Model from Blender - how much is too much?

Hello all,

If this has been answered, my apologies. I did do a search and didn't see anything that addresses this specifically, so....

This is a best practice question I guess. When I create my model, should I add bump maps? I know Blender has all this stuff for pretty renders, but this is just a game asset, so I'm not sure how far I should go. I can add materials and some texture overlays for interesting detail (decals), but I'm really itching to add some bump maps for that extra zing. But, I'm wondering if that's really a good idea.

While I'm in the neighborhood, I'm guessing I don't need to bring any lighting with me since Unity has its own very powerful lighting system. I *could* bake in some, but seems like I really should just let Unity light the game scene. (Yes, no?)

Thanks for any guidance!

 

Sure, bump maps (called normal maps in Unity) very often add a nice level of additional detail that can't be reasonably obtained any other way.

And yes, I agree you should let Unity do the lighting.

 

As long as your not targeting mobiles, your fine probably to use unity's lighting systems. If you do target mobile - consider alternatives to improve performance for little phones and weaker tablets.
