Re: [osg-users] Offscreen snapshot.
Thanks for the replay. It doesn't work for me. It seems that there are some side effects: when I add the slave camera the screenshot from the main camera stop to work. I tried also with a composite viewer but... no: it doesn't work. Anyway: thanks fot the suggestion. I'll study more carefully the example.

[osg-users] Vec4Array for vertex array and the MatrixTransform transform is no longer applied.
Hi, I need to save an osg/ive file using 4 components for vertex positions (x y z and 1.0 for w). I need this so the texgen planes work correctly (if I omit w, for some strange reason, the texture gen planes no longer apply correctly). The problem now is that the matrix transform is no longer applied. Is like OSG is considering my positions already transformed. Is this is a know issue? Please refer to the attached file for an example of an OSG file. It contains 3 LOD for 2 terrain meshes. The vertex positions are 4D (with w == 1). As you can see both meshes are placed in the origin (one above another) as their matrix transform is no longer applied. For exactly the same file if .w is not present, the matrices are applied but my texgen planes no longer work as expected. Thank you!

Re: [osg-users] osgexport for blender?
I have been plugging away at this script and have a much better version now. See attached. It works well for my simple tests - but I don't have many example models to try. Animations are supported as well as textures (either image or generated). It does not support animated materials like the old script does (mainly because I don't know how to create them in blender). If you have problems and want to report a bug - including the model will be a big help. I would still class this script as unstable - mainly because I haven't done too much testing - but if you have problems I'm willing to try and fix them.

[osg-users] Maya2OSG patches
Hello all, I've attached small patches to two issues I've found with Maya2OSG. One allows it to build successfully with the current 2.8 branch - there are some manipulators not available in this branch so we just disable them by checking the osg version. The other issue was ambiguity in calling inTolerance, preventing me from building successfully on VC9 x64. I solved this two different ways: take your pick of which way you prefer. - I've made inTolerance a template function with a single parameter type and explicitly specified the template parameter in the one case. (fix-vc9-build) - inTolerance is a template function with three parameter types, and static_casts all arguments to the type of the tolerance parameter before doing math. This one doesn't require explicit template param specification, and seems more correct to me, or at least more explicit in how it works. I personally prefer this one.

If you could provide updated wrappers, that would be great. Thanks! Also, you mentioned some additional changes to osgconv. I'm still waiting on those.

Re: [osg-users] Maya2OSG patches
Thanks for the fixes. Changes are now committed to svn trunk. About the second issue, it seems a much complicated piece of code for what it's doing. I suggest this lighter and cleaner alternative instead of a template with three different typename parameters and the huge expression with four static_cast. #define inTolerance(base, match, tolerance) ( osg::absolute((base)-(match)) tolerance ) However, this part of the code was written by Peter Particle, so I'll redirect to him both proposals. Meanwhile, can you test if it is working for you right now?

One allows it to build successfully with the current 2.8 branch - there are some manipulators not available in this branch so we just disable them by checking the osg version. The other issue was ambiguity in calling inTolerance, preventing me from building successfully on VC9 x64. I solved this two different ways: take your pick of which way you prefer. I've made inTolerance a template function with a single parameter type and explicitly specified the template parameter in the one case. (fix-vc9-build) inTolerance is a template function with three parameter types, and static_casts all arguments to the type of the tolerance parameter before doing math. This one doesn't require explicit template param specification, and seems more correct to me, or at least more explicit in how it works. I personally prefer this one. (alternate-fix-build) These patches were made against the latest svn trunk of maya2osg using tortoisesvn.
