Despu\u00e9s de un feedback que me pareci\u00f3 bastante fruct\u00edfero en cuanto al uso de specular maps. Aqu\u00ed anexo el res\u00famen de la conversaci\u00f3n.<\/p>\n

 <\/p>\n

\n
\n
El occlusion map de crazybump funciona para los normals en objetos planos, especialmente, ser\u00eda el equivalente a un cavity map<\/div>\n<\/div>\n
\n
pero no toma en cuenta la posici\u00f3n ni la topolog\u00eda del objeto<\/div>\n<\/div>\n
\n
especialmente de los personajes.<\/div>\n
<\/div>\n<\/div>\n
<\/div>\n
\n
\n
Especialmente terrain, m\u00e1quinas, placas tileables, texturas,\u00a0para detalles como tornillos,\u00a0botones, etc.<\/div>\n<\/div>\n
\n
pero en personajes no sirve<\/div>\n
<\/div>\n<\/div>\n
<\/div>\n
Por que no toma en cuenta tampoco la posici\u00f3n de los objetos en relaci\u00f3n a si mismo.<\/div>\n
Un ejemplo:\u00a0http:\/\/www.cocoalopez.com\/wp-content\/uploads\/2012\/04\/Tank1.jpg<\/a><\/div>\n<\/div>\n
<\/div>\n
Las texturas de los detalles peque\u00f1os todas se hicieron en Crazybump<\/div>\n
<\/div>\n
<\/div>\n
En una textura cuando la variaci\u00f3n de brillos es m\u00ednima, todo aparenta ser del mismo material.<\/div>\n
<\/div>\n
<\/div>\n
Un experimento para entender c\u00f3mo funcionan los specular maps que se me ocurri\u00f3 es:<\/div>\n
\n
\n
“Agarra la grasita de la nariz\u00a0y pon tu dedo encima de un pl\u00e1stico,\u00a0eso deja una huella que opaca\u00a0tons esa huella ser\u00eda un RGB 26,26,26 por ejemplo cuando el material base del pl\u00e1stico sea un RGB 128,128,128”<\/div>\n
<\/div>\n
<\/div>\n
“Ahora haz lo mismo en un pl\u00e1stico matte, digamos la supericie de tu mouse, que ser\u00eda un RGB 40,40,40, la grasita de tu nariz dejar\u00eda una huella de RGB 80,80,80”<\/div>\n
