I might not have explained myself clearly, and actually have made 2 questions in one. I´m attaching the snapshot for to facilitate things. First of all, I have this low-res sample from which Nuke´s camera tracker has given me a surprisingly solid track. (I have disabled the camera tracker node to avoid the point cloud to obscure the plate in the snapshot). Now, in Nuke X 6.0.1 there is a ParticleSystem node. I would suppose somehow you link it with the cloud points to make it work, and you feed it somehow with whatever you want the particles to be generated from. But nothing happens and, as you can see, the help is not very explanatory. I might be making a silly question here but I just don´t know how you use the ParticleSystem node and have not been able to find much info about it. There´s no info about it in the manual. Also, some people have published custom particle system nodes but neither have I been able to install them and make use of them. There´s one in this very site, but I haven´t been able to install it. (I think there´s a mistake, it reads it´s for Nuke 5 and then for Nuke 6, the installation notes seem to correspond to Nuke 5)

So my first attempt was to export the camera tracker information and do the job, or part of it, in After Effects. But Nuke exports a chan file, which After Effects doesn´t read. That´s why now I´m kind of bound to use the Boujou-AFX pipeline. Which is a shame cause nowadays I´m very comfortable with Nuke and would prefer to do the whole thing with it.
