Baking Issue and Question

[Wolfer123]

So I have two questions to ask. The first one is when baking and I see the blue for the max frontal distance. Why is it some part of mine aren't getting blue to show they are effecting the bake., I mean the model have both just curious what that means or indicated. Here is screenshot to point out. Just strange how it doesn't have blue 

Also I have to ask, when baking, is this called an artificat in baking or what is this issue. I mean is this occuring because maybe those edge lines aren't so straight on my UV so might need to straight these out as there coudl be stretcing on them.  I have it where these are where the uv seams are for them.  The anti aliasis is up. Just wonder what is this issue that occuring here.

Hi again @Wolfer123,

Thanks for the message.

The blue part of the baking isn't the cage, but the High Poly mesh. Substance 3D Painter has several visualization options to help you with your baking and toggling the visibility of the High Poly is one of them.

The parts that aren't blue are you Low Poly mesh. In fact, the High Poly and the Low Poly should overlap, but because of the difference of definition, some parts are visible and some aren't. This is the expected behaviour and this won't trouble the baking.

Therefore, the max frontal distance doesn't influence the blue parts, it influences the cage.

For the artifacts, do they appear after the baking? From the picture you sent, I would say it either comes from a specific smoothing group or a strong edge without UV seam.

Best regards,

Thanks again for the help. 🙂  Yes they do appear after baking and your right about uv seam. I see the purple line but one thing i find where is how it has it where it stops as shown by this picture here.

Also when you mean specifi smoothing group, do you mean the smoothing group on the high poly or the low poly or at times it can be both. just wondering on that.

I meant the smoothing groups on your Low Poly.

For the purple line, Substance 3D Painter calculates where the edges are too strong and turn them purple. I guess the line you sent as a picture was at the limit for Substance Painter, which causes the line to stop as soon as the mesh was a bit smoother.

These purple lines are only visual aids. You don't have to add a seam where those lines appears, but if there are issues at the baking precisely where there's a strong edge, this is probably the cause.

Best regards,
