How to fix Error converting texture on specular and roughness?

[Anonymous]

When I add my roughness and my specular maps and start a render, this message appears in the console: 00:00:04 642MB ERROR | [htoa.texture] Error converting texture[6]: C:/Users/alcastonguay/Desktop/Texture_ground/megascan/Rock_Cliff/olqiJ_2K_Specular.jpg

How can I fix this?

Thanks.

It's just that one texture?

No, it happens to all of my textures that are connected to my specular or my roughness. Just to be clear, I have many shaders which have their own textures for spec and roughness.

Data compression failed.

That's a known issue. For now, you'll have to use the Tx Manager
