[SOLVED] [2.0] procedural material issue

[cinetec_tech]

hi:

   I currently have a procedural material problem and blocked. Hope someone could give a hand.

Here is how to reproduce my issue:

1:extract the attach rar file and put under data/ dir, open the test world, you should see the statues in depth

2:open system menu and set the anti aliasing to 4x (my issue only happen with anti aliasing on)

3: now press space to capture a image , it should be stored in the test1.jpg in the same dir under data

 

issue:

with anti aliasing on, the captured depth image is not correct as the viewport . if turn the anti-aliasing off or change the image resolution to same as the viewport looks ok.

in my case , i need render the viewport 2x or 3x larger than the viewport size while the anti-aliasing  has to be on.

I guess it should be some thing to do with viewport size function in the shader , but i couldn't figure it out.

thanks alot!

Hello there!

 

Thanks for the issue, looks like it's our bug. As a workaround you can make your own version of texture2DDeferredNorm.

 

So your fragment_filter_post1.shader will look like this:

#include <core/shaders/default/common/fragment_base.h>

/******************************************************************************\
*
* Direct3D11
*
\******************************************************************************/

half4 my_texture2DDeferredNorm(TEXTURE_2DMS s_texture,SamplerState s_sampler,float2 texcoord) {
	#ifdef MULTISAMPLE_0
		half4 deferred = s_texture.SampleLevel(s_sampler,texcoord,0.0f);
	#else
		uint width,height,samples;
		s_texture.GetDimensions(width,height,samples);
		half4 deferred = s_texture.Load(int2(texcoord * int2(width,height)),0);
		// half4 deferred = s_texture.Load(int2(texcoord * s_viewport.xy),0); // this was broken
	#endif
	return deferred;
}

TEXTURE_2DMS s_texture_0 : register(t0);

struct FRAGMENT_IN {
	float4 position : SV_POSITION;
	float2 texcoord_0 : TEXCOORD0;
};

/*
 */
float4 main(FRAGMENT_IN IN) : SV_TARGET {
	/////////////
	
	half4 deferred_depth = my_texture2DDeferredNorm(s_texture_0,s_sampler_0,IN.texcoord_0);
	float depth = getDeferredDepth(deferred_depth);
	return depth;
}

Thanks , that fix the problem.
