Hi Mark, << code.. >> I'll put some time into this over the weekend. I may not be able to do a lot of testing til monday though. Danny's done a lot of select/deselection, maybe he'll jump in too.

Hi Mark, I took a look at your problem and played around a bit. Here's a program that correctly selects/deselects objects in the 3D Editor and is selection-set sensitive. I hope it helps. Take care, Danny… /*________________________________________________________________________*/ /* Dialog description */ DlgEntry cdialog[]={ 0, "TITLE=\"Selection Test IPAS\"", 0, "TITLE=\"by Danny Mercurio\"", 0, "TITLE=\"Details, Inc.\"", 0, "TITLE=\"\"", 0, NULL }; /*_______________________________________________________________________ */ #define VERSION 0x0507 typedef struct{ ulong version; } State; ItemData data; static State init_state = {VERSION}; static State state = {VERSION}; int count = 0, counter = 0, status = 0; int verts = 0, faces = 0, result = 0, sel = 0; /*_______________________________________________________________________ */ /* declare global subroutines */ int selection_set(void); int set_object_selected_state(int select_it, int sel); int do_toggle_selection(int index); /*_______________________________________________________________________ */ int ClientUsesInitDialog(void){ return(1); } void ClientSetStateVar(int id, void *ptr){ OVL o; ulong *ul; char *s; ul = (ulong *)ptr; s = (char *)ptr; o.ul = *ul; switch(id){ } } ulong ClientGetStateVar(int id){ OVL o; switch(id){ } return(o.ul); } int ClientVarSize(int id){ switch(id){ default: return(1); } } char *ClientGetState(int *size){ *size = sizeof(State); return((char *)&state); } void ClientResetState(){ state = init_state; } void ClientStartup(EXPbuf *buf){ int result; /* requires version 3.0 */ if(studio_version() < 300){ gfx_alert(0, "[Resource Test PXP Plug-in requires 3D Studio Release 3 or later.][OK]", result); buf->opcode = buf->usercode = EXP_TERMINATE; return; } /* how many objects are in the editor?
