制作剑柄的金属效果,在shader basic parameters(明暗器基本参数)栏下,选anisotropic(各向异性)

回到standard编辑层级,在reflection通道中的贴图按纽选fall off,在front side中第一个色块选metal(lume), reflectivity(反射率)0.5
在front side第二个色块中选metal(lume), reflectivity(反射率)1,并将反射的amount(强度)60

下面做光刃,将diffuse和specular都调整为白色,单击diffuse的贴图按纽选fall off,在front side中第一个色块255,140,140
在front side第二个色块中选glow(lume),将surface material设为1,0,0;diffuse设为0.57,0,0;transparency设为1
