    How can I add these generated submeshes to the objects

    coding

    I created a procedure to extract the names (not 3D objects!) of submeshes and add them to the list of measurable objects, and now everything is as expected!

    Thanks for the help!

    Ok Got it thanks!
    Also it gave me the opportunity to tune your puzzle block to add a scale option fore these ends. Everything works fine now!

    I do not see where to put this code… dimPointOne is only defined within the enableMeasureTool function.

    Ok but there is no option for these line ends as there is for the labels… Do I have to hard code it in the puzzle code??

    And another one: it seems that there is an issue with multimaterial objects. In the puzzle object selector they are represented with an “empty” icon whereas the monomaterial objects are represented with a standard object icon.
    And it seems that the measure tool does not recognize these objects (as they are indeed “parent” object with children geometries attached to them).
    How can I add these generated submeshes to the objects to be taken into account for the measure tool?

    Ok Great! thanks
    We loose the “always on top” behaviour but that’s not a big issue for me…
    Another quick question: how to increase the scale of the dots and arrows at the lines end??
    Thanks!

    Hi Kdv!
    I’m having an issue with your measure tool, more precisely with the line(s) material which seems incompatible with the material I am using.
    The consequence is that the lines are not visible when an object with my material is somewhere behind the measure lines.
    When the material has some transparency we can see the lines “through” the material (blue cube in my example), but as soon as there is a mesh with this material in “opaque” configuration the lines disapear (transparency is controlled by the material alpha attribute in my material).
    Any idea how I could fix this? Does this have to do with the renderOrder in some manner?
    Thanks for your help!
    The example is here:

    Thanks @kdv!
    The material on which I would like to activate gtao is not an emission shader.
    GTAO can actually be activated on it as I can do it manually by changing the gtaoVisible parameter in the .gltf file before loading the application.
    In fact this parameter is false by default because the material has a transparency (alpha blend) which can be controlled by the user. Most of the time the material is opaque, and then it looks much better with GTAO, and in some rare cases the transparency is used, and in those cases, the problems related to GTAO in use with transparency are not really an issue for me… so I would like to be able to change this gtaoVisible parameter for this material after loading of the gltf file, and be avle to see the result in the viewport.

    I’ve tried to enable it manually with js code. I managed to retrieve the correct material, and write the gtaoVisible parameter to “true” but I see no effect on the viewport… I used the following code:

    const material = v3d.SceneUtils.getMaterialByName(app, "NI_paint_vertex_color")
material.needsUpdate = true;
material.gtaoVisible = true;
console.log(material)

    I can see in the console that the parameter has been set to true, but no visual change…

    The easiest way would be to publish the App on the Verge3D network, but I have a 500:Internal server Error when I try to publish it. The Application folder is located outside the “normal” verge3D application folder and i use a symbolic link… any way to get it to upload properly??

    Thanks Alex!
    I’ll try to pack something that reproduces this behaviour…
    And lastly, is it possible to change this gtaoVisible parameter after the scene loading? (from false to true) and to update the material in order to display with Ambient Occlusion?
    Thanks!

    Also Alexander: is there a way to control or change this parameter, either in Blender before the gltf export, or programmatically with some javascript? I don’t see any reference to this parameter in the developper reference…

    Yes. That’s it! :scratch:
    If I try to activate the HiDPI option on some of my gizmo objects (e.g. xy plane move and Z-rotate), these two objects have the issue = not showing, whereas all the other objects with the same material and no HiDPI option are showing properly.
    And the issue is not systematic as I mentionned earlier. It can show properly from time to time, without any reason.

    I think I may have found something, which is perhaps a bug. It seems that it has something to do with the “HiDPI compositing” option for the objects that has this material.
    When this option is active, an object with this material which shows up properly at the initial loading of the 3D scene can disappear after a few orbiting and change of point of view! Absolutely no other interaction with the object itself, and no puzzle related to it.
    Disabling the HiDPI option seems to solve the issue…

    Hi Alexander!
    Thanks for the info.
    I am completely lost right now… I’ve got a material which sometimes shows up properly, and sometimes does nos show at all. I do nothing in between these cases except refreshing my web page, with exactly the same steps…
    Here is a capture of the material:

    I use this material for a grab/rotate gizmo which is supposed to show when I select an object. the color is driven by the vertex color of the mesh, and I use the Object Index to drive the intensity of the emission (when the object is dragged, it is highlighted). Everything was working fine until now, and I cannot identify what can cause such an unpredictable behaviour.
    Same gltf file, same binary file, same js files, and after initial loading, sometimes the material shows, sometimes it is not! No error message in the console. No clue… I’m lost.
