[SOLVED] How change color of scene

[Lev_a]

I want create night scene. But I don't want create real-time lights and shadows - it's really effected on fps. I just need made everything a little bit dark-blue. Like put mask on output window, but GUI - should be the same color.
I want keep:
ModelNode->setMaterialFlag(EMF_LIGHTING, false);
And I don't want use:
smgr->addLightSceneNode(...);
and
driver->setAmbientLight(...);

Could you maybe draw a 2D rectangle the full size of the screen and make it a seethru dark blue colour?

EDIT:
That won't work actually as it just draws the outline of a 2D rectangle.

maybe you oculd use draw2DImage and load a texture which is just a seethru blue rectangle?

I already think about it.
If any other solutions for it?
I found http://irrlicht.sourceforge.net/phpBB2/ ... 8831#58831
and I tryed:
ModelNode->getMaterial(0).AmbientColor.set(150, 50, 50, 255);
And no effect at all.

Any ideas?

I tried the draw2DImage thing but couldnt get it drawing see thru, just opaque.

My only other guess is that a shader might do the job.

Have not tried it (and cant atm), but check if you get it with:

Code: Select all

driver->beginScene();

SMaterial mat;
mat.AmbienColor.set(150, 50, 50, 255);
driver->setMaterial( mat );

driver->endScene();

UHM, sry; havent read you didnt want to use driver->setAmbientLight(...); [probably the same effect; OR MAYBE NOT, try and tell ]

Doesn't work - no any effects.
I just need put glasses on users eyes with color(.....).
I don't want use dynamic or other lights - I just want change color of air.
Any ideas?

I found solution:

Code: Select all

       driver->beginScene();
.....
        irr::video::SColor col = irr::video::SColor(50, 0, 0, 150);
        irr::core::rect<s32> pos = irr::core::rect<s32>(0, 0, 800, 600);
        driver->draw2DRectangle(col, pos);
......
        driver->endScene();

That's what i said in my first reply

Thanx, JP.
I could not read properly.
And I found "my" solution, but it's really your idea.
Sorry, for spam.
Topic closed.

um....sorry to bump this thread up but I have the same problem with the thread starter,create a night scene

I've read the solutions he made (actually, JP made it) but it just didn't work on me

I typed the code just as he showed in the previous post, like this

Code: Select all

			driver->beginScene();
			
			video::SColor col = video::SColor(50, 0, 0, 150);
			core::rect<s32> pos = core::rect<s32>(0,0,800,600);
			driver->draw2DRectangle(col,pos);

// some other rendering codes here

			driver->endScene();

but nothing happened, my scene still as bright as day

your help will be appreciated

The problem is you're drawing the rectangle before you draw your stuff, do it the other way around:

Code: Select all

			driver->beginScene();

// render scene here
			
			video::SColor col = video::SColor(50, 0, 0, 150);
			core::rect<s32> pos = core::rect<s32>(0,0,800,600);
			driver->draw2DRectangle(col,pos);

// if applicable, render gui here

			driver->endScene();

thanks! it worked!

I don't know how can I be so foolish about the rendering order, but now everything's fine!

thanks a lot!
