sorry but its just not working for me.
i start a new blank project in 4.13.1
then i copy the folder texturefog to the projects contentfolder.
if i start the project the next time, all textures are missing in the materials and in the MF_FOGFLOW_01 Material Function all textures are missing, too.
as i dont know which textures have to be in what slot, i just cant play with your cool fog system…
i just dont understand why you cant reproduce these problems …
kind regards
stucki
