Retopology, amounts of faces

Question Modeling

How differs modelling for a mobile game and computer? Also for example, when we've created through modelling, but there were a lot of vertices, do we need to retopologize it? And is it necessary to create good quality result to use sculpting or is it possible to do through modelling? Sorry for so many questions, just been wondering about all possibilities

    Basically for mobile game is all about performance of the device, you have to optimize a lot for mobile games. For computers you don't have that same problem.

    If you need to optimize because you have a lot of vertices, one way is to retopologize yes, but there are much other ways to optimize, not just that one.

    The sculpting step is not a necessity, you go go straight to modeling if you want, it depends on the workflow and pipeline. Normally for the more free flow initial stages you do sculpting because things change a lot, and before you commit to a model, you first sculpt because it is more flexible for changes.

    Retopology is a skill and a topic of its own. It all depends on what you want to do with the model if you retopolgize or not.
    For a game, as Omar said, Yes most definitely.
    For a single image render to show your friends, No

    There is no "amount of faces" that is the right number, it depends on the model. If it has lots of detail or even if it will be animated like a character for example.

    This raise other topics too,
    Texturing - are you going to need to UV unwrap to use textures
    Baking - Often small details will be baked to a normal map from the original sculpted mesh and used on the retopologized mesh.

    You will learn a lot about retopology by learning poly modeling and also animation. With animation you need edge loops correctly placed to help with the bending and deformation of the model, specifically character models.

    I hope this answers your question, and you will learn more about retopology as you become a more advanced modeler.

    What other ways of optimatisation?


  • Omar Domenech replied

    That could fill a whole book. As you practice and get into uncomfortable situations and limitations, you'll start getting into the need of optimizing and you'll integrate it into your workflow from the get-go, you just need to practice a lot and start learning a lot. So devour all the curses you can 🤘🏼
