It needs some properties exposed to tweak without events, even if you cant preview in editor, like:
Enabled (Checkbox)
X Offset
Y Offset
Z Offset
X Rot (0-360)
Y Rot
Z Rot
X SPD (positive & negative values)
Y SPD
Z SPD
It will make all more easy.Viewing post in Construct 3 Rotate 3D Behavior - SDK V1 only comments
It is open source, so you or someone else can make a PR to support this.
Also people can make a bounty for adding features like this on: https://opencollective.com/construct-community (I am trying to encourage c3 addon developers to use this service and do (paid) work for the collective.)
