Sky

[scrawl]

Regarding the dependency, is it small enough that we can build it into our project? Or am I completely misunderstanding?

It's an Ogre plugin (like GL RenderSystem), so we are not building it.

1. a backend that calculates color modulation for atmosphere and clouds, as well as the fog colour

#1: I am pretty sure that there is nothing in the world model that can be used to determine these. I guess these depend on the weather and as such I am not sure if we should call it a backend task.

I confirm that at least the fog color is set in the morrowind.ini... I am sure because I wrote a mod for that.

Right. I did not consider the Morrowind.ini file (only the ESX files). Well, as I said before, best use a fixed hardcoded value for now.

[scrawl]

this is roughly the class design i have in mind, do you agree?

==> : owns
--> : knows

World ==> WeatherManager
WeatherManager --> RenderingManager

RenderingManager ==> SkyManager
RenderingManager ==> WeatherEffectsManager [ for rain, ashstorms, etc ]

[Zini]

Looks reasonable to me.

If you have to decide a fixed value I suggest to use the fog colors I linked. The values make the fog of about the same color of sky giving an Aerial perspective aspect to the game.

Of course if you meant a single fog color for all weather condition... nevermind go gray.

I am getting a link error when trying to build your branch:

Forgot to add a file?

[scrawl]

yes sorry, fixed

[Zini]

Lovely.

I forgot thunderstorms on the ToDo list. I need to find out which textures are used for them.

these might be related (but they look like flash effects, and not the actual lightning):
./textures/tx_stormalpha02.dds
./textures/tx_stormalpha01.dds
./textures/tx_stormalpha00.dds

and then these ( i'm sure that not all of them are relevant, there also must be some that are used for the magic lightning effect)
./textures/vfx_lightningrod04.dds
./textures/vfx_lightning_shield.dds
./textures/vfx_lightningrod.dds
./textures/vfx_lightningspark.dds
./textures/vfx_lightningbolt.dds
./textures/vfx_lightningrod05.dds
./textures/vfx_lightningrod02.dds
./textures/vfx_lightningrod03.dds

If someone has a picture of thunderstorms in morrowind flying around, that'd be helpful, because you must be lucky to get a thunderstorm weather (and even more lucky to press screenshot at the correct time to catch a lightning)
