Dynamic map region (issue with height lvls)

EDIT: I think the issue with maps not being flat is fixed, so only the clipping issue is left.

So the dynamic map regions are working fine for me if I use height lvl 0.

- But if I use any other height lvl, the floor is not flat and theres some small clipping/pathfinding issues.
- And if I create a map to height lvl 0, but use map parts from different height lvls, it will still have those clipping/pathfinding issues, but the floor is flat like supposed to.

I too have noticed this, sometimes it depends where you originally came from on the world map but this is a problem i have seen too, let me know if you get to the bottom of this

Tile heights are interpolated from the values of the surrounding tiles, this means if you copy a chunk into a region which doesn't have a completely flat "heightmap" the tiles around the edges where the dynamic chunk meets static chunks can become warped. Iirc it can be solved by sending flat/blank dynamic chunks on the outer edges of the filled ones.

But im almost at the center of the dynamic chunk. and not really sure what could I send next to this room as the map should be completely blank.

I tested this and yea it seems it might affect this. - I first teled to the map where all the construction rooms are located, which I know is a flat map, and then teled to my house and the result was better. (but the problem can still be seen)

This is a client bug in 317 iirc.

Dynamic region* and yeah, it doesn't matter, on 317 the heightmap never get's reset, the only way you can change those values to zero is overriding them with an empty dynamic chunk. I took a look back at my code in Fury and if it's not a populated chunk it sends the same chunk as the static one. Now that's based on the assumption that you're using empty regions for instancing, if you're using the "height trick" to instance then none of this will ever work because the height map & pathfinding will always be based on the bottom house.

Yeah im using empty space x is like 10k+.. I was thinking instead of sending new map chunks to reset the height, maybe a client-sided way to reset the heights if dynamic map region is used. (so it should only have the height info for the map that is sent.)

yea should be, since I also tested this by forcing the server load the object & floor data still from height 0 map even though im actually getting the map from height 1 and sending that to client. (so it shouldnt be an issue with servers clipping system)
- u have any idea about how to fix it? (- as I did take a look on #459, and the region loading code did look pretty much the same)

Server side pathfinding

Won't help fix completely cos the minimap flag is still done client-side.

I can't remember the exact line of code but it's fairly easy to fix, it incorrectly copies the clipping data from the destination level rather than the source level iirc. You'd need to make it copy from the source level.

Can you describe the issues with pathfinding? Is the concerned chunk/area of chunks rotated?

Alright, thanks.

Here should be the related code pretty much refactored incase some1 finds it faster than I do:
Client, loadRegion: [Only registered and activated users can see links. Click Here To Register...]
ObjectManager, createRegion: [Only registered and activated users can see links. Click Here To Register...]
ObjectManager (the other methods that are called from client, loadRegion): [Only registered and activated users can see links. Click Here To Register...]

Nope not rotated, its just a bit off or not finding the route, but it finds it just fine if I use maps from height lvl 0. (and the maps are pretty much the same)

I also didnt see the client apply the map rotation to the clipMask and it only seemed to be applied to the overlayOrientation, is that part also unfinished on 317 client? (noticed this while I was wondering how would I easily apply the map rotation to the clipMask value on my server's clipping system, so tried to look how the client does that)

Yeah, I think there might have been a bug with rotating zones too. You could probably look at a newer 4x//5xx client to figure out what the code is supposed to look like - I can't remember exactly what the problem with rotation was.
