Okay, got the pbr to work, thank you

I’ve tried to figure out the preloader to show a ‘loading’ gif, but I’m still too much of a noob here. I see where you got the code from that GitHub discussion, but you mention ‘just showing a gif while it loads’. That’s all I want to do – is that a different thing? Do I need that ImageLoader() fix?

Is there a way to modify this to work with PBR textures? I tried it as is and it doesn’t work. Perhaps normal and diffuse textures are treated differently in PBR? Again, thanks for an excellent program.

Here is the link to the project:

If you want to see it without the buttons in front, the scene is here:
http://www.argosdesigns.com/ATI_Lobby/ATI_Lobby.html

It works on Safari, Chrome, and Edge, but it seems to simply not load in Internet Explorer.

It’s me again, and I tried copying the script over to a new version of the same project and I keep getting this error when I try to call the function:

[Error] TypeError: null is not an object (evaluating ‘obj.material.map.image = image’)
(anonymous function) (ATI_Lobby.js:131)
(anonymous function) (v3d.js:1:517256)

As far as I know I’m doing the exact same thing as before. Here is the function in ATI_Lobby.js:

app.ExternalInterface.changeDiffuse = function(objName, diffuseURL) {
app.scene.traverse(function(obj){
if (obj.name == objName) {

var loader = new v3d.ImageLoader();
loader.load(diffuseURL, function(image) {
obj.material.map.image = image;
obj.material.map.needsUpdate = true;
})
}
});
}

I went ahead with that, and it seems to work. Given that I’m still very much a noob with coding, I’m feeling very good about myself for making it work. Thanks again for all your help!

I’ve run into a problem, in that this changes the texture for every object in the scene that uses that texture, even if it has a different material. I plan to have at least 5 objects that would be swappable, do I need five different versions of each texture? I thought the objName parameter would mean that it only gets swapped for that object, as opposed to across the scene.

In the example, even the leftmost icons get the texture swapped out for the monkey head or gradient, though the other icons don’t.

Okay, this might sound counterintuitive, but I was able to get it to work. I had thought that I could make a menu pop up in front of the camera, with a bunch of icons by giving it an animation, and then when you clicked on an object, the animation would play. I parented this to the camera, right in front of the lens, but positioned down below where it would be out of the way.

Deleting this element makes it all work fine. Also, hiding it as the app loads works, then unhiding it, works fine. But for some reason the animation doesn’t work. Is there a better way to create an interface like I’m describing, or is this another Mac mystery? I can live without animated interface, just hiding and unhiding, but I’d rather have it animated.
