Rendering crash

We're getting the following when loading some imagery after cesium is intialized. We have a couple of different sets of imagery, so we load the imagery once the user selects which map to view. If you zoom in and out just after loading the map then the following will occur on occasion. We're also getting alot of the following errors, but we've been getting these for the length of the project.

GET http://<ip>:8081/default/smerc/2/2/3.jop 404 (Not Found)

Cesium.js:428 An error occurred in "_": Failed to obtain image tile X: 3 Y: 2 Level: 2.

Is there place to debug to see why this is occurring?

First of all, this issue is a real show stopper. I don't think we're doing anything outside of the norm, and it's pretty easy to get Cesium to stop rendering. Unfortunately, I can't really share our imagery, but I'm trying to find a way to build a sandcastle app to show the problem.

Cesium v28 on windows with multiple configurations.

Here is what I have done so far:

I changed:

UniformSampler.prototype.set = function() {

var v = this.value;

if ( v !== undefined ) {

var gl = this._gl;

gl.activeTexture(gl.TEXTURE0 + this.textureUnitIndex);

gl.bindTexture(v._target, v._texture);

} else {

console.info( "ERROR: UniformSampler value is undefined" )

}

};

And I got this(so I'm thinking that I'm on to something):

Any help would be greatly appreciated.

Thanks,

Scott

Another edit:

UniformSampler.prototype.set = function() {

var gl = this._gl;

gl.activeTexture(gl.TEXTURE0 + this.textureUnitIndex);

var v = this.value;

v && gl.bindTexture(v._target, v._texture);

};

Opps! Left out this part, same error as above though.

By "v28" Do you mean b28 or 1.28.0? (I assume the latter). We fixed an issue that could be the source of this just a couple of months ago: https://github.com/AnalyticalGraphicsInc/cesium/issues/4777 (and the PR https://github.com/AnalyticalGraphicsInc/cesium/pull/4811 ) .

I would recommend upgrading out 1.34 (which we just released today) to see if the issue still presents itself.

Sorry I don't have a better answer for you, but it's hard to provide more guidance here without being able to reproduce it on our end. I'm actually kind of optimistic that upgrading Cesium will fix the issue though.

1.34 does in fact appear to fix the problem! Thanks, Scott
