Re: [osg-users] set material basic question

Hi folks, I got a similar problem. Some parts of my model are always black. Despite setting the front and back color. @Shayne: I've enabled both ambient and diffuse color. And turning the model around (which changes the direction to the light source) doesn't change the color of the black

Thank you Shayne for the explanation. It does make sense. Gianni -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=43793#43793 ___ osg-users mailing list osg-users@lists.openscenegraph.org

Re: [osg-users] set material basic question

Hi All, I got the point. The vertex order of some faces of the wheel causes it. I modified one face of the wheel inverting the vertex order and after that modification I can see that face correctly coloured. Now, since I used the osg::Material::FRONT_AND_BACK option, why it doesn't work? In

Re: [osg-users] set material basic question

Hi Gianni, In addition to the combined flag, I just noticed we are also applying the material as close to the geometry as possible. Let's say you have a top level group node that is your root. The children of that group can either be geometry nodes or other groups. In our project, when

Re: [osg-users] set material basic question

...I hate it when I do this... What about PROTECTED states? Could the nodes that aren't being correctly affected by your material have a PROTECTED state, which prevents your material from being applied? See the thread Override of an Override for more information. Good luck... D.J. On Wed,

Re: [osg-users] set material basic question

Hi, again, Gianni... I think our design approach is largely due to the fact that we only wanted to apply our material to very specific parts of the scene graph, and applying a material at a group node in our scene might cause unwanted material changes in other areas of the scene graph. So, I

Re: [osg-users] set material basic question

Hi Gianni, On my project, we are using OSG 2.8.3, and we combine the osg::StateAttribute::OVERRIDE flag with osg::StateAttribute::ON. You might try: [code] root-getOrCreateStateSet()-setAttribute(material, osg::StateAttribute::OVERRIDE|osg::StateAttribute::ON); [/code] That combination seems

[osg-users] set material basic question

Hi All, I would like to set a color to a node that comes from an obj file (attached). Here is the code I tried. You can simply use it in whatever OSG example. Code: osg::ref_ptrosg::Group root = new osg::Group; osg::ref_ptrosg::Node scene = osgDB::readNodeFile(wheel.obj); if (scene.valid()) {
