Unpacked alembic unmatched bump/displacement strength

When importing an alembic from maya, it get scaled by 0.01. When we unpack it down the line, the scale of the bump maps seem to become stronger by a factor of 100. How do I prevent this from happening? Thanks.

Houdini and maya has different scale, the maya geo imported to houdini might needs to scale down 0.01, so if your shader was made in maya, when you exported your geo and shader into the houdini, your geo scaled down to 0.01, your material unit needs to scale down 0.01 as well. those unit will affect your normal, sss and displacement. you need to scale down 0.01 of from your old value for those setting.
