I have seen a lot of work where knotplot was used to make some very interesting formations that where then imported into bryce.  I have been playing around with KP for a few days and have yet to figure out the command to use to save the knot in a format that Bryce can then import in.  Has anyone used KnotPlot and can you tell me what the command string is for saving files? Thanks for your help.

Depending how the aplication windows are laid out,.......I usually go to the Knotplot Control panel, Export tab, and export as pfdxf(polygonal face dxf) or you can export as objout(wavefront object) but I've had some strange results using this method. Hope this has been helpful.

Great! This works well for one mesh but how do you tell it to give you a seperate mesh for each "rope"? 

Uhhh,..............dunno,.........sorry, don't use it that much.

You delete all but one thread of the rope and import that as a separate mesh and then either do that for each thread, or (my favorite way), take the one thread into Bryce and do a multireplicate to recreate the original knot.

That way, you can have a different texture on each thread.

It has been my experience when exporting an object from KP, I type the following in the command window:  objout xxx with the x being the name of the file I wish to give the object.  If the object that is created has multiple parts, the program exports an obj file for each part and automatically numbers it.  However, the numbering starts with 0.  So if I have a 3 part object, I would get something like this:  test001a0, test001a1, test001a2.  I find typing objout in the command window works the best for me. Hope that helps.   

I have imported the .obj output from Knotplot into Wings for further tweaking. Sometimes I just assign different material groups for further texture adventures in Bryce, or i like to select the whole object, do an INSET command, Then an inward EXTRUDE AREA, Then I assign the remaining selected faces with "Hole" material. Those faces won't be exported when you save it as an obj to import into Bryce. When you render it with a material of your choosing you'll see that its been "skeletonized". Sometime this looks even better if you subdivide(Smooth) once before export. Cheers, Dan
