Re: [osg-users] Multitexture in Shader
Hi Linda, Did you ever get this to work? I'm seeing the same problem: Specifying multiple textures and then accessing them in the (fragment) shader always returns the data from the first texture.

Re: [osg-users] Multitexture in Shader
Hi, Linda If it works in your code, you can take screenshots with osgViewer::ScreenCaptureHandler (in osgViewer/ViewerEventHandlers header) without using osgscreencapture stuff.

It seems that only the first texture is successfully passed to the shader program. Any idea why it does not work? Or is there a way to pass multiple textures into the shader program and still able to work in the osgscreencapture code and to do screenshot? Thank you!

[osg-users] Multitexture in Shader
Hi, Has anyone encountered this problem where only the first texture at layer 0 seems to successfully passed to the shader code but not the other textures with textureID of 1, 2, ... ? Thank you!

Re: [osg-users] Multitexture in Shader
Hi, Linda Check if you set up texture attributes, modes and uniforms values for samplers correctly. Ex.: stateset-setTextureAttributeAndModes(0,textureOnUnit0, osg::StateAttribute::ON); stateset-setTextureAttributeAndModes(1,textureOnUnit1, osg::StateAttribute::ON); stateset-addUniform(tex0,0); stateset-addUniform(tex1,1); in shader: sampler2D tex0; sampler2D tex1; etc. Cheers, Sergey. 15.03.2011, 16:49, Linda Lee zenith...@hotmail.com: Hi, Has anyone encountered this problem where only the first texture at layer 0 seems to successfully passed to the shader code but not the other textures with textureID of 1, 2, ... ?
