How to create PBR Combined (TextureName_C) Texture?


I would like to know how can we create PBR combined (TextureName_C) texture for Flight Sim World use? Hope someone can help me on this

The SDK ( has the related info but i am not quite understand the procedure.

Hope someone can clearly explain this part:

Are the values of Gamma for
1. sRGB to liner=0.45 and
2. Linear into sRGB=2.2

are fixed? Or, we need to follow the formula written in the "Converting a value from sRGB to linear" section for each texture we created to get the Gamma value?

Please clarify.

Thank you,
