Owned by Adobe, Mixamo offers a massive library of free character animations. These can be easily imported into iClone 8 to expand your motion library instantly.

Because iClone 8 supports standard 3D file formats (like FBX and OBJ) via the integrated Pipeline features, your resource search doesn't have to be limited to the iClone format.

The Reallusion Content Store often features a "Free" category. This section includes community-contributed assets and promotional items from top-tier developers.

The safest and most reliable source for free assets is Reallusion itself. They frequently offer "Starter Packs" and seasonal giveaways to help new users get acclimated to the software.
