You configure Unity to override the mipmap level of a texture using the following:
Follow these steps:
When Unity needs to reduce mipmap levels to meet the memory limit, it considers textures in priority order from low to high until it meets the limit. This means textures with a higher priority value are more likely to keep their higher-resolution mipmap levels.
Unity removes a mipmap level of a lower-priority texture every time it considers textures at that priority or higher. For example, if you set one texture to a Priority of 1 and another texture to a Priority of 5, Unity might remove four mipmap levels before it considers the second texture.
You can also use the following APIs to set the Priority value:
Use the following APIs:
You can use the Mesh.GetUVDistributionMetric
API to get an estimate of the UV density of a meshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info
See in Glossary. This helps you calculate the mipmap level you need, based on the position of the cameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info
See in Glossary. For example code, refer to Mesh.GetUVDistributionMetric.
Use Texture.streamingTextureForceLoadAll to load all mipmap levels for all textures.
