FESRetopo - retopology tool for Softimage

Plugins linking to this thread: (hide)

FESRetopoAuthor: Shekn @si-community
updated to 0.75, information about update can be found here — A retopology tool built with the Fabric Engine - meaning it will run in other applications like Maya and Houdini as well. Note that it's using a Softimage specific initialization plugin (installed in Create > Polygon Mesh > FESRetopo), so in other applications it would have to be initialized manually.

Shekn's description from the si-community thread: There are three parameters: Reference - The path to the hi-poly file. Hide reference - when checked, the hi-poly reference is not drawn in the viewport. Hide HUD - when checked, edges and points are not drawn in viewport in case the splice manipulator is disabled (for example, when rotating the camera).

In fact, the global purpose of this tool is to build the analogue of Topogun for Softimage and take the retopology process of some small models inside one 3d-program without import-export actions.


An interesting timelapse is available on his Angel07's channel: Ear retopology sample, as well as installation instructions: FESRetopo tool.

Some description: this is retopology tool for Softimage, It based on FabricEngine, so it should be installed too. May be the tool will work with old versions, but current 1.15.x is recommended. The core of FESRetopo consists from splice-operator and some extensions. So, it can be used also in Maya. For Softimage I additionally create some python script for automatically execution. So, after installation you will obtain item "FESRetopo" in Create - Poly. Mesh section

There are three parameters:

Reference - path to hi-poly file
Hide reference - when it checked, then the hi-poly reference is not drawing in the viewport
Hide HUD - when it checked, then edges and points are not drawing in viewoprt in the case of splice manipulator is disabled (for example, when rotate the camera).

In fact the global purpose of this tool is to build the analogue of Topogun for Softimage and take retopology process of some small models inside one 3d-progarm without import-export actions.

ha! Just yesterday i was thinking about retopo in Softimage!
The idea was to create retopo based on weight map.
-paint low-poly wire to weight map
-emit particles base on weight map
-poligonize them
-apply relax deformer to smooth down this blobbed net to a wire.
-remove doubles
-dissolve vertices with 2 edges connected.
-fill wire with polys (dont know if SI can do this, but was intended to export resulting wire to blender , which does)
This gives pretty good results, but painting weights on a dense mesh is no fun in softimage :(

I dont have splice installed, but there is alot of code in KL files. I think same functionality in SI C++ API would be like 5 times shorted. Hope most of those kernel language commands were generated automatically base on a few visual nodes :)
Anyway, great plugin, and can be used in Maya also. Just to much code... Bad Fabric Engine, bad! :)

Make some improvements, and now it works much faster.

And yes, if try to write the same tool in c++ API of Softimage, then the number of lines in code will be the same (more or less). The main part of this code belongs to logic and does not depend on Softimage API or FabricEngine API.

Great - thanks for sharing the source code also.

The next 0.7 version update.

Download: https://dl.dropboxusercontent.com/u/114 ... %200.7.zip

Some sample videos:
1. The process of sphere retopology. All new tools used.


2. More complicated case of the eye area.


3. Ear.


Whats new. The most important - new three tools:
1. Edge tool. Allow to create an edge between two points. Also allow to extrude an edge and form a 4-sided polygon. Convenient to create polygon loops.
2. Move brush. Simple move points.
3. Relax brush. Smooth the wire.

Also there is a short manual in the archive with pictures and descriptions of tools.

And yes, all done for Fabric Engine 1.15.3.

Very cool! Love that relax tool :)

Definitely will have a go with this.

Great indeed,

And nice to see fairly complex Fabric things working in soft!

One of the recent Fabric clips (presented by Mr Mootz) shown a fabric genereated mesh deformed by a lattice, so at first glance it seems to play well with layered operators (most probably including ICE 'operators')

In any event Congratz and useful indeed! (in whatever app :) )

Working great! Thank you so much for this tool. Its very exciting to see Fabric tools keeping the community alive.
