See above. Is there a way to switch of Texture filtering in A7?
I want my textures to be as pixelated as possible laugh

d3d_mipmapping = 0;

there should be an entity flag

no, not mipmapping. texture filter. i want my textures pixelated, not smoothed.
like an ancient PC game or a psx game

Set d3d_antialias = 0; and d3d_anisotropy = 0;
and mip_flat = 5.0; (make the texture sharper, play with this value).
Scale down the Textures (e.g. 512x512 to 64x64) and you get the
oldstyle pixeleffect.

this sounds interesting. i loved old pc games like amok and doom

my textures are still blurred. on both level blocks and models frown

maby turing of mipmapping

d3d_mipmapping = 0;

Look in the manual for NOFILTER.

the manual states this works for models only. is there something like this for level blocks aswell, maybe a var?

Bugger. Well in that case I would personally use a shader that has disabled bilinear filtering in the texture sampler.

Using a shader might be a great way to get a better effect anyway, like if you want a similarly pixelated lightmap, or want to quantize the dynamic lighting to get a deliberate banding effect.

Import the level.wmb as Mapentity and the NOFILTER Flag is available.
to the textueres use a filter in your paintprogramm (mosaik or Facettes),
this make a pixeleffect on textures.

there was an option long ago in A4 but i guess thats out of the equation.
i neither need lights nor do i want to use a shader. i have my textures, so thats not a problem. i just wanted to know if there is a way to switch this damn thing off. map entities are out of the question.

you can also scale up your bitmaps without a filter in f.i. gimp. This way the textures will be less blurry in-game. But itīs a waste of memory...

Re: Switch off Texture Filtering? - 09/25/10 13:55

yeah. and also, they still will be blurry.
the nofilter flag woudl be perfect, since i already use it for my sprites and models. but it cant be applied to level geometry.
ive tried to export the level and import it as map entity (at least the parts that should use the flag) but it slowed down everything to below 20fps!!!!! so its also not an option...

You could use a view material like this:
Code:
MATERIAL* mat_old = {
	effect ="
	texture entSkin1;
	technique old_school
	{
		pass p0 {
			Texture[0] = <entSkin1>;   
			MinFilter[0] = POINT;
			MagFilter[0] = POINT;
			MipFilter[0] = POINT;
			Texture[1] = <entSkin2>;   
			MinFilter[1] = POINT;
			MagFilter[1] = POINT;
			MipFilter[1] = POINT;
			TexCoordIndex[0] = 0;
			ColorArg1[0] = Texture;
			ColorArg2[0] = Diffuse;
			ColorOp[0] = Modulate2x;			
		}
	}
	
	";	
}

...
camera.material = mat_old;

Code:
MATERIAL* mat_old = {
	effect ="
	texture entSkin1;
	texture entSkin2;//you forgot this one
	technique old_school
	{
		pass p0 {
			Texture[0] = <entSkin1>;   
			MinFilter[0] = POINT;
			MagFilter[0] = POINT;
			MipFilter[0] = POINT;
			Texture[1] = <entSkin2>;   
			MinFilter[1] = POINT;
			MagFilter[1] = POINT;
			MipFilter[1] = POINT;
			TexCoordIndex[0] = 0;
			ColorArg1[0] = Texture;
			ColorArg2[0] = Diffuse;
			ColorOp[0] = Modulate2x;			
		}
	}
	
	";	
}

...
camera.material = mat_old;

ahjhhhhhhhhhhhhhhh
that works.

but the problem i have now is that my floor just appears out of nothing before my eyes. walls and everything is fine, but the floor texture seems to materalize out of nothing. the whole floor is white and it just pops in, like a very close draw distance. funny enough, walls and everything are alright.

edit: forget the FPS part. error on my end.

Re: Switch off Texture Filtering? - 09/27/10 10:47

maybe you had some fog effect / sprite on the floor.
Posted By: sPlKe

Re: Switch off Texture Filtering? - 09/27/10 11:32

no fog, no sprites. as said, walls and ceiling are perfectly fine. just the floor...

Re: Switch off Texture Filtering? - 09/27/10 11:57

sounds like it's caused by mipmapping. is the texture size of the floor much smaller or something? try to change mipfilter to this:

MipFilter[0] = none;
MipFilter[1] = none;

indded, that did the trick!

thank you very much @ all, you were a great help. all is well now laugh
