Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Default Texture on Landscape Sectors (Mobile)

I'm having a rendering issue whenever I look at my landscape in Android preview mode. There are large sectors of default material, and I can't seem to figure out the reason for it. It's far from my most complex texture in terms of instructions and textures (so I assume it's not an issue with the texture itself). I don't work with landscapes often. Is there some limitation of Landscape size in Mobile that I'm missing? is there a way I could increase the size of the sectors (would that fix it?). Additional information below.

The material stats are

Base Pass Shader: 102 instructions

Surface Lightmap: 119 instructions

Volumetric Lightmap: 175 instructions

Vertex Shader: 36 instructions

Texture samplers: 4/16

Texture Lookups (est.): VS(0), PS(1)

User Interpolators: 2/4 Scalars (1/4 Vectors) (TexCoords:2, Custom:0)

The water texture has over 3x the instructions, 3 more texture samplers, 8 more PS lookups, but 0 Interpolators. Is this error something to do with usage of Landscapes on Mobile? or the Texture itself?

This isn't a really great answer for using landscapes in Mobile but I found a workaround:

Using static meshes with custom UVs to mimic landscapes in Mobile since it looks like Mobile just doesn't like landscapes for some reason and it worked out just fine.
