Nasa assets different in unity to blender

Questions & Answers
1

I am trying to use some of the 3d assets provided by nasa (specifically: Mars Global Surveyor | NASA)

I tried opening it straight with unity and it was untextured. I then opened it in blender and tried to package all the textures with the save file. Opening this in unity is better, however incomplete. For example the exhaust part on the bottom appears as a white cube, and the nice textured foil areas appear solid.

Should this be expected or should a blender model appear accurately in unity?

Materials/shaders in Blender won’t import to Unity. However, all the UV information will, so you can apply the textures in Unity and they will look right. You can export textures from Blender in the UV window, which may help.

You will either need to use Unity’s built in shaders or find Unity compatible ones. There are lots to get on the Asset store including some free ones.
Here’s the basic Shader info from the Unity docs.
