Transfer from Lightwave 3d to EmberGen

I’m new in to this Forum, and new to use this great software,
I’m working in some 3d software , like Lightwave 3d and Houdini …
I want to ask about how can I transfer obj from Lightwave 3d to the EmberGen also from Houdini ,
I have Text logo and I want to use the Fire flame and smoke on it.
thanks all
