Loosing part of my model why? Help please

I am exploring how to import models from C4D, after bringing this model in it shows only part of it.
Is there anything I am not aware of thats causing this issue.
• Wondering if some of it is related to the camera hiding items to show Lepz I am using the 3D Platfom Tutorial files as my sandbox
•Strangly enough the model shows in full when viewing from unterneath?
What am I missing?

Thanks for any suggestions.

hi

play around with normals
the outer part looks right for me, but try to flip the inner_ring_normals and the top_normals, should fix your problem
most shaders in unity are “singlesided”
thers a nice preshader “Nature/Vegetation Two Pass” to render both sides of your object.

If rotating the camera shows your missing parts of the objects then is because the shader you are using is culling back faces (faces that has normals pointing away from the camera).

If not, it probably has something to do with the format you are using, try exporting to something else like FBX.

Both the above answers are good ones IMO, the only other possibility is that you are using instances, which are not transferring, in which case your model copies have to be actual objects.

Thanks that worked fine, saved me a lot of time trying to work it out.
Rotating the floor made it apear from the top, don’t need to see it from below.
Better read up on Normals!

One more question then as I have a continous ring wall there
does that mean I should contruct diffentently am I better of breach the ring into its componant walls?

whats a good rule of thumb of how to brake down modeling should I try to built singl large models or break it down as much as I can?

The sweet spot per object is around 1500-6000 polygons roughly, so combine if they are lower. If you wanted a section to fly off as part of an explosion or similar, it would need to be its own object…

Thank you all for the quick help, much appriciated.
