Based on the previous geological work, a large number of granitoid samples are carried on the Sm-Nd isotopic analysis. The results show that the εNd values of these granitoids occurred in Beishan Mountain area range from-16. 39 to +10. 89, some of which are characterized by the positive εNd value. It suggests that the crustal growth existed during Phanozoic in Beishan Mountain area, just like other regions in the CAOB.

So we either need to remove the gamma from our textures ("linearize" them) before rendering, which can be done with a gammaCorrect node in front of them in the shader chain with Gamma set to 1/2.2, which is 0.455 rounded important: the gammaCorrect node works inversedly - the value we put in there is the desired gamma compensation value, not the actual gamma function itself!

所以在渲染之前我们也需要把纹理的Gamma值去除，这些可以在材质系统的前面用一个Gamma校正节点来完成，将Gamma值设置为1/2.2，就是0.455（重点：GammaCorrect节点使逆向工作的---在这儿我们输入的数值是期望得到的Gamma补偿数值，不是实际的Gamma自身的作用数值！
