    I’m applying some textures on runtime to a list of objects:
    object.material = new v3d.MeshBasicMaterial({map: texture});

    This works without any problems. But when this function is called again with the texture already applied, then there is a fast “blink” when the texture is getting reapplied.

    Therefor I thought to extend the function to check if there is already a texture on the object. At first I thought I could just use someting like:

    if(object.material.map.image)
//do stuff

    But because the objects I’m working with, sometimes are hidden. The function throws an error because it cant read the property.

    I’m therefor wondering what would be the proper way to detect if an object has a texture applied?

    Hi,

    I guess, that for those objects the object.material.map property is undefined. You can try something like this to fix it:

    
var map = object.material.map;
if (map && map.image) {
    // do stuff
}
