Puzzle challenge – wine label visualizer

Just had a quick look at your puzzles, so i might be reading it wrong, but It looks to me like you are trying to assign the textures(or “state”?) and not the materials when you press the texture 1 and 2 buttons, so changing tex1 and tex2 in the two top puzzles “groups” with Tex1Diffuse and Tex2Diff in the assign material puzzles should help i think. Also it looks like you are updating both materials with the new texture when using the upload button, i guess you would want to separate that out to one event for each button. Hope that makes scense … if I´m thinking correctly here …

I think you only need to use the send data node if you actually need it to go to the web server, and the opened file would just be “cached” in your browser if not.

Don’t know how you set up the materials, but indeed you should be able to manipulate parts of it, like changing textures if there is a texture node in your material setup, which looked to me like it was working in the link you posted

So the simplest would be having a material applied to something out of sight, and them swapping that into the label object once “uploaded”.

Just experimented a little bit with the texture swapping and opened file feature so far, so I might be slightly of on some things here. But i hope this helps you out a little, and the Verge3D team can probably fill out some details if you need.

Hello again. So I just had to try this, and this is what I came up with(see attachment).

I tried to keep your setup for the most parts, just moved some things around and added some outlines to the “buttons” so you could see which “texture slot” was selected at any given time. The top group also sets the Label to the first material right away and enables the outline.

So there are 3 materials;
-One to hold the default material to start with (material0, not used in the puzzels)
-Material 1 to hold texture number 1 (material1)
-Material 2 to hold texture number 2 (material2)

The three planes under the box is just to show of the three materials as you change stuff.

One thing that surprised me, but makes real sense, is that if you have the same texture in all materials, even if the materials are individual, the reffarance to the image seems to be the same, real handy if you got the same texture used multiple places and just want to change all at once, so you see the textures have an extra number at the end just to make them individual.

I hope this is useful to you, if not at least I learned a couple of things ;)

You can test the “final” project here;

Push the gray boxes behind the text, I did not bother making the text itself clickable or align the text to the buttons for that matter, but i think its clear enough for a little demo :)

Did not see your last post before I posted. Not sure if you could store it in a variable, my solution was to use the material to store it in a way, using a variable might be better if that would work, at least for some more complex scenarios.

yes, you are right! Puzzles in the init tab are initialized even before the WebGL context is created. The other tabs are executed after the main .gltf file is loaded.

You could also then set up the first custom tab to be you own “init afte sceneload” in a sense then, assuming the tabs will always be processed from left to right … !?
