I have no clue what you mean by "Fatal nb colors error", it's just like a random collection of words put in a single sentence. This example of confusing or meaning free post is not unique amongst your posts, are large large percentage of your posts are really hard to pick out what you actually mean, and what the actual problem might be. The Language barrier could be part of the issue, I don't know whether this is a particular problem in your case, I certainly don't envy others in the world who ended up having to try to get support in a language other than their native tongue. I'm in awe of those out in the community at just how well a bunch of computer geeks get by despite English not being their first language. English is my first language and I struggle... If language is a particular problem then try to support your questions with pictures/models, copy and pasting the exactly warnings/errors you are seeing rather than trying to paraphrase as clearly this is failing as all too often you common out with sentences that are impossible to make any sense from. Also before you send any post take a step back, think about the problem you have, think about what information others would need to understand what you see in front of you, we aren't omnipotent, we can't see what you've done. This isn't the first time that I have asked you to put more effort into your posts to the forum, normally if had to provide such advice to members of the community in the past they fix the problematic style of posts and posts there after are much easier to follow and provide support to. This hasn't yet worked for you, so I'm a lost to what the specific problem is, why part of convey problems clearly is a struggle. Fixing this problem of communicating issues will be far more important to address than the immediate technical issue that you have in front of you. There will also be technical issue that pop up from time to time, you need to fix the communication issues. If there are specific reasons that your struggle on the communication front then tell us and we might be able to provide pointers. What we can't do is keep on with the current approach you have towards the community, it's painful for us, unhelpful to you, and is a poor example to the rest of the community.

I.e. you need the .mtl file with your .obj and the texture needs to be in the path specified in the .mtl Second, the error message about reversed faces means that your model has inconsistent winding order (clockwise vs anticlockwise). You should check that because it could mean that your normals will be wrong and faces get removed/culled by backface culling, making the model either disappear or have "holes". Conversion to .osgb won't help you any, because the converter uses the same obj loader as the viewer. So if it doesn't work with the viewer, it won't work after the conversion neither.

I had a similar problem with .ive files containing compressed textures, but named with .rgb extensions. I had to do basically what Robert is suggesting, though I don't recall whether I wrote a visitor to do the renaming or modded one of the plugins.

Re: [osg-users] osgconv.exe textures getting mangled
You are using compressed textures in the ive file, right? I figured out that the rgb plugin can't write compressed textures. The only pixel formats that are supported are: GLenum pixelFormat = img.getPixelFormat(); raw.sizeZ = pixelFormat == GL_COLOR_INDEX? 1 : pixelFormat == GL_RED? 1 : pixelFormat == GL_GREEN? 1 : pixelFormat == GL_BLUE? 1 : pixelFormat == GL_ALPHA? 1 : pixelFormat == GL_RGB? 3 : pixelFormat == GL_BGR ? 3 : pixelFormat == GL_RGBA? 4 : pixelFormat == GL_BGRA? 4 : pixelFormat == GL_LUMINANCE? 1 : pixelFormat == GL_LUMINANCE_ALPHA ? 2 : 1; When an compressed pixelformat (0x83f0) is encountered, it is treated as an unknown pixel format. And hence 1 is used for sizeZ... On Thu, 06 Aug 2009 14:42:03 +0200, Mach Bhai wrote: So how can this issue be resolved ?

Re: [osg-users] osgconv.exe textures getting mangled
No, it is not possible. The current osg implementation looks for the filename extension for the texture inside the .ive file. If the texture originally was an .rgb texture, it will try to write it to that format as well. On Thu, 06 Aug 2009 14:17:43 +0200, Mach Bhai wrote: Yes i am also getting rgb files.
