Is this the proper place to report errors?

I have been updating and modifying an Ocean Wave Generator. My program is [here](https://codepen.io/Phil_Crowther/pen/KKxozaR) on CodePen and has been updated to r150.

I have been making some minor changes, one of which was to add back a SpecularFactor. To show the sun, I added this simple subroutine:

```javascript
	// Sun Object
	let geoSun = new THREE.SphereGeometry(64, 16, 16);
	let matSun = new THREE.MeshBasicMaterial({color: SunCol});
	let mshSun = new THREE.Mesh(geoSun, matSun);
	scene.add(mshSun);
	mshSun.position.x = 5000*sunLightPosition.x;
	mshSun.position.y = 5000*sunLightPosition.y;
	mshSun.position.z = 5000*sunLightPosition.z;

```

However, if I run the program in Chrome on r150, the sun does not display and I get a three.js shader error (although the program otherwise keeps running). If I downgrade to r149, the problem disappears. I don’t see any obvious changes to r150 that would cause this.

- [Here](http://philcrowther.com/WebGL/Seas/JBouny_r149n_pen2b.html) is the program that uses r149.
- [Here](http://philcrowther.com/WebGL/Seas/JBouny_r150n_pen2b.html) is the identical program that uses r150.

It lists the following errors with three\_module.js:

ERROR: 0:165: ‘textureLod’ : no matching overloaded function found  
ERROR: 0:165: ‘textureLod’ : no matching overloaded function found  
ERROR: 0:166: ‘textureLod’ : no matching overloaded function found

This issue should be fixed by using `0.150.1`, see [Shaders: Move bicubic texture filtering to transmission chunk. by Mugen87 · Pull Request #25563 · mrdoob/three.js · GitHub](https://github.com/mrdoob/three.js/pull/25563).

Yes, that fixes the problem. See, e.g., [this example](https://codepen.io/Phil_Crowther/pen/xxaazOL).  
Thanks for the quick fix and for all your efforts at making three.js a truly versatile program.
