ENABLE_TREE not working with view.material ?

ENABLE_TREE not working with view.material ? - 08/14/10 18:02

Hi,
i'm currently in the process of boosting my shadowmapping, refraction and reflection shaders and tried to clip away unneeded objects by using ENABLE_TREE and returning 1 in the material event.

So far, i couldn't get ENABLE_TREE to work with view.materials.

ENABLE_RENDER works fine, but in an older post you mentioned that using ENABLE_RENDER only gives a 75% performance boost, while ENABLE_TREE givs almost 100% (like NOFLAG1 does). So i'd rather use ENABLE_TREE instead of ENABLE_RENDER.
I also don't want to use NOFLAG1, so flag1 can be used for other things.

Am i trying to achieve something stupid here? Is ENABLE_TREE actually not working with view.materials due to a technical restriction?
When assigning the material directly to an entity, it's working just fine.

Here's my code:

Code:

#include <litec.h>
#include <acknex.h>
#include <default.c>

void v_camera()
{
	set(my,INVISIBLE);
	set(my,PASSABLE);
	while(1)
	{
		c_move(my,vector(key_force.y*50*time_step,-key_force.x*50*time_step,0),nullvector,IGNORE_PASSABLE);
		my.pan -= mickey.x;
		my.tilt -= mickey.y;
		
		vec_set(camera.x,my.x);
		vec_set(camera.pan,my.pan);
	
		
		wait(1);
	}
}


var mtl_dontRender_event()
{
	return(1);
}

MATERIAL* mtl_dontRender =
{
	flags = ENABLE_TREE;
	event = mtl_dontRender_event;
}

void main()
{
	level_load("");
	wait(3);
	
	you = ent_create(NULL,vector(0,310,746), v_camera);
	you.tilt = -90;
	
	you = ent_create(CUBE_MDL, vector(0,0,0), NULL);
	you = ent_create(CUBE_MDL, vector(0,100,0), NULL);
	you = ent_create(CUBE_MDL, vector(0,200,0), NULL);
	
	//this entity will not be rendered, works nicely
	you = ent_create(CUBE_MDL, vector(0,300,0), NULL);
	you.material = mtl_dontRender;
	
	you = ent_create(CUBE_MDL, vector(0,400,0), NULL);
	you = ent_create(CUBE_MDL, vector(0,500,0), NULL);
	you = ent_create(CUBE_MDL, vector(0,600,0), NULL);
	
	
	//create a second view which uses the dontRender material
	//this doesn't work
	VIEW* secondView;
	secondView = view_create(2);
	set(secondView,SHOW);
	set(secondView,NOCULL);
	secondView.size_x = screen_size.x/2;
	secondView.size_y = screen_size.y/2;
	secondView.material = mtl_dontRender;
	secondView.x = 0;
	secondView.y = 300;
	secondView.z = 760;
	secondView.tilt = -90;
}

I'm currently using NOFLAG1 as a workaround and it gives a nice boost for shadows. It would be nice if i could "port" my code to ENABLE_TREE

I'm using the latest A7 pro (also tried it with the A8 trial)

Thanks in advance! And sorry if this isn't a bug

Yes, that's correct. ENABLE_TREE is for entity materials only, not for view materials. I'll check if it can be implemented also for view materials - otherwise we'll mention this in the manual.

Good to know

I'll cross my fingers then that it'll work with view materials in the future

Apparently this wasn't possible to implement sadly, yet it's not mentioned in the manual either.
