Yes very true, as for tips::
I would say don’t add too much detail in the beginning of the modeling process. Blocking out your forms and getting the proportions right are key. Even if the model is missing a few things, proper proportions will help make up for that.
References, references, references, the more you have on the subject, the better the out come will be. You may think you know alot about what you’re doing, but there’s always something you may miss.
Polygonal modeling can be very efficient, so push your points, poly face and edges to the limit before adding detail, and then repeat.
If you’re going to use a texture map, setting out the UVs early can help. I would say about mid way. Waiting until the end with all that detail already added may leave you with alot of pain.
Save your file in stages, ex:: David01 , David02 , David03 and so on. This will help if you’ve messed up and don’t wonna spend your time trying to get things back the way it was. It can be easier to go back a stage and start from there, or even take what you like from the file you were working on and merge/import it into another.
These tips are relative of course, everyone will have there own way of doing things, but I thought I would share how I go about doing my models.
