I’ve got an issue creating a material on runtime. I get the error “Cannot read property ‘dispose’ of null” in the console.
However the application is running normal and the material is also created normally. But I would like to get rid of that error.

Maybe it has something todo with the 3.3.0 pre1 version I’m testing.

This is the code:

var video = loadVideo('./assets/Testvideo.mp4');
var singleObj = getObjectByName('Testobject');
var texture = new v3d.VideoTexture(video);    
singleObj.material = new v3d.MeshStandardMaterial({ emissive : 0xFFFFFF, emissiveMap : texture, emissiveIntensity: 0.7});

var video = loadVideo('./assets/Testvideo.mp4');

var singleObj = getObjectByName('Testobject');

var texture = new v3d.VideoTexture(video);

singleObj.material = new v3d.MeshStandardMaterial({ emissive : 0xFFFFFF, emissiveMap : texture, emissiveIntensity: 0.7});

Hi,
That’s strange. dispose happens when you’re unloading something. Are you sure these lines of code generate the error?

As soon as I got the last line for creating the material I get this error. At the moment the workaround I’m using is creating a “MeshLambertMaterial” instead of “MeshStandardMaterial”. With the lambert one there is no error, dont know why?

I made a simple test case based on your code, still no errors Can you share a link to your project sources?

I think I found the issue. I’ve upped the world cubemap res on runtime. As soon as I got the updateEnvironment in the code, I get the error with the MeshStandardMaterial.

This is the code in the runCode()

app.worldCubemapRes = 2048;
app.updateEnvironment(app.worldMaterial);

1 2	app.worldCubemapRes = 2048; app.updateEnvironment(app.worldMaterial);

This is the error log in chrome:
