Rhino imports OBJ with Custom material instead of picture

I import SKP file, then export it into OBJ. After opening that OBJ, instead of showing normal textures, it shows solid colors. Then I realize, that Rhino renders materials as Custom, not as Picture. How can I fix this? I don’t know, maybe in other programs my OBJ will reflect in normal way, but it’s really annoying to have this view in Rhino.
Here is the video:

Here is the SKP
01.skp (1.1 MB)

Here is the OBJ
001.obj (2.6 MB)

Thanks in advance.

Hello- for obj to find textures, the texture images must be provided in the same folder as the obj and mtil files.

How can I locate the pictures behind these materials?

However, if I import SKP file, even in that case, Rhino forces SKP materials to be Custom, not Picture.


Even after I copied the SKP pictures to the OBJ folder, Rhino still understands these materials as Custom, and if I want my OBJ to be normally texturized, I must change every single material into picture and select picture from the folder.

It’s not an optimal way and takes too much time.
