Hello,
I'm looking for help with proper season handling.
I've figured out that POL sends a packet 0xBC to logged character to make client show requested season. The issue is I cannot really find how and where graphic changes are managed. As far as I know tree leaves are changed by tiledata.mul with foliage flag, but there also some other statics/art changes that I can't make to behave the way I'd like to. For instance 0xC9E changes to 0xD3F at fall only, and I would like to know how it's done. Could anyone be so kind and give me a piece of advice?

I suspect this is hard coded within the client but maybe someone knows better.

I am also interested on this.
On our shard, the snow tiles are very ugly and and it would be nice to find a way to fix them.

Sadly, I have no useful info to add to this thread.

Yes. The snow tiles are a real issue. You can RP only so much but when the "world" is ugly or the graphics are a patchwork of oddly placed tiles it does get in the way of enjoying the game.

Yes, everything is hardcoded. On our shard we've made custom art.mul for winter, with all winter graphics. If it's winter on server, client uses modified art.mul.

I understand it is hardcoded, but do you have more details? If I open the files with UO Fiddler, I can't find the winter tiles.

Where are they?

Edit textures, write on them their ids, and you'll find out.
To find season changable tiles it's better to use Centrad, draw a map with all items you are interested in and change seasons (0-4). If they don't change you can replace initial tileart id with winter graphics.

Here is an example of textures for winter and summer - http://imgur.com/899gEaM

There is a table directly in client which tells what to change based on the season information it get when receiving the packet from server.
I looked into this a long time ago, and without a good knowledge how to edit the client.exe itself on assembly level using a dissambeler I say either make a custom map/statics mul for winter ( this is the way OSI handles it on their servers nowadays aswell, just requires you to send it to all players every winter ) or leave it be.
