Model changes after uploading to roblox studio

[mepsolo (Turbinator)]

So, I create a model in blender, save it to “Wavefront (obj.) legasy” file and upload it to Roblox studio “Import 3D”. The model breaks, disappears in places, sticks together, the condition worsens. how can i solve this problem?

When applying the texture, the problem becomes less noticeable, but still looks bad

have you tried importing via asset manager? (view > asset manager > import button)

Try exporting it in a format wavefront (obj. )
(Not in wavefront obj legasy)
I don’t know exactly the difference between the two, but

But when the model disappears in places, you may have some poligons turned the other way around in the blender. blender renders them from both sides but roblox does not. (if you don’t set to mesh DoubleSided)

The result is still bad, but already a little better, (changed the model in size, and made it bigger, but in my opinion it did not change anything)

I converted the model to “FBX” file, it became much larger in size, but it looked good
