This tool is used to clean shapes. When you clean the shapes the refresh of the scene will be better and will reduce the size on disk of the models and scenes.

This tool allows the creation of bounding volume objects through a selection. You can define if the new objects acquire the original transformations. You can create only one object with a multiple selection, or you can create one new object for each object in selection. It is also possible to create new objects with a subcomponent selection. With a polymesh subcomponent selection, you can create one new object for each subcomponent island.

RigIcon is a simple icon library for Softimage, a convenient tool to store and manage curves/animation-controls in your rigs [..] There's also a brief documentation and a pre-packed xsiaddon (archive) in case you don't want to mess with the source code, dependencies and so on... if you have no idea what I'm talking about take a look at the old preview.

You will need PyQtForSoftimage installed in your system, other than that everything should work fine OOTB. Cheers!

This is a collection of simple(ish) scripts I came up with packaged into a toolbar made primarily to make my workflow a lot easier. My main focus was on improving my symmetry modelling and making it a lot easier to quickly edit a fully rigged character (through the use of gator) without having to worry about anything. There is a small renaming bug outlined in the manual, if anyone has any tips on fixing that please let me know :)

SymmThings currently includes the following VBS scripts (individually downloadable on this pastebin page): Cloned Symmetry With Cutting Cloned Symmetry Create ShrinkCenter Shrink CL Cluster Scale CL Cluster Scale Component Reset CL Cluster Add to CL CLuster Zero X Delete-X Mirror Clone Mirror Instance Obj To Model.

For a video introduction of all the scripts, go here. On Alex's youtube page (link below), you'll also find a lot of useful tutorial videos mostly about character creation in Softimage.

This plugin use a json file as definition so you can add as many shapes you want.

Things to know: It have SRT offset and size parameters, and currently support only one closed curve per icon The icon.json file must be in the same directory than the dll (in the plugin folder), and the definition is a flat array of formatted like this [x0,x1,x2...,y0,y1,y2...,z0,z1,z2...] Performance wise, a quick benchmark showed that it's ~7% slower than a curve equivalent, but the good thing is that it has it's own type (Icon) and can be filtered The primitive is located in the create>primitive menu You need to install this It's not tested that much, use it at your own risk!!!

cgBreakdown creates breakdown keys, based on a percentage of the previous and next keyframes. Based on Justin Barrett's TweenMachine (a thing of beauty and a joy forever) for Maya . Very useful for blocking in stepped mode.

Respects marked parameters Handy quick preset buttons Can work on a whole model, or a single control. Whatever you've got selected. Fast! Full of object-model goodness.

Somewhat obsolete with Nuke's new FBX importer, but this will let you move .chan files between XSI and Nuke. Camera FOV values are used, if you've got a camera selected.

Will also work with Houdini, seeing as it uses the same .chan format.

Updated May 2013 (info) — Rewrite of the original QuickExtrude tool. This tool performs quick modo-like interactive extrude, bevel and inset operations without showing a property page. Piotrek's notes from the si-community thread: Extruding along normal is available only in 2012 SAP for operations that relies on SI units you drag in component's normal direction, for other ops (like point skirting ratio/bevel subdivisions) just drag across screen subdivision highlighting is supported only for level 1 and only catmull-clark J, L hotkeys change subdivision on extrude K hotkey is for repeating operation on highlighted component/subselection ENTER shows op PPG shift makes operations 10x slower LMB is extruding, LMB and then RMB - changes inset ratio of extrusion MMB is beveling, , MMB and then RMB - changes bevel subdivisions RMB is insetting tool can also work in supra mode if you hotkey the tool I've used it to model few production objects and it's pretty useful.

Developed with the interactive tool SDK. See Piotrek's video for a quick introduction

As demonstrated here, toggles between normal and slow interaction state, making object scaling/placement/rotation ten times slower than normal for temporary precise placement.

Installed as MCP->Transform->Transform precise and MCP->Transform->Camera precise (which does the same thing for camera orbiting).

Updated October 2013 with bug fixes, see here — Allows mass-editing of all referenced models' resolution (including »off-loaded«) and resolution path settings before loading the full scene in Softimage. Supports find and replace, multi-edit, file history, optional Softimage onOpenScene event integration.

This plugin works by modifying .scntoc files which Softimage saves along with every .scn Scene file and is particularly useful for scenes with many referenced models, like crowd scenes. Video demonstrations: Scntoc Res Manager v 1.02 Standalone / Scntoc Res Manager Softimage Addon

Updated April 2013 — read about the updates here. Species is a production quality character and rig creation kit based on Chris Covelli's »Grow Rig« system. From the product page:

Exocortex Technologies, in collaboration with CG Artists Chris Covelli and Eric Thivierge, is pleased to introduce Exocortex Species. Exocortex Species simplifies the process of human character creation from designing your character's unique attributes, integrating sculpting results, to rig creation, even animation. With Species, you will create higher quality animated characters faster and at a lower cost, while avoiding the generic look that often come when purchasing off-the-shelf models. [..] We'd also like to give credit to all of our awesome beta testers for the great feedback which helped us make an amazing plug-in. A special thanks goes out to Mitch Lotierzo for creating the custom Species synoptics. [..]

Price is $299 for individual/RLM-based licenses (node locked or floating) or $999 for a site license.

This is a custom Project Manager plug-in for Softimage. This is a more stable project manager UI for Softimage though it does not integrate with the built in file browsers. It uses an .sqlite database to keep track of the project names and file paths.

It's not meant to be a full featured well integrated tool but more of a base to build some pipeline tools off of. It uses the built in CreateProject() command to build the scene structure so it doesn't support custom project directories at this point.

Updated April 2013 — 5.3's main new feature TopoClipboard lets you copy map data from a point/edge/polygon/sample selection and paste it somewhere else on the same or a different mesh into a selection that has the same »shape« as the first selection. Also works for complete selections, which makes sense when pasting across two meshes that have the same topology, but differing point orders. TopoClipboard transfers: Vertex Colors UVs Envelope weights (with a remapping option) weight maps tangents point positions (local »shape« of the selected area). Works across different maps of the same type and across scenes inside one instance of Softimage. Other new features are a topology based mirror/flip selection and a couple of new settings for the custom filters like point position compare components, edge on UV border, edge orientation.

The RCTools plug-in is a collection of workflow helpers and filters for Softimage. The supplied popup menu (Script command »rcToolsPopup«) gives you quick access to all the tools. [..] List of features: Peek (Align camera along selected edge/facing selection @90°;) TopoClipboard Flip Selection Mirror Selection Fill Selection Walk Patterned Loop selections Apply Pattern Customizable Filters (by polygon area, aspect ratio, orientation, edge length, point distance and 30 others) subcomponent clipboard subcomponent clipboard booleans (e.g. Select intersection of current and clipboard selection) Cap holes Repeat

A render tree compound that renders worn/chipped off/colored/funny edges. Mental Ray only. But built from only a few factory nodes, so it should be fairly easy to reproduce this in other renderers.

The letters in the thumbnail were rendered by plugging the node's color output into a phong diffuse port, and into a bump map node at the same time. Let me know if you have issues/ideas about this shader.
