Hiya all! Ive got a WIP snippet of a function to generate a BMAP 'preview' of an entity by filename. Sometimes its works and sometimes it doesent. By "works" I mean it creates a snapshot from a temporary view. And by 'doesnt work' I mean it renders to the BMAP OK, but the entity isnt visible... (or in the viewable area at least) And by sometimes I mean ... sometimes... I cant see any pattern. Run the script, hit the spacebar and ...nothi8ng Wait a few seconds, hit it again, and BANG! It works. But sometimes it will never work, sometimes it works first try. There is nothing special about the model, have tried with various ones. All behave the same way... Here is the complete script, just give it your own model in the 'test_1' function... (model should be smaller that 100 quants diameter to fit)
#include <acknex.h>
#include <default.c>
#define PRAGMA_PATH "Models\Mapobjects";
//
//
//=======================================================================================
//
function SnapShot_Event() { if(me!=render_view.genius) return(1); }
//
MATERIAL *SnapShot_mat = { event=SnapShot_Event; flags=ENABLE_TREE; }
//
//=======================================================================================
void preview_create(STRING* ent_name, BMAP* targ_bmap)
{ if((!ent_name)||(!targ_bmap)) return; //invalid capture parameter/s.
ENTITY* targ_ent = NULL; var old_mode=preload_mode; preload_mode = 3+4+8;
targ_ent = ent_create(ent_name, nullvector, NULL);
preload_mode=old_mode; if(targ_ent==NULL) return; //invalid entity name
vec_set(targ_ent.pan,vector(35,10,0)); vec_set(targ_ent.x,vector(-999,-999,-999));
//------------------------------------------------------------------------------------
VIEW *view = view_create(1000); view.genius = targ_ent; view.bmap = targ_bmap;
view.size_x = targ_bmap.width; view.size_y = targ_bmap.height;
c_updatehull(targ_ent, targ_ent.frame); VECTOR box;
vec_set(view.x, targ_ent.x); view.x -= 110;
vec_to_angle(view.pan,vec_diff(0,targ_ent.x,view.x)); view.material=SnapShot_mat;
//------------------------------------------------------------------------------------
set(view, SHOW); wait(1); ptr_remove(view);
ent_purge(targ_ent); ent_remove(targ_ent); beep(); }
//=======================================================================================
//
//
BMAP* targ_map;
//
void test_1() { preview_create("stair.mdl", targ_map); }
//
void main()
{
wait(1); level_load(NULL); wait(1); diag("\n\n\n");
//------------------------------------------------------------------------------------
//
targ_map = bmap_createblack(256,256,32); bmap_fill(targ_map, COLOR_BLACK, 100);
on_space = test_1;
//
while(1)
{
DEBUG_BMAP(targ_map, 10, 2);
wait(1);
}
}
Any ideas anyone???

Thanks Lukas, thats was it. Well, that AND setting the view flag back to ENABLE_RENDER instead of ENABLE_TREE where I had put it during testin.
And thanks Superku, or bringing the ONOENT flag to my attention, useful.
But I see other changes on there that make no sense to me.
Can you explain the reasoning behind them please?

Ah yes there are some other changes that don't have any effect on your problem, important are the following things:
// event for disabled camera rendering
function SnapShot_Event()
{
if(render_view == camera) return 1;
return 0;
}
...
targ_ent.material=SnapShot_mat;
// draw only targ_ent in "view"
view.genius = targ_ent;
set(view, SHOW | NOENT);
Btw. is this
vec_diff(0,targ_ent.x,view.x); // returns the vector pointer
valid, do all appropriate vec commands allow this?

Firstly, I missed Superku's question regarding vector functions.
"do all appropriate vec commands allow this?"
Anwser:: some do, some dont. Its worth testing them yourself because
some that do return the result vector ARENT shown as doing so be the manual...
Bloody 'undocumented features' ...

Back to the thread..... Its all gone up in smoke .... again .... Below you will find two scripts. The first is the 'entire' script for testing. It is utilising the SUPPOSEDLY fixed version of my original post. The second script is just the active portion of it that is utilising my version of Superku's solution. Both work fine as they stand. !! BUT !! I need to be able to turn the NOSKY flag on for that view/function. AND still have the screen-buffer (and z-buffer?) being cleared. I think! Reason being is that there is a sky-entity (ent_createlayer) that must be active in the camera view, but hidden in mine. AND the renderings of these previews want to be transparent where the background is showing through. Ive been d**king around for hours now, and just cant find a way. BUT I am a mere noob when it comes to handling views and view-materials... Also bear in mind, IN CASE it makes a difference, that there will potentially be up to 20 of these functions active during the same frame, and maybe overlapping. So, heres the scripts...

You will need to reset the PRAGMA_PATH to match your GStudio8 location, and create a folder called "@testing" in the folder where this script is, to capture all the BMAPS Im diagnosing with... Remember, both these scripts work perfectly as they are. Like this it produces the type of output I want (in the @testing folder). To get it to fail, you need to add the NOSKY flag to the "set(view,SHOW|NOENT);" at line 24. F1 -> F5 are one-at-a-time tests, but hitting the space-bar is the REAL test.

Simply set the client_id of your sky entity to the camera. Err ... what? I dont understand what you mean by this. Can you please give me an example of what you mean? Lets say that the sky entity is referenced by the global entity pointer ENTITY* sky_ent;Thanks dude...
