Requirements for game level/character design

Requirements for game level/character design

Hi all,

I wonder, if there is a good 'rule-of-a-thumb' for amount of triangles for models used in indie games? I understand that the answer depends on many different parameters, but still...

When I start modelling art for a game I approximately know:

approximate amount of active objects (characters) on the map

approximate level design idea (from large scale (mountains) to small passive objects (small rocks, furniture))

How can I decide which detail level to give to each of these? Where do I start?

I.e. I don't want to end up remaking characters models because they are too high-detailed and the game is running too slow on average computer, neither I want to make low-detailed models to see in the end that they could have been made much more detailed.

The same problem with level design. E.g. I can make ugly low-poly pillars which could have been made better, or I can make high-detail pillars just to see that 100 of them bring FPS to zero...

Is there any practical 'golden rule' for such considerations? Or a kind of 'real-life' test for the engine?
