Importing a obj file in Silent3ditor

[JazzJR]

Hi,

I am trying to import a obj file in the Editor. I get it shown up but some verticles are invisible (in 3ds Max they are not) also the texture on it won't work. It turns up pink. How do i give it a texture in the Editor?
I always get the message

"The imported model is referencing 1 materials but the parent node has 0 material(s) assinged. As a result, the model may not be saved correctly and will likely be rendered incorrectly. Please add the correct material first"

Ok but HOW??

Anyone had this and solved it?
