I transform it into a sphere like you told me to, using this:

Code:
function cube_to_sphere(ENTITY* model) 
{
	
  int i = ent_status(model,0); 
  for (; i>0; i--) 
  {    														 
  	CONTACT* c = ent_getvertex(model,NULL,i);   
  	vec_normalize(c.x, 112);
  	c.v = NULL;   // set c.v to NULL	to change c.x,y,z 
  	ent_setvertex(model,c,i);
  	wait(5); 					 
  	}
  	
	ent_fixnormals(model, 0); // THIS PART OF THE CODE WAS ADDED AFTER READING THE PREVIOUS REPLY

}


The ent_fixnormals() worked out! thank you again for all your help fellow programmers!
