[WIP][1.9.x-1.12.x] Scatterer-atmospheric scattering (0.0838 - 14/08/2022) Scattering improvements, in-game atmo generation and multi-sun support

[blackrack]

What are the reasons for the standard KSP-Unity lighting system not being capable of doing this? I made a crude attempt to see what had prevented Squad from doing it, but I don't know enough about shaders or Unity rendering setups to parse what I'm seeing. I used a simple sphere, scaled and positioned, with shadows enabled for the ScaledSpace bodies and light:

What is even going on in those orbit views?

Mockup of shadows being cast by other planets onto each other, Now that would be freaking cool!

Performance mostly... Dynamic shadows are expensive. I tried doing it with the existing bodies similar to what you tried, but you get the issues you've seen. I'll be using a projector along with the scaled space body shader to render the body shadows.

When I used think of shadows being created in games I would almost imagine a cone of "shadow" that would create shadow on anything that enters it. That's how it is in real life but I'm pretty certain that it isn't even vaguely similar to that when in programming.

Hello Scatterer community!

I've got a little problem with my setting file (config/Settings.txt), when i leave the game normaly (by the menu) the setting file is erase by other settings. I've got two ways for this,either I make a back up, or I leave the game by Alt+F4.

Does anyone else have this problem?

What does erased by other settings mean? The default settings? Are all the config points erased? Also, you could just set the settings file to read-only and that should solve it.

It wasn't exactly the default settings, just the 2 first default config points and the rest of my settings erased. I've tried to set the settings file to read-only but it make the atmosphere in all the solar system when you are on your ship, not on ksc. Try, you will see!

But now, I don't know why I can't reproduce this issue, so much the better!

Sorry for the inconvenience.

Basically, a depth map/texture is rendered based from the camera view. This is then projected onto the scene's shadow receivers. This is also why some weirdness occurs at the edge of the two camera planes.

A good wiki article on the matter: https://en.wikipedia.org/wiki/Shadow_mapping

I'm not entirely sure. It doesn't seem to be an inverse shadow or a plane through the body because it's got those weird square bits at one side. It changed position, size and whether the rest of the planet was filled black based on camera position. You can see the effect on the Mun only when you're very close to its surface.

The testing in this case was done by iterating through all lights and setting their shadows to soft, setting castShadows and receiveShadows to true for all renderers with Mun or Kerbin in their name, setting shadowDistance to a stupidly high value, then setting a primative sphere's scale and position to that of the Mun CelestialBody.

Red Sun fix?

[Flef]

Is this a completely new bug with the new version or has it been happening for a while?

Does it work if you turn pixel light count back to 8?

It happened to me too. It occurs when I alt-tab to the desktop mainly. Sometimes also when I switch between the orbital view and the rocket while on Launchpad. It was occurring yet during the previous version of scatterer.

[jwenting]

had KSP being severely crashy for a while now. Thought it was running out of memory, but removing mods didn't help.

Finally I found the one (almost) constant in most of the crashes:

(Filename: C:/buildslave/unity/build/artifacts/StandalonePlayerGenerated/UnityEngineDebug.cpp Line: 56)

NullReferenceException: Object reference not set to an instance of an object

at scatterer.SkyNode.OnDestroy () [0x00000] in <filename unknown>:0

at scatterer.Manager.OnDestroy () [0x00000] in <filename unknown>:0

at scatterer.Core.OnDestroy () [0x00000] in <filename unknown>:0

(Filename: Line: -1)

Hope that helps you

It's pretty normal to see that when the program is shutting down, for any reason.

All of the components in the game are cleanly destructed first and it notifies them that they are about to be destroyed in the event that they might want/need to take action. (such as freeing resources that they were using)

In otherwords, that error happened BECAUSE of the crash. It did not cause it.

Works fine in DX9 for me.

What do I need to edit in order to fix the sizing to work with my KScale2 setup? I assume this is accessible, since the RSS scaling exists?

It works right out of the box. The only thing thats not working as intended is map view. Blackrack said he was going to take a look at that.

Edit: Actually there's slight z-fighting/flickering in PQS with KScale2. And there's worse PQS z-fighting with 10xKerbol so:

blackrack: Any idea how to fix z-fighting with larger scale solar systems? (using dx9 btw)

Post some screens please, I never heard of z-fighting in PQS.

Only config tool requires dx11

I assume this refers to the issue where there is a smaller Kerbin apparently inside Kerbin?

[ThorBeorn]

Post some screens please, I never heard of z-fighting in PQS.

Then it's probably not z-fighting. There's small black dots which flickers and appear more obvious the farther away you look towards the horizon. It was hardly noticible in the 2x rescale until you reached 12km. In the 10x rescale it was obvious from the ground almost. I'll see if I can get a screenshot.

Yes exactly. It's also mentioned in the OP.

Hello, and thanks for a terrific mod.

Is there a way to get around this bug while keep using DX11? I really want to play with scatterer, but cannot go opengl/DX9. Any other alternative?

[HafCoJoe]

First off, I love your signature. Do you know what show it's from originally?

Secondly, I am sadly not sure what can be done about running in compatibility modes. The current scattering effects in KSP are limited from what I understand. Wait and hope!

Its from Macross 7 if I remember correctly. Here is a better res picture of it, click on the thumb..C:

Well... What is the reason you must stay away from DX9? Mod capacity? There are ways of squeezing 50+ mods in and still not use DX11 or Opengl. Are you a windows user Linux mac?

If you're going to spread that last link around you better let people know in advance that mod makers who have locked out 64bit will not be happy about bypassing their prevention mechanisms and will not give them support.

Good point. I thought it was on the unfixer page. But absolutely, there is a reason mod makers don't support 64 bit and that's because milage drastically varries from user to user. The setup of your equipment has a lot to do with it as well. So yes I hearby submit myself for a scorning as it is well deserved But thank you for throwing that out there so I don't go making more of a mess for all the modders.

DX9 is only available on Windows - Linux and OSX only support OpenGL.
