Backface settings

Since getting the iPhone 12 Pro I’ve been doing some 3D scanning of rooms. For these to be useful, you really have to set backface display to ‘cull’ so that you can see into the room from a camera position outside of the space.

Currently, I believe the only way to do this is as a global setting by display mode.

I don’t want to have to change this setting every time I work with a 3D scan and then back again when reverting to normal 3D work.

Ideally, I would like to be able to set this by object. At the very least, I’d like to be able to set it by model file so I don’t have to keep changing the settings as I work between different files.

I think you can achieve your goal by using a double sided material and setting the back faces to a transparent material.

Edit: Forgot to mention that for this to work, you have to set the backface display to “Rendering Material”

In the image above, the object on the left is set up this way. The object on right set to default material.

Thanks, that’s helpful. It would still be easier to have a file or object setting so that it can be toggled easily. But this will be useful I think.

Hello - if you set up a special display mode for this, you can assign it via SetObjectDisplayMode.

Thanks, I did it via the settings panel but achieved the same end result.

I guess between material settings and custom display modes, I can pretty much achieve what I want.
