v2 addons crash if 3D camera is used - RendersToOwnZPlane Issue

Hey all,

Maybe Ashley will see this. I am working on an sdk v2 plugin where I am extending ISDKWorldInstanceBase.

For my case, I have a working plugin where I render a 3D model using IRenderer drawMesh during runtime.

All works if 3D Camera is not used. Once 3D camera is added, the following crashes c3 once the object comes into view:

Uncaught (in promise) TypeError: Cannot read properties of null (reading 'RendersToOwnZPlane')

at C3.Instance.RendersToOwnZPlane (instance.js:1:5438)

at C3.Layer._DrawInstances_3DCamera (layer.js:1:27107)

at C3.Layer.Draw (layer.js:1:26170)

at C3.Layout._DrawLayerList (layout.js:1:24177)

at C3.Layout.DrawMain (layout.js:1:23029)

at C3.Runtime._Render (runtime.js:1:45802)

at C3.Runtime.Render (runtime.js:1:44962)

Looks like we need a way to set RendersToOwnZPlane to false?

Anyone have a work around to the above or is there a setting I am missing which would prevent this issue?

Note that simply using drawMesh during runtime works with 3d camera. In this case I believe it is an issue with the _sdkInst being null in:

RendersToOwnZPlane() {

return this._sdkInst.RendersToOwnZPlane()

}

Any help or knowledge on this is appreciated!

I used the sdk v2 example drawingPlugin addon to demonstrate the bug with 3d camera.

Thanks!
