Re: [osg-users] OSG 3.2 and GLSL 330 light and shadows

Hi Solkar, I don't know how to do it; but sorry for the offtopic, have you been able to do custom shaders with shadows?? I want to combine bump mapping, specular and opacity with shadows. I tried it, but I couldn't. Thanks. -- Read this topic online here:

I agree on improving shadows. For example, 'advance' shaders (using attrib vertex) with shadows. Nick and I were talking about this a few time ago. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59456#59456

[osg-users] Differences between applying setStateSet in a Node and a Drawable?

What are the differences between applying setStateSet in a Node and in a Drawable?? I have a shader (BumpSpecularOpacity). If I set the stateset to a Node, it works correctly. But, if I set to a drawable it doesn't work. The stateset applied is the same. Any suggestions? Thanks!

Re: [osg-users] Differences between applying setStateSet in a Node and a Drawable?

Thanks Robert for your response. So, I don't know why it isn't working. This is the way that I configure the shader: stateset-setTextureAttribute(0, m_vGeoms[iContDrawable]-m_tDiffuse); stateset-setTextureAttribute(1, m_vGeoms[iContDrawable]-m_tNormal);

I think that what you should use is osgText::Text. There, you can do -setFont(font). font is the name of the font that you want to use. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59112#59112 ___
