Model transparent after export

[Sharknado]

I made a model on blender using the mirror modifier then I applied it but when I export it to another format the model has half of the other side cut off or some of the parts just have holes

Can you post some pics?

Have you checked your face normals are all facing outward?
If some parts of your mesh have a darker slightly blueish look to them then their normals are the wrong way round. In Blender both sides of a face are drawn by default, in game engines and some other software the back faces are culled by default.

It could be something else so a pic or two would be handy, thanks.

Here is how it looks like in a game engine: https://gyazo.com/9b77a9d8acdc897b51ef794b75dacef2

I also seem to have some problems with the uv map since when I set it to render the eyes look different:

You posted the same image twice. Also I'm sure you didn't mark seams for uv unwrapping which could explain why the texture looks odd.

My bad
here it is: https://gyazo.com/686a6c5819e6c8673fa9e9220663b8da
it was the normals thing I just fixed it only the uv map is wrong atm.

And how do I mark seams for uv?
Also Do I unwrap or export it as a uv/png? then edit it in a different software?
Since I mostly did it on edit mode by selecting all faces then just putting the textures

[tripmix]

While in edit mode CTRL + E mark seam then UV unwrap.

This is for example purposes

Imagine your model has to come apart but then come back together.

You can then unwrap (after seams are marked) then export the UV layout open it up in photoshop or gimp and do the texture work there.

Also quick note, no overlapping UV's you may find it easier to use 2 UV maps for the model.

I edit the uv map it still keeps giving me the wrong results.

I make player-models in Garry's Mod and I am having about the same issue as you are having right now. However.
This only happens if I use the duplicate tool to save time. The part that I copied from looks normal but the duplicated meshes look hollow like on your picture.
Presumably, something gets screwed up in that process.
Did you use the duplicator tool by chance?

@Mailer
No I don't think so I only used a mirror modifier
I did learn how to fix this tho by going to edit mode and doing CTRL +N

@Dusk

I'll try doing the same.

@Dusk

Holy crap, it worked!
Thank you so much, and whoever you got that tip-bit from.

I dont know about you, but Ctrl+N is making new session to me. However if I use SHIFT+N it's actually works.

That thread is 6 years old. Things have changed.

Either way - no one seems to have mentioned that you need to tick APPLY MODIFIERS when exporting.
