System Information
Operating system: Windows-10-10.0.22000-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3070 Ti Laptop GPU/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 512.59

Blender Version
Broken: version: 3.2.0, branch: master, commit date: 2022-06-08 10:22, hash: e05e1e3691
Worked: 2.93, 3.0.0, 3.1

Behavior changed in 74228e2cd2

Short description of error
The result of normal texture baking from selected object to active doesn't work as expected. Results are much better baking texture in 2.93.10 version of Blender (same settings). It's being impossible to me to get a usable texture. Here I post a comparison:

Exact steps for others to reproduce the error
1- I attached a file. In the Orange collection is the original model. In the green collection is the low poly model where the texture needs to be baked.
2- Bake the normal texture in Blender 3.2 and then do the same thing without touching anything in Blender 2.93.
3- Compare results.

Test File:

Here are both textures I got:

3.2	3.1

@LautaroIglesias the blend file isn’t attached.

Please upload it. Thank you.

Behavior changed in 74228e2cd2

But this is actually correct, your Max Ray Distance is specified as 0.01 m (which was evaluated as sqrt(0.01)=0.1 prior to 74228e2cd2.
If you raise this to 0.1m it bakes like before (and this is the actual distance we need it seems).

@LautaroIglesias : makes sense?

yes, make sense to increase the current max distance value after 74228e2cd2 (gets expected output when it's changed to 0.1)
Closing this report.
