Re: diffuse, specular, normal maps all the time!?
I'm not sure how to explain this and how it would relate to the game industry but for prerendered work having access to a gloss map is very helpful. It's also kind of hard to explain on how to use it since you can do so much with it when combined with a color, spec color, specular map and bump. Sometimes you don't want the… -
Re: diffuse, specular, normal maps all the time!?
Do you have any idea the amount of time that takes to actually do? Are you seriously also suggesting using a gloss map, *isntead* of a spec map? Any decent engine will have gloss settings per mesh chunk/shader. How you could posibly go without the detail and color of an actual spec map is beyond me, your asset would look… -
Re: diffuse, specular, normal maps all the time!?
Don't most people have that in their shaders these days? A spec map, a spec strength and a spec falloff? -

Re: diffuse, specular, normal maps all the time!?
You use a map when you want to change the spec power across a surface - say for shiny buttons (tight, hot spec hits) on a jacket (soft, wide spec hits). -
Re: diffuse, specular, normal maps all the time!?
Yes, it's sometimes referred to as specular power, cosine power, cosine falloff or glossiness. Cosine power is the most approriate term because it best desribes the math behind it. We either set it on a per-shader basis (set the spec power) or with a per-pixel map, usually stuffed into the alpha of the spec colour map. I… -
Re: diffuse, specular, normal maps all the time!?
[ QUOTE ] If your specular strength is simply a 0% - 100% range, then brightness of the spec color map does the same thing as the multiplier. You're double-multiplying it, which can be nice I guess, it doesn't all have to be in the bitmap. [/ QUOTE ] It can be very nice, because if you are using a fairly grey and dim spec… -
Re: diffuse, specular, normal maps all the time!?
[ QUOTE ] With the actual hardware, to be bothered with the budgets is really silly, imho [/ QUOTE ] Well, sorry to say it, budgets do matter. EA might have superb 20,000 polygon boxers in Fightnight 3 with loads of sexy shaders, but thats 2 men in a room. Unreal, GOW, Rainbox 6, Tony Hawks - those games using big… -
Re: diffuse, specular, normal maps all the time!?
[ QUOTE ] Rick: Surely spec maps and spec strength are the same thing? [/ QUOTE ] You think that, but no. The strength is basically just a multiplier that works with the map. -
Re: diffuse, specular, normal maps all the time!?
no i'm not suggesting gloss INSTEAD of spec map. i want both but i'm saying gloss can be more important than spec.
