Hello folks, i’m facing a problem while making a project for my university. I hope you can help me solve it. I’ve made a building in 3dsmax and have imported it in unity3d. Problem is that inside unity the model is 1 sided. Meaning if you looking from inside then all walls are invisible. In max we solve this by simply turning on 2sided option on the texture we give it. Can you please tell me how to fix this inside unity3d?
thank you
You could create and use a two-sided shader. But, if you want correct lighting, you may need to duplicate and flip the geometry. (Ideally, a model of a building should probably be built so as not to have individual surfaces that are visible from both sides, at least aside from special effects such as windows and so on.)
can u link me a tutorial on shading in unity?
and duplicating+ flipping the polygons of the walls… i should do this in 3dsmax before exporting?
http://unity3d.com/support/documentation/Manual/ShaderTut1.html is a good start. You’re interested in “Cull Off”, or just search for “unity 2-sided shader” in google.
Yes, Duplicating polygons has to be done in 3dsMax.
