The Canvas Tools Unity Exporter Plugin allows engine only developers to export GLTF scene files (.gltf/.glb) from Unity Editor, including all the supported component meta data.
The playcanvas-tools.js included with the Canvas Tools project includes a custom playcanvas-gtlf.js that supports the (soon to be official) GLTF Unity MetaData Extension i created.
I also submitted a PR to the playcanvas-gltf.js to add support for KHR PBR Specular Glossiness extension. That also allows GLTF implementations to FALLBACK to more of legacy diffuse workflow by using the PBR specular with a BLACK specular color and ZERO glossiness. So everyone using the playcancas-gltf.js can use that feature now.
But you can SOON use my Canvas Tools to Design, Script and Build you entire PlayCanvas Engine Projects directly from the Unity Editor using all the Unity Editing features like prefabs and packages.
Here is a sample screenshot of a Unity test scene. Complete with:
- Component Export
- Scripting Support (including TypeScript)
PlayCanvas Engine Only Project Using Canvas Tools:
ALMOST EXACT MATCH… THE ONLY DIFFERENCE… The quality of the reflection cubemap in Unity is a bit HIGHER and a bit more CLEAR than the PlayCanvas produced skybox_env.dds. That is because of the special DDS encoding PlayCanvas using for its reflections are a bit LOWER resolution and pixel format BUT IT RENDERS EVERYWHERE ON ALL DEVICES… RGBA32F WILL NOT. So i am pretty OK with the PlayCanvas rendered results
Still working on the Canvas Tools as a whole, but thats what i have planned for the PlayCanvas Game Engine Community.
Tons of MACKEY Game mechanics features coming, Like runtime prefabs, Terrain with splatmap textures export, navigation mesh export, and my awesome Mechanim-Like animation state machine that supports ALL the unity Animation Controller features, Like Transitions, Conditions, Blend Trees, Animation Events, Animation Behaviors and Custom Animation Curves.
NOTE: I really need some help with the 2D Freeform Direction and Cartesian Polor space game math. if ANYONE is interested in FULL animation export support from Unity to PlayCanvas… Please Hit me up… Help me make it ready for release
