Describe the bug
I’m trying to go through the seasons to see how the mod works visually, but nothing really changes. Using the setTerm command and setting its value to summer doesn’t make the snow melt—neither on the client side nor the actual snow blocks.

Platform(please complete the following information):

• Minecraft Verison 1.20.1
• Forge 47.4.8
• Mod Version pre13-3-1

You only changed the season, but not the snowing state.
You can use this command:
/ecliptic weather xx snow_depth 0

I had a survival game session the other day. It was the Insects Awakening solar term, but the snow was not melting at all.
For testing, I set up a new world in creative mode and used the Hourglass mod to speed up world time, but again there was no result. I do not understand the snow mechanics.

I'm sure I'm not supposed to change it manually with commands.

I'm using the Legendary Survival Overhaul mod as well, and the temperature there works correctly. The temperature changes depending on the season/solar term, but the snow is still not melting.

I’m not entirely sure whether the Hourglass can accelerate snow melting. However, in Insects Awakening, even though it’s already spring, some biomes may still maintain snow that doesn’t melt. I noticed you have birch trees, which likely belong to a cooler biome. If you have DynamicSnowTerm enabled, and the year happens to be colder, the snow will persist even longer.

Each biome has its own snowfall schedule, assuming the modpack author hasn’t imposed any restrictions. The snowfall timing can continuously transition from no snow to snow even during summer.

Here is a deprecated table for your reference. It doesn’t fully match the latest version, though in practice the differences are minor. It’s provided merely to help you understand the snowfall mechanics.

So, for example, in the winter biomes, which spawn with snow layers by default, it will not melt or change with the seasons, right? Does Ecliptic Seasons only affects client-side snow rendering at this point?

Here are some additional tests:

Snowy island temperature:

Neighbouring island temperature without snowy layers:

The snowy island shows a higher temperature value, but it is covered in snow, unlike the other one.

Why are you using LSO’s thermometer to look at our system? They’re not actually the same thing.
LSO’s thermometer is actually heavily affected by local factors, whereas ours is based on biomes.

The snow is distributed by the server, and it can affect some related mods. I’m not sure whether LSO is one of them.

For ours, you need to enable the client->debug option.
At the same time, you can use a command to obtain our hidden thermometer.

Under the ecliptic command, there are also some commands for exporting biome distribution maps.

I suggest you continue asking about this in LSO’s repository, or move the question to another issue.

Of course, in most cases, snow is just an additional rendering effect, and this is also to make it easier for it to update with chunks.
It’s possible to detect whether it exists, but the author of mods must call our function interface to do so.

And snow has a snowfall schedule, which differs depending on the temperature biome. It would melt when time coming.

Thank you. I'll test further. Let's close the issue for now.
