I used the same algorithm to bake displacement maps for two objects. One object seems fine. But another changes its location when i apply displace modifier. I tried different settings of displace modifier, but they give even worse results - if object is not terribly deformed, it changes position in scene. And if it doesn’t change position, it is terribly deformed. Can someone point out in which direction i shall look for problem?
UPD: I found out that i can get appropriate result if i change modifier strength to 0.01 or smt. like that.

But why? It so not obvious. I mean if i want to apply displacement modifier i choose to apply it by UV map, use RGBtoXYZ and need it to fully influence on my LP mesh. Instead i need to do some strange tweaking.
And, anyway, when i have a closer look, my mesh has some bad edges, and crippled surfaces. They are not so visible just because displacement influence is only 0.01. So, the question is still open.
