As you can clearly see there are no overlapping uv. and the mesh is subdivided to the level where its rigging / animator friendly. I get perfect results in without octane. Its a pain in the butt to even upload an image here. As you wanted how do I share my file to you privately. I dont have anyones ...

Thank you for your help, but it doesnt solve the problem. Why is the displacement map ripping the model?

I am running into the same problem, I sculpted in c4d and once I bake displacement, normals and ao, it blows up the model when I render it using octane. Works fine in c4d native render. Please help
