Zino54220 Posted February 25, 2014 Share Posted February 25, 2014 Hi gentlemen ! I need your help again... Like the title sai it... i would like import a mesh from Blender in Babylon.js with uv mapping. But with the material and texture, the mesh doesn't appear... and of course without the material and texture, the mesh appears correctly. I see that Blender have two kind of material options : "Data" and "Object".In first, I tried to create the material and texture with the option "Data" only, after with the option "Object" only and to finish with the two options but always nothing in Babylon.js... To create this material and texture, I took my inspiration of the exemple made by Deltakosh here : http://blogs.msdn.com/b/eternalcoding/archive/2013/06/28/babylon-js-how-to-load-a-babylon-file-produced-with-blender.aspx?PageIndex=2 But i don't see that I made wrong... because except the option "Use alpha" and "Diffuse", all of the checkbox are uncheked... I tried to chek many option at random but nothing better... So my request... Is it possible to have an exemple of mesh creation with uv mapping to import in Babylon.js from Blender? After my job, I will post my file or screeshot of my material and texture set up... Thanks you for your help !! Quote Link to comment Share on other sites More sharing options...
Temechon Posted February 25, 2014 Share Posted February 25, 2014 Hello Zino, It would be nice to share a live example of your problem, or the babylon file you try to import. However, my first guess is I think the problem is not from blender but in your texture path Are you sure the texture and the babylon file are in the same folder ? Do you have any errors in the javascript console ? Thanks Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 25, 2014 Author Share Posted February 25, 2014 Yes the files are in the same folder... I 'll try tonight to see if firebug see a problem with the path or anything else... I upload my babylon and blender files as soon as possible and I will put many .gif to show you my material's and texture's set up ... Thank you very much for your fast reply Temechon !

Temechon Posted February 25, 2014 Share Posted February 25, 2014 My pleasure I'm waiting for your files now Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 25, 2014 Author Share Posted February 25, 2014 Here, my files : Fichiers.zip So... - Striker_Tete_1_tex.blend is my Blender file with uv mapping, material's and texture's set up,- Striker_Tete_1_tex.babylon is my babylon file exported with the exporter of babylon.1.7.3.js ,- Striker_Tete_1_tex.png is my texture file created with uv editing of Blender and modify with Gimp. I precise many useful things (...maybe... ^^ ) - I use Blender v2.67,- In the link that I posted primarly, I don't see the sphere at the end of page... and I saw that Deltakosh speaks about drivers to anyone in a topic... Is it the problem ? Quote Link to comment Share on other sites More sharing options...
Temechon Posted February 25, 2014 Share Posted February 25, 2014 Nothing is wrong with these files.. Can you please try to upload the zip here : http://babylonviewer.herokuapp.com/I just did it and I can see this : http://i.imgur.com/HisHfFC.png When the scene is loaded, hit the 'back' arrow of your keyboard until you see the head. If you cannot see it, it sure is a problem with your computer... Quote Link to comment Share on other sites More sharing options...
gryff Posted February 25, 2014 Share Posted February 25, 2014 I took a look at your blend file and your babylon file. The blend file is fine except you have your model and camera way up above the baseline. In the babylon file is this code: "cameras":[{"name":"Camera","id":"Camera","position":[-0.0248,9.2411,-3.0183],"target":[0.0000,0.9958,0.0919], The Camera is 9.2 units up in the air but it is looking at a spot .9958 units up in the air - IE. it is looking down. Fix: Select your light, camera and model and drag them down so that the model just touches the 0,0,0 point. Now export your scene as a .babylon file. It should work. cheers, gryff Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 25, 2014 Author Share Posted February 25, 2014 Damned... I put a zip with my two files but I have an error "The babylon file cannot be found" ..... Then, more explication on my project... This mesh is a part of different meshes which are on a skeleton. Every mesh has it position calculated to be linked to the bone's skeleton interested (...the head's bone in this case...). So I don't think that is a problem of camera because I see all of my skeleton in my babylon scene... Normaly, I delete the light and the camera in Blender because I lead that in my babylon's code... I used it to do the verification of the uv texture position... With the post of Temechon, I think more that is a problem with my computer... Is it my graphic card drivers ??? I'm in spleen...

Temechon Posted February 25, 2014 Share Posted February 25, 2014 Damned... I put a zip with my two files but I have an error "The babylon file cannot be found" ..... Be sure to have a zip file containing directly the babylon file and its texture (no subfolder please ) Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 25, 2014 Author Share Posted February 25, 2014 I'm sure... Here the zip that I try to upload : Fichiers (2).zip In the meantime, I'm updating my graphic card drivers...(...get lucky...) Thanks you again for your help and opinion gentlemen Quote Link to comment Share on other sites More sharing options...
gryff Posted February 25, 2014 Share Posted February 25, 2014 So I don't think that is a problem of camera because I see all of my skeleton in my babylon scene... Well, the blend file only contains one part -what appears to be a head. When I apply the fix I described above this is what I see in the babylon sandbox: Without trying the fix above, load your babylon file and the texture into the sandbox - the screen will be mainly black. Now hit the down arrow key a couple of times - the model should appear. cheers, gryff Quote Link to comment Share on other sites More sharing options...
Temechon Posted February 25, 2014 Share Posted February 25, 2014 I'm sure... Here the zip that I try to upload : The zip contains a folder called "Fichiers". Remove this folder and it will work Or you can try the official babylon sandbox : http://www.babylonjs.com/sandbox/ Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 25, 2014 Author Share Posted February 25, 2014 Sorry my fault for the folder Yes it's good in the babulon viewer, I see my object...so why it doesn't appear in my game ?? There is many special code's lines for the RGBA texture ?? an boolean or anything like this ?? Or it's my version of babylon.js (v1.7.3) ??? P.S : I m using firefox and opera to do my test... of course it's the same result... Quote Link to comment Share on other sites More sharing options...
Temechon Posted February 25, 2014 Share Posted February 25, 2014 Can you share your code ? A live example on a dropbox or a google drive would be the best Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 25, 2014 Author Share Posted February 25, 2014 Ok I can send you my files by drop box or try to explain step by step with screen shot, gif and block code... as you want Quote Link to comment Share on other sites More sharing options...
Temechon Posted February 26, 2014 Share Posted February 26, 2014 Your files on a dropbox would be enough Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 26, 2014 Author Share Posted February 26, 2014 I send you tonight a compact version with my files Thank you again ! Quote Link to comment Share on other sites More sharing options...
Zino54220 Posted February 27, 2014 Author Share Posted February 27, 2014 Temechon find the answer ! The problem didn't came of Babylon or Blender but in my code... To realise an import I use the method : BABYLON.SceneLoader.ImportMesh("spaceship", "Scenes/SpaceDek/", "SpaceDek.babylon", scene, function (newMeshes, particleSystems) {});But my fault was that I write the path in the third param, like this in this example : ..."spaceship", "Scenes", "/SpaceDek/SpaceDek.babylon"... Babylon.js go to the folder "Scenes" to catch the texture but there was placed in "Scenes/SpaceDek/" for me... but without texture, the mesh displauyed correctly So be careful to your path in the seconde param. Thanks you again Temechon and gryff! Quote Link to comment Share on other sites More sharing options...
Temechon Posted February 27, 2014 Share Posted February 27, 2014 No problem Good luck for your project ! Quote Link to comment Share on other sites More sharing options...
