Re: [osg-users] Texturing issues second window
Hi Robert, Thank you for the tip, you are right. I used osgConv without optimisation on my original openflight model, and texture are OK in both windows (for ive and osg). If I don't want the optimizer to unref images, I have to remove OPTIMIZE_TEXTURE_SETTINGS parameter, but what might I loss in terms of performance without this parameter enabled ? 2008/9/5 Robert Osfield [EMAIL PROTECTED] HI Amalric, If you open the second graphics window after the first second graphics has been rendered and they share the same view, and the texture's are set up to unref images after apply, then only the second graphics window there will be no image to apply. If you have this particular combination of viewer usage then you will have to ensure you don't use the unref images after apply optimization in Textures - by default this is off, but the osgUtil::Optimizer can enable it, so perhaps this has been done from your .ive files, but not your .osg files.

Re: [osg-users] Texturing issues second window
We are seeing the texture problem in the additional windows for simple objects, ones that are not using paged LOD. It definitely seems to be related to the contexts but can't find the right settings to get it to work. What is strange is that, like I mentioned before, if we create the sphere and texture it internally, it works fine. But if I load a sphere with a texture on it, it will have problems in the second/third windows, giving the invalid enumerant error. Thanks again.
