Ky_Trail Pro – is the next generation of the popular free plug-in for 3ds Max – Ky_Trail, which was first released in early 2005. Professional version includes many changes and improvements. It is based on completely revised core, which supports multi-threading, and many new visualization parameters. Ky_Trail Pro is equipped with much faster algorithms. In particular, the render time of traces for a Particle Flow system was reduced several times.
Now in Ky_Trail Pro you can use vertices of geometric objects (including splines) as trail emitters. In combination with the ability to change the properties of the trails, depending on the parameters of the vertices (Soft Selection, Weight, Color) this allows to obtain an absolutely fantastic, easily manageable visual effects.
