NM baking issue

bosko

Hey Community ,

Its my first time in a forum and I hope I don't break any rules by just opening a new topic. If so please let me know for the future.
In a nutshell:

I am quite new to the 3D modeling world but I keep learning. For a group project (a game) I have to make some models. I made them partly in Blender and partly in 3DS Max which caused some problems during the making but I guess I fixed those issues. 

I've made a Low and a high poly of my models (here: banana canon ) to bake a normal map. I put them on top of each other and retopologized the low P.

I saw an older post about how to export and import from Max to SP here in the forum so i exportet an triangulated fox file, with smoothing groups checked (all on 1) and Bi-normals unchecked for the Lowpoly.

Below you can see my import settings for the Lowpoly within SP:


then it looks like this:


here are my nm baking settings:


in Max my models are splitter in different parts using the suffixes mentioned in the settings above so I decided to choose the options above.

And finally here is what i get out of it:


I guess you guys all can see what's wrong ^^... wheels are edgy, bottom part of the barrel looks wavy, ...and so on...

I didn't put any details in the highpoly its just a lot smoother. I wanted to add some scratches in SP here and there but nothing too crazy. Moreover I need to say that i am a beginner in all these tools. 

I am just wondering whether it is my unwrap, my highpoly, my export/ import settings or maybe my lowpoly just isn't round enough..

Well that was a massive nutshell... BUT any help would be greatly appreciated!!! Thank you for reading!

Yes, your lowpoly is not round enough, you can read about here, go to the ''Best Results'' tab.

Alright thanks for your reply:D i‘ll try to fix that and see how it works. Thanks for the link as well! You know whether my settings were okay? And of a triangulated poly would make Any problems when animating it?

Udjani

The settings are fine, i have 0 knowledge about animation but i know that they are made inside a 3d app, so make sure to always have the original meshes saved without triangulation just in case.

okay, cool. Thanks again!

I like to set the rear projection to a higher number usually but the bake looks like its technically good so you can leave it. 

There are some sticky threads in technical talk about normal maps that are well worth reading as well the tutorial linked above.

Triangles aren't a problem for animation but you do need to make sure that the mesh has enough density to deform if it needs to. You'll need to ask the animator what the mesh needs to do

Alright, good to know. Thanks a lot guys!

hey guys, just wanted to let you know: I just went back into my low poly and added a couple more subdivisions here and there. I used pretty much the same settings as mentioned above and the result is muuuuuuuch better!

Thanks again guys!
