A Mesh I am using stays Transparent, can’t change it.

[wrongwright]

So I just added Mesh>Circle to use as a handle but. it has taken on the properties of the walls?  I am in Blender 4.0.2 and so my setting not the same as in video.  I looked Object Properties, no camera setting there.  I looked under Camera, no Object checkbox there.  Not sure why it acting this way.  The window making was no problem.  The bed no problem until I try adding this shape.  FYI…I used Solidify and that took care of me.  But why would this have been the case.  Is it because of Circle?  Or was it a bug?  Mostly user error?  :). haha

Hi @wrongwright ,

If you Add a Mesh Circle (or any other Primitive), it comes in with default Values (in the case of a Circle: 32 Vertices, a Radius of 1m and no Faces).

If you change (one or more of) these values, in the Adjust Last Operations Panel (or F9), Blender will remember that and the next time you Add that Primitive, it will use those changed values. (Until you close the .blend file.)

Blender 4.0 is really not that different from the Version used in this course, as far as the modeling you do here is concerned.

I really cannot understand the rest of your question (from “I looked Object Properties…” onward), sorry.

(Not completely sure, but I cannot imagine you’ll find a bug at this point…)

@wrongwright If you  are using the course start file, to see through the walls into the room backface culling has been enabled.

You probably have flipped normals,
select the object and enter edit mode, select everything with A, then press SHIFT+N to recalculate the normals.

If this doesn’t fix it, can you give more info with images or video.

Yeah the file has backface culling enabled so if you have an object that is thin and you can see its back faces, they will show up transparent, unless you disable backface culling. And if your whole object has the normals flipped, then it will be all weird looking.

You can turn on or off face culling here:

And see if your normals are flipped with the face orientation, it should all be blue, no red. If it’s red and backface culling is On, they will show transparent.

Ya….my bad.  I had added a Circle, then I Extruded to make it into a ring.  Looking through the ring was crossing my eyes.  I didn’t see any backside to it.  Makes sense now that it would be backfaced culled.  I zoomed in really close and turned off backface culling and sure enough it de-culled.  haha.  Thank you for the help.
