Have a look at minute 5:00, there you can see if your normals are faced inwards.

You can also show me your model if you like

[woeful parcel]

is screenshot enough? or would you like the .blend file?

it's fine with me either way

[cold hearth]

as you like, i can have a look at the blend file

[woeful parcel]

here. thanks. I'll take a look at the video in the meantime

[cold hearth]

Ah, you just have curves there

[woeful parcel]

I created the model from a .svg file. Extruded it by 0.0001 and added Solidify to thicken the walls by 0.0001 too

[cold hearth]

Select your model and then do this:

ah sorry, not curve 😄

"Mesh"

Object > Convert > Mesh

[woeful parcel]

ok, thank you 🙂 I've converted it to a mesh, imported it to unity. No errors about normals anymore, however, the light issue is the same

[cold hearth]

[woeful parcel]

ah, sorry, I did get the error about Normals in Unity

[cold hearth]

check this one out. Should not have any problem

[woeful parcel]

haha, you're absolutely right! 🙂

now, what did you do? 🙂

[cold hearth]

Thats your model. You have no smoothing groups.

watch in my Tutorial at Minute 6:00

there you can see how to fix.
You need to define sharp edges. (like everything about 90°)

And your Scaling is off... this is in Minute 2:50 in the video.

[woeful parcel]

ok, got it. No more lighting issues. Two questions, please. I exported it like this, but I get this scaling after importing to Unity, which multiplies the actual scaling in Unity by 1000. How can I get 1m to 1m?

[cold hearth]

Do you use the standard FBX exporter or the exporter i mentioned in the video?

[woeful parcel]

standard

[cold hearth]

try to set a check in apply transform

[woeful parcel]

i did in the second screenshot

[cold hearth]

ah

yeah you are right its 1000 scale. one second

[woeful parcel]

your model you sent me is fine

maybe I should use the plugin from the video?

[cold hearth]

Did you do the "apply all" step?

if you select your model and press "N" you should see its transforms

if its like this, its fine

if you have weird rotations or scale, you have to apply them with CTRL+A

[woeful parcel]

scale is 1000 on my model. ok. let me try that

[cold hearth]

Then you do Ctrl + A > Scale

[woeful parcel]

ok, got it. my final question is how did you smooth out the walls, please? I made all edges as sharp, but it seems I missed something?

[cold hearth]

i already explained it to yourself

you made all edges sharp

If you use the auto smooth, you can define an angle above everything gets a sharp edge

if you want to do it fast

I cannot find Normals->Auto Smooth

however, I was able to smooth out edges in Edit Mode by using this:

[cold hearth]

thats weird

Which Blender Version are you using?

[woeful parcel]

4.1

[cold hearth]

Hmm.. maybe they moved it.. im on 3.6 ^^

do you have this one in object mode?

[woeful parcel]

I have this, but all three Shade buttons do nothing

[cold hearth]

Not sure if you overwrite it with your edge settings

https://blenderartists.org/t/blender-4-1-auto-smooth-is-now-a-modifier-only/1488922

these bastards moved it to be a modifier 😄

[woeful parcel]

never mind, you already helped me really a lot! and the issue I had is fixed 🙂 It's now just a difference in blender versions

ah, ok 🙂 I'll try that

looking smooth now 🙂

thanks, again!

[cold hearth]

keep in mind that edges like 90° must be sharp
