Hi Nigo,

According to the documentation, this form of texture definition isn't 
supported by the mesh object, which requires textures to be declared before 
using them in this context.
A simple workaround is to declare the object as a union of the individual 
smooth triangles whereupon it doesn't complain about the inline texture 
definition. (see the following example)

Where you said "but it doesn't work". It would have been better if you'd 
have listed the error message as the problem would have been quicker to 
diagnose.
