Hi David,
Just found out that the fault lies in my 3D model. Apparently, my shader only
works for 3D models that are in OpenFlt format. It doesn't work for ive fomat.
I've appended my shader code below:
uniform sampler2D tex;uniform float fAmp;
void main(){
vec4 texelColor = texture2D(tex, gl_TexCoord[0].st);
texelColor = texelColor * fAmp;
gl_FragColor = texelColor;}
Thanks,
Cg

PROTECTED]: Re: [osg-users] Shader ProblemHi CGWhen your remove a shader, "void
Program::dirtyProgram()" is called to request a relink in the next
frame.Program is relinked in the next frame in "void Program::apply(
osg::State& state ) const" method.Follow your code in a debugger to see if all
is properly done.Are you sure your shader is well removed from your program
?HTHDavid Callu

hi CGwhen you remove a shader, osg::Program need to be relinked.this is done by
osgUtil::GLObjectVisitor in osgViewer::Renderer::draw method.So this seem can
be done at runtime.Which OSG version did you use ?Did you use osgViewer ?David

Hi all, Are there any ways to remove the shader during runtime? I've tried the
removeShader function but the effect of the shader is still applied to my
models (e.g tank) i.e. the appearance of the models do not go back to the state
before shader is applied. Regards,Cg
