server sets EF_MOVER_STOP bit if basi stops
   legs.hModel = ci->nonSegModel;
   legs.customSkin = ci->nonSegSkin;

   if( es->weapon == WP_ALEVEL1_UPG )
   {
     //ZOMG UBER HACK
     if( es->eFlags & EF_MOVER_STOP)
     {
       if(!cent->invis)
       {
         cent->invisTime = cg.time;
         cent->invis = qtrue;
       }
     }
     else
     {
       if(cent->invis)
       {
         cent->invisTime = cg.time;
         cent->invis = qfalse;
       }
     }

     if( cent->invis)
     { //fade out in 1 second shader time is 0
       legs.shaderTime = cent->invisTime/1000.0f;
       if( cg.time - cent->invisTime < 1000  )
         legs.customShader = cgs.media.invisFadeShader;
       else
         legs.customShader = cgs.media.invisShader;
     }
     else
     {
       if( cg.time - cent->invisTime < 500  )
       { //fade in in .5 second :: shaderTime is 2 - .5
         legs.shaderTime = (cent->invisTime+500.0)/1000.0;
         legs.customShader = cgs.media.invisFadeShader;
       }
     }
   }
and the corresponding shaders are

gfx/invisfade
{
 {
   map models/players/level1/level1upg.jpg
   blendFunc GL_ONE GL_ONE
   // sin wave of amp 1 and base 0 (usual sinwave)
   // starts from .25 -> PI/2 -> sinx = 1
   // .5 cycles per second -> period 2 second
   rgbgen wave sin 0.0 1.0 0.25 0.5
 }
 {
   animmap 24 gfx/invis.jpg gfx/invisa.jpg
   blendFunc GL_ONE GL_ONE
   tcmod scale 2 2
   tcMod scroll 0.2 -0.2
   //tcGen environment
 }
}
gfx/invis
{
 nopicmip
 {
   animmap 24 gfx/invis.jpg gfx/invisa.jpg
   blendFunc GL_ONE GL_ONE
   tcmod scale 2 2
   tcMod scroll 0.2 -0.2
   //tcGen environment
 }
}

I want to learn if there is a better way of fading shaders manually or another way of doing this
This works good so far ie when you stand still basi becomes invisible slowly and when you move it appears again a little faster
