    Low resolution decal bake

    posted to: Baking the Normals

    Hi Jonathan,

    Thank you for this great course.


    I encountered my first problem with baking the normals:

    As you can see on the Screenshot my decals are very low resolutionI, I don't know whats causing it - you mentioned that the phillips screw details are too tiny to bake but even the bigger decals are not good looking.

    Can you help me finding a solution?

    And if I want to have the phillips screw details do I have to use the HP model or is there any way to bake it like the rest of the normals?


    Thank you in advance and greetings from Germany

    Merlin

      Hey Merlin, it looks like there's something odd going on but it's hard to diagnose from the image. What resolution is the image you're baking to, and how many samples are you using?

      Hi Jonathan,

      Resolution is 4096x4096 and first bake was at 50 Samples. I already tried to increase the Samples but that just helped slightly.

      Ok, I know I've run into this issue before, but I can't for the life of me remember what the cause was. Could you upload the blend to dropbox, pasteall, or something similar so that I can take a look?

      Uploaded it on Mediafire (.blend + .exr):

      Thank's for your commitment.

      Well I'm stumped. I know for a fact this happened to me before, but I can't find a workaround. In any case it shouldn't be happening, so I'd recommend reporting it as a bug: https://developer.blender.org/ Sorry I couldn't figure this one out!

      Hi again,

      I'm still working on the normal bake but it seems using "Ray Distance" instead of a cage will solve the problem for me.


      I have another question tho, is it correct that I could also bake all objects at once if they are not intersecting each other?

      So Face on Face is ok as long as there is no mesh inside another mesh?


      Thank's in advance!

      Yeah that's totally fine! You can only have one low poly object and one cage, but you can have as many high poly meshes as you'd like.
