Checked ckan today and got some updates.  Mostly Scatterer and I think one EVE.  The update went normally and KSP runs ok.  The thing is that now the dark side of Kerbin is white.  Just wondering if this is a holidays theme.

I thought this too initially, but then it didn't make sense because the day side isn't covered with snow.

btw, as a JNSQ_10x + GPP_10x + GPP_secondary user I do NOT have this issue.

Yeah, I was trying to be tongue-in-cheek.   I just have basic mods like Scatterer, EVE, and Waterfall.

There is currently a bug with the shader where the log spams missing "_MainTex" whenever Jool is loaded. I have tracked it down to the latest update. To replicate just zoom into jool on the Tracking Station.

Aaand fixed

 

[Alioth81]

I am Running the latest scatterer build based on some AVP configs and distant objects.
I just noticed something I never actively saw before. Maybe it was always there but I only notice it now because the atmosphere seems to be larger or it is something that changed. Eve seems to be drawn on top of the atmosphere instead of behind it.

Is this caused by distant objects or scatterer? Can I do something about it?

[mindseyemodels]

for some reason the oceans and atmosphere shaders stopped working... are any mods incompatible with scatterer? because i can't play ksp without scatterer now without thinking "wow, this looks like hot GARBAGE"

@blackrack, it says on the Wiki that:

Generating precomputed atmospheric scattering tables

Since version 0.0824 you can just generate the atmosphere directly in-game, from the atmosphere tab in the UI.

Previous versions need to use the config tool to export atmosphere files.

... however, I presume that if you're implementing a Scatterer atmosphere on a new body, you still have to go through the process of generating the textures with the Proland tool, then prepopulating configs for the body to allow for the in-game GUI to then pick up a 'base' atmosphere for it to then adjust? Also, with the Proland tool textures now not being handled as they were previously, now being held in the ScattererAtmosphereCache folder, how do we distribute the custom textures for bodies?

Hmm I detailed this in the changelog but didn't in the config tool section. So basically you don't need to pregenerate a texture or distribute any of the atmosphere cache files and you can completely forget about the proland tool.

For a new atmo you just create/ship the atmosphere .cfg and the .half is generated when needed on the end user's machine directly and reused from there. A unique .half is generated from the atmosphere params and indexed with a hash, so even if you rename a planet or modify the atmo .cfg externally it will always generate or use the right file.

Check out the .zip file scatterer comes in, there are no .half files included.

I thought as much. That's handy for distribution.

I guess that the easiest way to create new Scatterer atmospheres for bodies is to copy a default, rename the body identifier and then edit in game(?)

Pretty much, I copy kerbin's atmo then go ham

I've noticed that when in the in-game GUI in the Atmosphere tab, when I change the 'Thicken' values and click 'Go', it adjusts the Rayleigh and Mie scattering RGB values respectively. Is this button just a multiplier box to make adjusting those values easier if you want to increase or decrease all the RGB values together?

Yep, and there is a rescale button which increases the height scales but decreases the colors accordingly to rescale while keeping the same overall thickness.

[Poodmund]

I see. Whats the best way to reduce the opacity of the Scatterer atmosphere whilst retaining the brightness of the body below? I think I ran into this issue last time wherein as you tried to reduce the effect, for a very thin atmosphere, it would artificially darken the body a lot.

Got any screenshots of the body you're working on and your settings?

Just use thicken with a value below 1 until you're happy. But remember that a very thin atmo can't have nice sunset colors.

For stock planets like Kerbin and Laythe I found that the base scaled textures don't have enough brightness or contrast to look good out of the box even with a thinner atmo, I added some controls to fix that ingame, don't remember what I called them but you'll find them in the last big changelog.

It was Thatmo in OPM which has a gnat's fart of an atmosphere. I'll post something later when I get access.

Anybody has issues with custom Sunflares ?  Trying to use the Sunflares of Maar  but somehow I do not see it in the game at all.   And when I click alt+F10  to check in game via Scatterer the sunflare settings there is nothing to edit...

Ok I am using AVP , I checked it from top to bottom and there is no config that is messing with sunflares.   Moved to check the Sunflares of Maar config and I think, could there be missing the file name like Sunflare.png or someting like this in the config ?     Or maybe, I read in the Sunflares of Maar topic that somebody had problems with Scatterer and B9PartSwitch, but as far as I know this was fixed already.

I think you should probably get rid of that configPoint, the values are mismatched and all over the place for scattering and extinction, and they garble what you can do with the generation. Just copy the configPoint of stock Kerbin as it's neutral, your atmo will suddenly look thicker, then use the thicken modifier in atmo tab to make it thinner until you're happy, that should get you what you want.

I'd recommend no longer modifying the configpoint settings now but keeping them at the neutral/default settings, as these are not physically correct and will get janky results, only use when absolutely necessary

@blackrack   Sry , next time I will do a spoiler.

Anyway I fixed it.  It was missing the  "!syntaxVersion = 2"   at the start of config and not it is working.

Thank you for you hard work man. I really love Scatterer  

[apotawafi]

I have installed scatter with its default config and sunflare from ckan but it seams to not be working these are the only visual mods got a bunch more installed but i don't know if they are conflicting 

[Big Katz]

Any word on a fix for jool/lindor for JNSQ? I know that a previous release of scatterer works but then you lose some other features. Don't know if its a scatterer problem or JNSQ problem.  Thankyou for this great mod regardless.

It’s a JNSQ problem - the configs aren’t updated for the new scatterer version, though someone has in either this thread or the JNSQ one posted basic configurations that are.

how do I change the color of the kerbin?

[blackrack]

Just pushed a small update restoring compatibility with 1.9.x 1.10.x 1.11.x, alongside 1.12.x, as well as compatibility with systems not supporting 3D textures (mostly old integrated graphics).
