Landscape performance issue

[Deathrey (DeathreyCG)]

an I ask how you dealt with the Texcoord Frac, Mipmapping and/or Texture Filtering issues related to using a texture atlas?

Essentially, I did not deal with it. Ended up using padding(worth 1/8 of texture space) and capped lowest mip, before switching to arrays. Top down view was forgiving in that respect. That is not a viable solution for quality FPS/ third person.

• Would texture arrays “just work”

Yep. Can’t say definitely about specific PR though.

• Since Dynamic Flow Control is backlogged, what’s the best way to use it without ending up with your entire material in the Custom node?

Back then we ended up bypassing material editor for terrain shader completely.
Besides that, You do not really have other options.
Now I think it might be possible to modify MaterialTemplate.USF, adding an include with terrain shader code and set of ifdefs, to be later called from custom node, which also does define.
