-set Octane as renderer

Note that we do not use Enable Particle Interface in this case.

-in tyFlow001, 'Open Editor', in 'Event_001', select Mesh, and uncheck 'Render only'
(Alternatively, create a tyMesher, set to tyFlow001)

This allows to generate a single mesh from the particles.
The UV mapping of individial particles is not yet supported in Octane.
