betty Posted November 4, 2002 Share Posted November 4, 2002 i am studying the old CHOPboat file that use to come with the OPexamples/demos. when i load this into houdini v5.5 i have no problems in playing it. but as i then start to rebuild this in another scene i have problems with the expressionCHOP. i get the error message - "unable to evaluate expression (unknown function in expression....." i then looked up angblend in the textport and couldn't find it in the current houdini but notice it is there in older versions like 4.1 i am wondering if this function has changed names or something. but i am a touch confused as there is no problem when i load the file but only when i reconstruct it. anybody have this problem? betty Quote Link to comment Share on other sites More sharing options...
