Help! Normal map problem.

[Erik Salaun]

Hello,

Im working on my FPS rifle now for a while but i cant fix my problem with the normal map baking, When I bake the round part of my gun it keeps baking lines where the mesh is even tough i set it on smoth shading. I dont know how to fix that.

Hey Erik, I haven’t been able to replicate this issue. Could I take a look at your file?

Sure. Here is it: http://pasteall.org/blend/index.php?id=50157

And heres the map: http://pasteall.org/pic/8912c59626458ec791fe99f8f133c029

I have my problem in the barrels group with the barrelsup object. I also had problems with the barrelslow1 object which I already baked. I dont know if I did it right because I had to change the cage object in Edit mode in order to get the detail in the corners. Maybe you could take a quick look if I did it right?

Thank you very much!

Hello again!

I have found the solution by playing around for a while now. Turns out that the problem was that i subdivided the cage & the low poly objects. Im not sure why, but when i dont subdivide them the map looks fine. 

Thanks for your help anyway!

Aha, good catch! Subdivision can be helpful to prevent skewed details (if that’s a problem), but smooth parts of objects like this should not be creased when subdivided (or using Simple subdivision, which does the same thing). 

Good luck with the rest of the project!
