Alembic model importing "pixelated"?

Hi,
I’m doing some tests with some volumetric captured 3d models.
When I import the model in .FBX or .OBJ, they are perfect, but once I import in .ABC, since I’m using alembic animation (they are a sequence of OBJs).
It is importing with some kind of “pixelated” effect as shown in the picture:

I tried all kinds of export and import options without any success.
Does anyone know what could be happening and how can I solve this issue?

Thank you,
Victor.
