Hey everyone, how is it going?
I need your help to understand better a issue i’m having, that are these Hard Edges (how i call them, if you have a name for this please feel free to reply) when using some materials in some meshes. Like the image below
You can clearly see there is a division there (highlighted by the black circle) on the mannequins back, dividing the left side from the right side
You can reproduce this exactly same issue by taking the water_material_customMesh from UE4 or UE5 water plugin and attaching it to the default mannequim.
This case is an example of what i want to solve in a reproducible way, because this issue happened with other materials before. I need your help to understand: What are the causes of these hard edges? And how can they be avoided? Is there a way to solve this in this specific case (using the same material)?
Thanks in advance!
I actually figured out why this happens. Accidentally by messing around with another material very similar, when i changed one parameter the hard edge appeared. The parameter i changed was a texture sample node that had “mannequin normals” as the texture value.
So in conclusion: these hard edges will happen when your material doesnt follow the normals of your mesh.
I need a way to make this water material follow the normals of the mesh its applied to, in this case, the mesh is the default mannequin.
Returning here to say that, altought this may happen to some materiais due to normal maps not being mapped correctly to the mesh, this specific issue with this Water material is happening because of the refraction. If you set the value to 1, you solve it.
