odm_textured_model_geo.obj and odm_textured_model.obj, but got the same result, without any texture.

MTL file contains only relative path… so it should be OK:

$ head odm_textured_model.mtl
newmtl material0000
Ka 1.000000 1.000000 1.000000
Kd 1.000000 1.000000 1.000000
Ks 0.000000 0.000000 0.000000
Tr 0.000000
illum 1
Ns 1.000000
map_Kd odm_textured_model_material0000_map_Kd.png
newmtl material0001
Ka 1.000000 1.000000 1.000000

What a fantastic dataset. It looks like it works fine:

Make sure to click on the “Viewport Shading” button:

It’s this button here:

And you may want to scale the model and add a Sun as a lighting source.

Good luck and let us know how it goes!
