Hello, we use Unity to upload multiple 3D models of apartments. Some of them are mirrored, see for example “PND model D0313” and “PND model D0313 mirrored” (search for them, this Forum is not allowing me to put links ).
The mirrored model is the same as the original, but with scale
x = -1
In Unity this works fine, but as you can see in the link above, in Sketchfab all our mirrored models are inside-out. A possible solution for this is to set all materials as double sided, but currently we can only edit them one at a time, and we have many models each containing many materials, and that would take an absurd amount of time.
Is there a better way to have mirrored models in Sketchfab?
If not, is there a way to edit all materials at once, so we could set all materials to double-sided?
