Clouds Edge Noise

[werner.poetzelberger]

Hi, 

I have tried a lot of settings, following the video tutorial etc, but I still have nois occuring on the edge of clouds, which I cannot get rid of.

There are several layers intersecting each other, camera is inside cloud, and so on.

There is the sample count which makes the noise finer, but it does not disappear. On EXTREME setting I still have that (image).

I just want blurred edges.... But I cannot seam to achieve that.

Is this an overall setting in the cloud rendering or in the material?

Hello!

Werner, to make clouds noise less visible you need to edit "data\core\shaders\clouds\compute\compositor.comp" shader

Please look at 84 line with "Samples count" settings and increase each value per few times

// Samples count settings
#ifdef SAMPLES_COUNT_EXTREME
	#define SAMPLES_COUNT_MODIFER 2.5f
#elif SAMPLES_COUNT_ULTRA
	#define SAMPLES_COUNT_MODIFER 1.5f
#elif SAMPLES_COUNT_HIGH
	#define SAMPLES_COUNT_MODIFER 1.0f
#elif SAMPLES_COUNT_MEDIUM
	#define SAMPLES_COUNT_MODIFER 0.5f
#else
	#define SAMPLES_COUNT_MODIFER 0.25f
#endif

Be aware it might affect performance depending on how much you increased the counters.

You can also add blur effect to "data\core\shaders\clouds\fragment\scene_copy.frag" shader, see "core\shaders\screen_space\fragment\blur.frag" as a reference.

Basically, looks like increasing the "SAMPLES_COUNT_MODIFER" value should be enough to achieve the desired result.

Thanks!
