Hey there!  
Does anyone know why I have these Gaps between my level streaming proxys??  
Landscape was made in GAEA and imported as an heightmap.  
Thank you

Hey there @_iva! Welcome back to the community! Do any of the proxies have imprecise relative transforms? Either + or - less than 1% usually when I’ve seen it can cause this.

A couple of threads about this issue:

> Hi all - I’ve noticed on a heightmap-generated landscape that it is generating gaps between landscape components. I hadn’t noticed this in 5.0 EA but it is happening now in 5.0.2. Images attached below. Any ideas on how to resolve? (note that this is not just an in-editor visual problem; these do appear to be gaps and not just grid lines, and they are visible also in the packaged project).

> Here is the solution (had the same issue, solution is tested and confirmed): The displacement is relative to the horizontal vertex spacing and due to the compression in the HFZ file format, which allows a small height encoding error (+/- 1% of the horizontal scaling). Do this in L3DT: go to the ‘File-\>Format preferences’ option in the L3DT menu, select the ‘Project maps-\>Heightfield-\>HFF (L3DT)’ tree option, Press the ‘options’ button, and set ‘DataSize’ to 4 and ‘FloatFlag’ to true (double…

Thanks for your answer!  
Because of GAEA you have to use some math to get the right scale.  
For example (a 5km x x5km) landscape:

For X and Y scale: 5000\*100/1009 (1009 is the heightmap resolution)  
I adjusted the scale to be a TINY bit bigger, and now the gaps are gone.  
I dont know if its the correct way.

As long as it works without any major side effects, I’ll call it a win! It seems that other users in that previous thread did the same. If there are any major complications, please let me know!
