Thanks for the reports. I created two new YouTrack items (RH-39000 and RH-39001).
By the way, what happens if you rotate the view after applying the material and it shows up black? For me it looks good after forcing the view to render another frame.
@Charles In order for the Box mapping to have any effect you need to set the Bamboo texture to use a mapping channel (not WCS Box which is the default for Material Library materials).
Puh, how complicated and misleading it is.
How should I know that I have to select multiple mapping channels if I want to use a single one only?
That is far too complicated.
There is only ever one mapping channel active for a texture.
Mapping channel 0 uses the texture coordinates on the object itself (surface parameters).
Mapping channel 1 uses whichever mapping that is set to channel 1 (in our case, the box mapping).
It is possible to have many mappings on a single object, all in different mapping channels.
The Bamboo material wasn’t using any mapping channels, instead it was set to WCS (box). That can be a bit surprising and unexpected, since new materials default to mapping channel 1.
