I started to learn Houdini several months ago (I even bought a new laptop for this). And because I learn best when I actually do something I took on this little personal project to try to do all. My first Houdini project. So, I tracked the camera in Nuke (I am using Nuke for compositing for a couple of years now), imported the FBX in Houdini and created the VFX of a torch with flame. I used also Solaris/Karma for this. I exported the VFX as image sequence and composited back in Nuke. 1/2
