Hi all. Still having a problem with this in 4.8 preview. It has always been the same and I haven’t found a fix for it yet.
Basically, importing a tiled terrain from WM always imports it wrong. You can flip it on the Y axis… but that is completely pointless as doing that makes your entire terrain flipped on the Y axis…
Obviously, I could go and flip things in Photoshop or whatever, but that would take forever. For each tile I would need to flip over 10 weightmaps, and on a massive landscape that’s say 40x40km… Yeah, it just wouldn’t be feasible.
I am not saying you are wrong, but I use the Flip-Y and it works for me. Are you setting your z-axis correctly in UE when importing(you need to do a calculation)
Can you show us a picture of your WM outputs? are you using a custom macro, bitmap outputs, or ??
It has nothing to do with the z axis, the z axis is just the vertical scale.
Flipping on the Y axis, does literally that.
Importing after flipping on the Y axis my import it in one piece but the entire map is flipped. The same thing happens if you use a single advanced perlin for generation, or the most advanced network you can imagine.
Here’s the setup im using to test the tiling. I used the layout generator to draw the coord’s on each tile and the border to show it matching up. If I flip on the Y axis, the 1’s are mirrored obviously. As you can see in my previous post.
Hi , the reason for this is that worldmachine and UE4 read the coordinates in different ways.
Try using a node called “Flipper” in your worldmachine file and then re-render with the same Y flip naming options enabled. Warning that flipper does have some problems with some other nodes. Those nodes usually have a little red warning symbol.
The UE4 Output Macro is only doing selections. Selecting slope, height and such, nothing fancy. The three erosion ones are just fed into an equalizer then a clamp and back out again.
I honestly have no idea what’s going on. It looks fine when not using tiled, but completely screwed up when I do.
I did wonder if it had something to do with the blending percentage.
Again, thanks everyone for any help. Its very much appreciated.
I always set Blending percentage to 100%. I also uncheck “calculate edge tiles on…”
The only thing i can suggest is have someone else try to build your WM file and import it. PM me if you want me to try.
No. To be honest the flipped node caused me too much grief as well.
Never told anybody this but the gdc kite demo landscape is flipped compared to what it was initially supposed to be, but I just rolled with it. This isn’t really a ue4 bug its more just an oddity of interface between UE4 and worldmachine. And worldmachines flipper node not working nicely.
It really depends on the terrain. I had another world that I was working on as an alternate backup and for some reason Tiled was causing things to move all over the place (rivers in wrong part of map etc). I seems to happen when doing lots of fancy blending using layout generators.
Overlap settings? Is that the tiled blending percentage?
EDIT: It looks to me that using any form of erosion and tiled building is a recipe for disaster. It just doesn’t work.
If you use erosion and blending when doing a tiled build, the terrain will end up looking nothing like what you expect.
Using blending at all completely changes the elevation of your landscape.
As far as I can tell, the only way to get it looking how you want is to not use any erosion or blending, and not flip it on the Y. Then batch rename the files as you suggested. I can’t see any other way of getting expected results.
