Watermaterial scoping / code-structure issue (vr)

Questions

Hi,

I’m continuing to hack the babylon vr physics example, and continuing to work through what I imagine is the difference between “scene as promise” and “scene as scene object” (I have posted about this before).

You can see a demo here, the scene is getting pretty interesting: https://twitter.com/delta_ark/status/1336454691471835136

I was able to implement the water/object material in the “setup” function of my code, but when I implement the same code as a function that one of my agent calls, I get this error:

babylonjs.materials.min.js:16 Uncaught TypeError: Cannot read property 'clipPlane' of undefined
    at r._reflectionRTT.onBeforeRender [as callback] (babylonjs.materials.min.js:16)
    at e.notifyObservers (babylon.js:16)
    at t.renderToTarget (babylon.js:16)
    at t.render (babylon.js:16)
    at t._renderForCamera (babylon.js:16)
    at t._processSubCameras (babylon.js:16)
    at t.render (babylon.js:16)
    at (index):3323
    at t._renderFrame (babylon.js:16)
    at t._renderLoop (babylon.js:16)

index line 3323 is the following:
if (sceneToRender) {
3323 --> sceneToRender.render();
}

I have isolated the problem to one line of code (336, it’s inside one of my agent’s functions):

waterMesh.material = water;

When I console log waterMesh and water, they both show up; so, I’m not sure why I can’t set them to each other.

In the past, I have gotten my other agent function code to work by referring to the scene as createScene.scene. So, I’ll create a box and attach it to createScene.scene, and then everything works in the agent function.

Feel free to look at the code here: Glitch :･ﾟ✧ . Again, I can’t put it in a playground bc the code is too large at this point; it’s a full VR game.

Help with getting this water material stuff to work would be really appreciated.

OK, and just nailed it.

the scene must be “sceneToRender” inside of the encapsulated f(x)
