Splitting Polygons - Terminology and how to avoid?

Recommended Posts

Hi Everyone,

 

I'm still fairly new at this, hoping someone can help me here. 
When modeling, I notice that some of the polygons appear broken or split when rendered. I understand what it is caused by - all four vertices being on different positions in all three axis. I am not sure what this is called so I did not find help when I googled. 

Is there a workaround or a way to get rid of this? Or are there rendering settings I don't know about? This was rendered with the default rendering settings. 

Thank you in advance!

These polygons are called 'non-planar', which is an error-state in geometry this low-res. I'm afraid it's just sloppy modelling where you haven't paid enough attention to keeping these things planar as you create them. You can use the mesh checker to highlight which polys are not planar (Modelling Mode of attributes menu / Mesh Checker).

 

How to make a poly or group of polys planar again ? Select that poly or polys, change modelling axis to Normal, and zero-scale (scale tool hold shift to quantize) on relevant axis having first moved it to the minimum position in that axis (also in that window).

    Thank you for the clarification, this helps a lot. 
    Is there a technique or tutorial you can recommend in order to avoid this?

    Learning modelling in Cinema is a years-long enterprise, so you won't find a tutorial that will just cover such a tiny elementary detail such as keeping things planar ! But there are lots of good basic modelling tutorials to help you get started. Here is a good one, although you should watch the whole series ideally, and preferably in order from No 1 - Interface.

     

     

    Note: as good as it is, this is quite an old series now, so some tools will be slightly different in your version, but the essential techniques remain useful.

     

    You can learn to a rather better level by following contrafibbularities on youtube, who has probably one  of the best modelling channels there are. Likwise Arrimus 3D, although he is working in 3DSMax, so best not to watch those until you are utterly familiar with Cinemas modelling toolset, and how it differs from Max's...

     

    There are paid tutorials too, which generally have a lot more information in 1 place, and the better of those includes things like the Making it Look Great series..

     

    Or you can save yourself a lot of time and get a modelling 101 personalised jump-start skype session or 2 from a modelling specialist (like me as it happens! :)) See my profile for further details...

    Thank you very much, this was very helpful!

    I will keep all of this in mind.
