Hello,

Using Poser 8's Material Nodes, I would like to draw a line on a given surface. My goal is to have a tear roll slowly down a figure's cheek in a Poser 8 animation.
 
I want to specify the width, length, and direction of the line with Material Node parameters.

I plan to use a Blender node to add the drawn line on top of a bit-mapped texture, and eventually, I hope to use the Frame_Count node to lengthen the line within a P8 animation.

Is this feasible? I would appreciate a pointer to a tutorial or any helpful suggestions to get started.

Thanks,
Richard
