Re: [osg-users] osgShadow texture problem
In attachment osg file that doesn't work. When I activate osgShadow, I can't
see texture.
In osg file there's field textureUnit 0 {}. If I remove this and change,
texture works.

Re: [osg-users] osgShadow texture problem
I find the problem: some models (made in Maya and exported in Collada then in osg), in osg file have texture 0 empty. Perhaps in shadowed scene this is an important value. If I remove empty texture and I change other texture numbers it works. Have you got some ideas about this? thanks -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36529#36529 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgShadow texture problem

Re: [osg-users] osgShadow texture problem
Hi, with some shadow techniques they take base texture unit value, try setting that value. Maybe that will help out. Are you rendering in Shaders or Fixed function pipeline? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36488#36488 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgShadow texture problem
Hi, I put sm-setTextureUnit(1); but it doesn't change. I don't know if it's rendering in Shaders or Fixed, how do I check it? I can't understand why some models works and others not. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36496#36496 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] osgShadow texture problem
Hi Daniele, It could be that some models are using multi-texturing or are the state in the models doesn't work well with the shaders used by osgShadow. The best way to work out what the different models are doing is to export then to .osg or .osgt (if you are using 2.9.x or svn/trunk) and then have a look at the resulting ascii file as it will list all the state that is being setup, and what texture units are active.

Re: [osg-users] osgShadow texture problem
I'll add that (at least in version 2.8.3) changing the texture unit for the shadows does not update the shadow technique's shader code. You'll have to override the default shader code to align with whatever texture unit you choose to use for the shadows.
