How to fix transparent faces of meshes when importing?

Hello everyone! So i want to make my ugc, but when i import my mesh into studio it has some transparent faces which is of course bad

I could use double sided (maybe), but as you can see in picture i have fire which is should be like that, so if i will use double sided it will get ruined

Any ideas how to fix that?

It should look like that with textures:

In Blender, you can switch on Backface Culling to see how the Mesh’s Normals would look, this also lets you see how it would look if it were to be ported into Roblox

In edit mode, the “Flip”, “Recalculate Outside”, and “Recalculate Inside” buttons should help you out here, select the affected faces and fiddle around with one of those buttons

(idk too much about blender so I’m hoping this helps!)

i tried flip thing on meshes that are inverted, it didnt help

Nevermind, i fixed that =D
Flip didnt help me for some reason, but recalculate outside did! =) (maybe, i was tired back then and imported old glitched mesh when i tried to fix that)
