TUTORIAL Tree shader for day/night cycle

Hello,i had this problem in which the tree shader was looking good in the day but awful in the night,because of static values of ksAmbient and ksDiffuse. Now they can vary hour by hour. The only problem is that the change of values is instant and i dont know how to make smooth transition,despite using "lag"parameter. Anyway it's also ok like this. Here are the 2 files you need:

• Add these values in 'content/tracks/yourmap/extension/ext_config.ini'

Now,the luminosity of the trees can vary every hour. You can change the hours in which the conditions are active,depends of the sunset and sunrise hours in your track. My track has sunrise at 10AM and sunset at 10PM.
