Transparency Problem with Model

[anon_46949655]

First of all, thanks and hi to you all.

I’m having a problem with a model I have made.
You can see the model in C4D:

As you see, the model has walls on the inside. The problem is that the walls aren’t appearing on the Unity Engine.

It has an annoying transparent walls on the inside.
I’ve exported the model from C4D as .FBX format.

I can’t understand what is happening.
Need help

Regards.

That is odd. It looks as though the normals are flipped (you can only see them from one side, i’m sure you know).
I don’t use c4d, I use max, but perhaps you could do something similar. In Max, I would make the outside and use the Shell modifier to create the insides. If I got performance like you have I would “Collapse the stack” by right clicking on the object and selecting “Convert to Editable Poly.” This gets max to re-calculate everything as a new object. Is there anything you can do like that?

Otherwise, could you separate the inside walls from the outside and export as two separate objects then re-join them in Unity? That would be an ugly work around…

back face culling off when you export the model or add “cull off” to the shader you’re using to make it double sided

I’m using 2 Boxes with a Boole so the smallest box deletes the current area of the big box.

The boxes are already in polygon edit mode.

I couldn’t find the things you said

Thanks for answering.

I’m sorry but can you tell me how to (back face culling off when you export the model)? I couldn’t find a way.

Thanks in advance.

Try ‘Current State to Object’

@Vimalakirti

Try ‘Current State to Object’

When I do that, C4D generates a new Object, so I have like 2 houses sitting on one another.

Still, I have deleted the old one and the problem still exists :S

I personally only have used Cinema 4D a couple of times, but yes flipping the normals on the inside wall would work.
