  • Hi , Mikal when you have a spare time it would be nice to have an example of this plugin working with the new C3 3d camera , thanks

  • This is an awesome idea, id love if construct could integrate some sort of basic 3d model system, like blockbench, thats a great program, items or characters. It would be fantastic to be able to use those models in construct, my 5 year old uses that program to make minecraft blocks and conplicated stuff is easy as its all based upon cubes, just luke construct 3s 3d shapes. :D keep up the great work

  • Wrap my had trying to import my 3D object from blender.

    Can you please say more about how obj got to be done to use in the plugin?

    I tried many different tutorials but without success

    Also, please give a little more info how placing objects is working.

    For example, if I wrote path to box.obj from your example, in the new 3Dobject object, then became impossible to use other files from inventory, box model always will be shown

  • found the issue. we got to restart the game to make changes in the model

    ....

    another thing

    you got to bake texture in the blender to make it visible in the 3Dobject

  • Right, this is not easy to do! I am finding 3D models, blender, animations are difficult to work with in general (even beyond this plug-in.)

    I am leveraging some work that r0j0hound did and hope to get GTLF file formats working for this plug-in, instead of obj/mtl. That being said, I have also found that getting a good gtlf embedded file is also not that easy!

    Here's an example of GTLF import (still WIP, not ready to release yet.)

    is it skeletal animation from blender?

    dreams come true...

    really great work!

    and each, everybody using gtlf files for the html5 3D this days

  • What weird thing i found, if to use 3Dobjects with construct 3D camera it makes models distorted

    Look at steve, he is got to be as a box

    so, will be good to have the ability to change x,y,z scale separately

  • we need zelevation property for the 3Dobject.

    to make possible collisions.

    because now we can check x,y coordinated only and without z we can collision in the Z dimension

  • Thank you a lot

    will try it asap

  • Nice plugin! I would love to make a small demo for this plugin but I have no idea what I'm doing wrong. I added "test.gltf" under "Files" and tried to define the location of the file in the 3dObject, but the model doesn't load in.

    I tried defining the file as "Files/test.gltf" and "test.gltf" but neither worked.

    I changed project settings to use the 3d renderer, but the 3d model won't show.

  • Check the dev console for errors. Otherwise, carefully follow the instructions on how to add a 3DObject to your project. Also, test out your gltf in the Babylon sandbox.

    My model shows up just fine in Babylon.js

    However, I do get the following error message upon filling in the gltf file path,

    and I made sure I set rendering mode to 3d:

  • Is the gltf file you’re using one of the ones included in examples for this plugin?

    I helped with the initial gltf loader part of the plugin. The plugin should be able to load any gltf file saved as embedded from blender, or any other program.

    With the gltf format it has three different variations:

    Gltf + bin

    Gltf embedded

    Glb (binary)

    The loader in this plugin only handles the embedded variation. Which seems like the format you’re using since it works with the Babylon test bed.

    Anyways if you’re able to share the gltf file or a c3p project with the file it may help to find the issue.

    From the error it looks like something isn’t loading correctly.

    Mikal

    It may be something as simple as the the exporter that made the gltf file not adding all the properties that the plugins loader expects. I thought it follows the spec but this may be a case where if that part isn’t there you’d just add it from the other info in the file.

  • I did add ignoring some missing elements R0J0hound, but I definitely did not do an exhaustive check of a lot of gltf files. Thanks for all the initial work though!

    Mattertainment how about uploading the gltf and png files, so we can take a look? (I use sendgb.com for quick temp file sharing.)
