Problem with sbsar and material weird render

Hi everyone,
I’ve got this problem ( first picture) when importing a sbsar from substance designer to unreal. The texture isn’t even appearing in a range of colour similar to the one in designer.
I’ve tested importing all textures as targa files and it works perfectly well. However it would be nice to have access to my parameters ^^.
If anyone has a solution it would be great :wink:
Thx
