Useful software tools and libraries (open source)

Animation

• Papagayo – lipsync animator, not up to JALI standards, but not nothing! However, not apparently under active development, and in C++.

Procedural assets

Textures

• Poly Haven – free textures, also HDRI lighting maps and some 3D models, although few look relevant.

Others

• Festival Speech Synthesis Text to speech library, in C++ but there’s a Java transducer.
• Mary TTS Text to speech library, probably not as good as Festival
