Re: [osg-users] [osgPlugins] Trouble with texture to export to OSGJS format
Ok I will try to be clerarer: 1. Can you please share the ive model or a part of it to debug the crash? Otherwise is almost impossible to know what is happening. 2. Tga textures are not supported in the browser, you'll need to write them out to jpg. 3. You *must use the gles *pseudo-reader to avoid the Fatal nb colors. 4. Did you try the inline images feature? Did it work? Cheers. Well, I can show this very simple example with one IVE and 2 texture files. I cannot convert directly to OSGJS format. IVE -- OSGJS does not work (Fatal nb colors log) IVE -- OSG works OSG -- OSGJS does not work (Fatal nb colors log) OSG -- OBJ works OBJ -- OSGJS works but I have 2 logs saying that some faces were reversed by the plugin And if I try to load this model (with the textures in a folder \\images at the same location of the java script file) I cannot see the texture. Chrome moans: warning use white texture as fallback instead of images\tree_03.tga Thanks in advance !

I tried to use the gles plugin with the command described in the link you sent, but osgconv.exe crashes (no log message). Could you share the model, or a part of it to reproduce the crash? That will help to debug. I tried with an IVE and an OSGB files as input. So far the only way I have not to receive the error (Fatal nb colors 1 != 1349) is to get an OBJ from the graphist without texture. Texture files are in a separate folder /images.

That message means that osgjs is not founding the textures. Are you using a server like apache or similar? It is a must to work with separate textures, also the textures should be in the route they appear in the osgjs file. By the way did you try the inline textures feature?

[osg-users] [osgPlugins] Trouble with texture to export to OSGJS format
Good morning, I'm hardly trying to export a 3d model to OSGJS format but I have trouble with the textures. Concretely the textures do not appear in the OSGJS output file. What I did: 1) initially I had an IVE file that an infographist gave me. I tried the two commands osgconv File.ive File.osgjs. I got this return: Fatal nb colors 1 != 1349 can't save osgjs file Unable to write to output stream Idem with osgconv -O OutputTextureFiles File.ive File.osgjs 2) I tried (just for test) to convert the ive file to osg format. It works but the output file has no texture. 3) I asked the infographist to export the model to OBJ format with 3dsMAX. So I got an OBJ file and a MTL file. Then I do osgconv -O OutputTextureFiles File.obj File.osgjs I get some warnings such as *** line not handled *** :map_refl C:\myFolder\myFolder2\maps\refmap_txt.jpg Warning: [ReaderWriterOBJ::convertElementListToGeometry] Some faces from geometry '' were reversed by the plugin Strange because the JPG file really exists in my fodler ! I have other JPG files and I have no warning message for them. Anyway, I do not think it is the source of the problem. But the final OSGJS does not appear with textures, as no texture is exported. The geometry is correct. Apparently I did something wrong, but I don't know where ! If someone has an idea about this export issue ?

Re: [osg-users] [osgPlugins] Trouble with texture to export to OSGJS format
Hi Mathieu, You should use the gles plugin to export to avoid the Fatal nb colors error. See: https://github.com/cedricpinson/osgjs/wiki/Convert-model-with-OSG. For the images: You can try to convert first your model to osgb and write the textures to disk and then convert to osgjs using $osgconv file.osgb.gles file.osgjs, if the osgjs plugin is not writting to disk the images. Also you can save them as inline images in the same osgjs file. The resultant file will be bigger though, but it is ok for quick tests. For example drag dropping here http://webkeux.com/osgjs-test/ One more thing, if you have the images as separate files you *must *use a server (http server I mean).
