    Runtime Virtual Textures and World Composition

    How can I use Runtime Virtual Textures together with World Composition to get it to work for all of the streamed landscape pieces?

    Figured out my RVT problems: each landscape had to have a reference to its own separate instance material -- which references the RVT asset, also separate RVT volume and RVT asset per streamed level.

      Hey, there,

      Exhuming this from outer space...

      I am also working on Virtual Texturing.

      Do you mean that for it to work I need:

      1. A separate landscape Material per level and Layerinfos for each

      Referencing to:

      2. A specific Runtime Virtual Texture

      with

      3. A Dedicated per level Runtime virtual Texture volume


      A separate Landscape Material per level is a bit tedious...

        Ok got it to work, and apparently I don't need to add new Layer Infos for Landscape layers.. not sur how it behave with different landscape materials... say it's not the same list...

          I had landscapes on different levels in world composition, using the same Realtime Virtual Texture, but needing its own volume. Seems to work well, seamlessly scattering paint and foliage/grass across the seam. Using multiple RTVT's would be way better for resolution, but may require more gpu. I would like to test this and check for seams etc. vbs it looks like you had success doing this, have you come across any issues? Anyone test this on a dedicated server with clients yet?

            rasamaya1 I have 1KMĀ² tiles I should use different RTVTs no ?

              I think you can get away with 1km easy. I was doing some testing, you need to adjust your settings in the RTVTexture, I made a grid and slowly tweaked, while doing profiling on a much much larger landscape. but... I have a good gpu. My texture size is 4194304 with virtual texture size of 4096 and tile of 1024 w padding of 1. This is huge, but works well with "my testing" so far, resolution wise on a 4km by 8km landscape. With this size, I have a checker map with a clear 10 squares across 10cm. So good enough, but thats a huge Texture size. With a smaller map, say your 1kmby1km you can reduce everything or push limits and have way more resolution than me.
