Hello friends !
I have a problem when I put an equirectangular texture to the world. It almost works, but there is ugly deformations when playing game. Is there something i’m missing ?
In viewport, everything is OK :
When I run the game, it’s not as nice :
I made another try with an image from wikipedia, same result :
original image :
Thanks in advance for helping me,

Hi, that is a “known” issue, reported here: https://github.com/armory3d/armory/issues/1277.
Thanks,
I solved the problem by putting the earth at the “pole” of the map, where there is no deformation.
I know there are deformations on the stars but that’s invisible 
That’s quite an interesting solution 
, I was looking at the code to see if I could maybe poke it a bit to see if I could fix it, and I found that the environment shader code resides here: https://github.com/armory3d/armory/tree/master/Shaders/world_pass, in the fragment shader in a particular line there is call to a envMapEquirect function,
https://github.com/armory3d/armory/blob/dfda5f9dbbb2dd07228c755edce9fd98bace41a9/Shaders/world_pass/world_pass.frag.glsl#L138 that is a function that resides in here https://github.com/armory3d/armory/blob/master/Shaders/std/math.glsl.
Googling “environment Map Equirect” and directly “envMapEquirect” too I found different snippets of code so I tested the first one I came across https://github.com/vorg/pragmatic-pbr/blob/master/local_modules/glsl-envmap-equirect/index.glsl, and changing the one in armory to be like that one it seems to work, only that the orientation and rotation is wrong… with a bit more of shader and math knowledge than I currently have I think it could be sorted out 
.
The problem is not in shader, rather in hdr generate by cmft
See the comparison (ignore the quality):
(Left is original, right is generate by cmft)
Binary of cmft build is 2 year old, I think they should be update, this might fix the issue or the issue might resides in the export settings of cmft
