AC3D ships with a Milkshape ASCII exporter, but it only exports the geometry and doesn’t export the animation rig. This plug-in supplements the existing exporter by adding an alternate export option “Milkshape ASCII (With Skeleton)”. This allows you to export to Milkshape ASCII format with the skeleton and materials intact.

Download the plugin. (Requires Windows XP, AC3D 6.2 or above.)

This plugin exports your AC3D file into NMF format, the native input format of the ATI NormalMapper utility. NormalMapper allows you to generate normal maps, bent normals and ambient occlusion maps suitable for use in video games and other realtime 3D applications.

If you aren’t familiar with normal maps, normal maps are a way to make your low-polygon model look more detailed by encoding surface information from a high-polygon version of the same model into a texture map. Ben Cloward has an excellent tutorial where you can learn more.

This plug-in requires the free NormalMapper utility available from AMD in order to process the output files. The companion NormalMapperUI (Stand Alone) available at the same location is also helpful, but not required.

This plugin “bakes” a texture from one object to another, allowing you to transfer texture data between two models with the same geometry but different texture coordinates–without having to re-paint the texture bitmap! This is useful if you start to paint a texture, and change your mind later about the UV map; or for games when you can’t change the layout of the map for technical reasons, but would like different UVs for convenience during painting. It’s also good for fitting text onto a warped surface or other projections that would be difficult or impossible to paint by hand.

This plug-in collection adds a series of tools to AC3D that allow you to manage object pivots more effectively. With this plug-in set, you can: Set an object pivot to the highlighted vertex, zero the object pivot, rotate around the pivot instead of the centroid (numerically), or manually enter a pivot location. These functions are very helpful for setting up your model for animation or import into games.

New for AC3D! This plug-in adds quick reload to the tools menu, allowing you to reload all your textures in just one click. It also includes a tiny disk monitor client that automatically notifies AC3D when your texture maps are saved to disk by your paint program. With this plug-in, you can see your changes made in Photoshop, Corel or your favorite paint program show up in AC3D right away–without any additional clicks.

* UPDATED 5/14/2008: New version with faster reload! This version tracks textures more intelligently to prevent the same texture from being reloaded more than once per cycle, even if it’s used multiple times.

* UPDATED 11/27/2008: The texture monitor is now obsolete. As of 6.4, AC3D now includes its own, much better texture monitor.

Download the plugin. (Requires Windows XP, AC3D 6.2 or above. Disk monitor feature requires TCP\IP loopback support for communicating with AC3D.)
