The question
Seems like a basic question: How can I show a 3D model together with textures? How can I embed textures? I worked with Wavefront .obj file but probably the principle is more general. I have a 3d object that shows fine, but without textures. In the end, I want to show the 3D model + texture in QGIS, but as the problem is linked more to 3D than to GIS, I hope to find a Blender-related answer here that then in the next step will help me resolve the QGIS problem as well.
The final intention (not the question here)
I am new to Blender and 3D modelling. My experience is with GIS and I tried to import a Wavefront .obj file to QGIS (OpenSource GIS) to visualize it in 3D. This works fine, at least when I visualize it with Shading
set to Realistic (Phong)
or CAD (Gooch)
. However, I want to visualize it using the textures that came with the file I downloaded. There is an option in QGIS to set Shading
to Embedded textures
. When I do this, the model disappers. I asked this question on GIS SE, but got no answer.
The problem here and what I tried
So I tried to open (import) the model to Blender (ver. 2.93.4, Win 10) to see if it works. The 3D model shows, but without textures. So obviously, my problem is to understand 3D principles and how to visualize (embed?) textures so that they are visualized together with the 3D model.
As for as I understand, the .mtl
file defines the path to the textures. However, I'm lost where to start and how to make the model to always be rendered together with the textures. To be more specific, I downloaded the file from here: https://www.turbosquid.com/de/3d-models/3d-farm-house-1594584 - it comes with a folder containing 3 files (FBX, mtl and obj) and a subfolder textures, containing 3 jpg files, see:
Loaded to Blender with Menu File / import / Wavefront (.obj)
, it looks like this:
the mtl file looks like this:
# 3ds Max Wavefront OBJ Exporter v0.97b - (c)2007 guruware
