O mighty gods of Egy,~Unreal, I beseech thee, grand me peace for my questions!
I have started trying to create my own Aspen Farmland biome, Pallas’s Cats included, but I have ran into a few things I can’t seem to figure out or get google to instantly solve all of my problems;
Number one! The Two Sided Foliage system;
I have set the Scattering Color to red to illustrate my conundrum better, what are the best practices to create proper lighting for a tuft of grass? Whatever I do, it seems I always end up having the scattering be on all random sides of my model, which looks even worse when I paint them in mass;
I have tried inverting the polygon’s facing normal in various patterns, all facing the same way, all facing out, in, spherical normals, single normal facing up, but I can’t seem to solve this in any other way than simply having real polygons on the backside…Though then it seems I broke the Scatter feature of the Two Sided Foliage shader as it seems to need a double sided material to work…
Number Two! How can I exclude my grass from light mass computations? I painted 140k instances and Lightmass ain’t getting past Zero percent on preview mode.
Number Three! For performance, want to create a simple solid model to cast shadows instead of having my alpha card dense tree do the real shadow casting, is there a way to add an invisible mesh that casts shadows?
I tried adding Two meshes, one without shadows, one one with shadows and with the “Hidden in game” flag set, it seems the shadows disappear when I enter game mode regardless if I have them set to render.
And finally, Number Four! What are the best practices for creating height maps for Unreal, that work with terrain layer heightmap blend, here is how my height maps look like~
But my results are depressing:
Sorry for the question humble bundle pack, I wasn’t sure if I should make separate threads for all of them, but since they are all Rendering related, I thought this would be okay.
Thanks in advance;
