Hi,

Looking for some clues about the use of Normal maps when creating original characters. I've been looking over what is included for both L'Homme and La'Femme and I'm not seeing ANY Normal maps used. RPublishing uses just Bump and Specular while 3Dream only uses a highly detailed Bump map. Coming from the DAZ Studio side I really like L'Homme and want to make a character for him but if I do not need a Normal map, so be it. I just wanted feedback about the reasons why Normals don't seem to be very popular for making characters. Seems that DAZ Studio surfaces with iRAY just get so complicated these days so if I can get away with creating a realistic character without all the extra maps that would be just fine to me.

Please advise.

Thanks so much Richard

Quoted from BagginsBill:

"Look I've explained this before but for some reason it doesn't reach everybody.

Normal maps are a hack for real-time game rendering from olden times. We don't need to use them. Normal mapping from normal maps does not give you any different results than normal mapping from bump maps, assuming both are done correctly. But that assumption is rarely valid.

Poser doesn't use normal maps correctly. Poser does use bump maps correctly. As a consequence, no matter how you make your normal map (there are "right" ways and wrong ways), the result will come out different. It should not be different.

Bump maps are normal maps without the pre-baked math - the renderer does the math on each render, which takes a few dozen extra milliseconds than the normal map. But the bump map comes out right and the normal map does not. This is because the pre-baked math is not fully agreed upon by every 3D program.

Half the 3D programs use normal maps differently than the other half. All of them produce their normal maps from bump maps.

Therefore the only logical thing to do is just use bump maps."

Thanks very much!

This was the most useful explanation of "normal maps" I've ever read!

I've read a lot of mumbo-jumbo in the past, but never it was made this clear (probably because the posters hadn't an idea either).

Thank you@BagginsBill for making this clear in a way that even dummies can understand it,

AND:

an extra "Thank You!" @Kalypso for reposting this!

Thank you Spock ;)

A huge on this one.
