根因分析

导入或分配的高度图纹理分辨率与地形配置的分辨率不匹配（必须为 2 的幂加 1）。

English

Importing or assigning a heightmap texture with a resolution that does not match the terrain's configured resolution (must be power of two + 1).

解决方案

  1. 在地形设置中更改地形的高度图分辨率以匹配导入的纹理。例如，如果纹理是 513x513，则将“分辨率”设置为 513。
  2. 使用脚本将高度图纹理重新采样为正确的分辨率：Texture2D resampled = new Texture2D(513, 513); Graphics.ConvertTexture(original, resampled);

无效尝试

常见但无效的做法:

  1. Manually resize the heightmap texture in an image editor to 1025x1025. 45% 失败

    Unity expects heightmap resolution to be 2^n + 1 (e.g., 513, 1025, 2049). Arbitrary resizing may still be incorrect.

  2. Delete and recreate the terrain from scratch. 20% 失败

    This is time-consuming and does not address the resolution mismatch if the same texture is used.
