Some babylon.js 3D render using some simple JS integration with ElementQuad to integrate into C3 render and C3 events (you can put it on different C3 layers, add C3 effects, change size, position, etc. of the rendered 3d image.)
This is a template which uses C3 JS integration to add Babylon, it's not a Babylon add / plugin. It does use on plugin to show the results:
construct.net/en/make-games/addons/312/elementquad
You can also use C3 JS to access/manipulate the Babylon scene/engine, e.g.:
+ System: Every tick
| Local number alpha = 0
----+ (no conditions)
-----> System: Set alpha to ElementQuad.Sine3.Value
-----> Run JavaScript:
scene.activeCamera.alpha = localVars.alpha
scene.activeCamera.beta = 1.55+localVars.alpha/5
Babylon Template (requires ElementQuad addon)
BabylonTemplateLocal.c3p
Uses local project files for models / glb (works in preview and web)
