Trouble baking normals from a high poly mesh to low poly mesh using Blender and Substance Painter This is a bit of a mixed question as I'm using both Blender and Substance Painter. I am hoping that someone with a Blender > Substance workflow knows what's causing my frustration.



I am following this tutorial.

Here is my blender file: tracer_redo_final_bake_3.blend

Here is my low poly mesh: tracer_low.fbx

Here is my high poly mesh: tracer_high.fbx



Here are both meshes as they appear in blender for convenience:

High Poly Gun:





Low Poly Gun:





When I try to bake the normal map in Substance, the details come out completely wrong and there are a lot of artifacts. I am aware that some artifacts are normal and I'm not striving for perfection here, but I'm not getting any of the beveled edges or further detail after the bake. The edges that are supposed to look beveled end up sharp and the model gets really splotchy. This doesn't occur in the tutorial video.

Here's a screenshot:





Here are the settings in Substance that I'm using for the bake:





I know that I can bake normals inside of Blender, but I really want to figure out how to do it correctly in substance painter for workflow reasons.

Is there any possibility someone could look at my files and tell me what I'm doing incorrectly? Could this be a blender-specific problem? This is my first attempt at baking and texturing something remotely complex, so I'm kind of overwhelmed.

A huge thanks for any assistance at all!
I figured out that by selecting "Relative to Bounding Box" in Substance fixed the issue for me. I am kind of mystified why this worked, but it did. If anyone knows why this happens it would be a great help.
