You can't make parameters for speedtree nodes so you could make a master material as long as all the materials share the same speed tree settings like you could have a master for grass maybe but would need a different one for trees etc(vertex colour node would be the same anyway)
Also you probably have but just in case make sure your shader model is set to two sided as well as masked, two sided foliage. Also try multiply your normal map with a two sided node hope some of this helps haha I'll throw something together tomorrow and see if I can recreate the issue for you
Finally an update: I did the initial foliage pass on the scene, but to me it seems to contrast a bit too much with the stone props. I feel like part of this is due to the fact that the props have not yet had their dirtiness/variation texture pass yet as they do in the original 'concept'. I am hoping after dirt, damage,…
@Adelphia thanks heaps for the great help man! It's so strange I feel like I have a very similar set up, I really think that Speed Tree has messed with something a little too much and I might be better off doing it again and hoping it doesn't happen! Here is my Material: The constants in the middle are just experimental,…
@Stavaas @Adelphia @ZacD @anMori Thanks for all the comments and suggestions guys. I took it all on board and adjusted the lighting, post processing and fog a fair bit, and I think its starting to look somewhat souls-ish. (Only the above image has had the FOV adjusted) There is still a bit of tweaking to do (UE4 High-re…
