RenderTexture.autoGenerateMips

Name	Type
autoGenerateMips	boolean

Description

Mipmap levels are generated automatically when this flag is set.

Extra Detail

When a render texture is with mipmaps (useMipMap), then by default rendering into it generates all the mipmap levels. The mipmap generation happens automatically only after rendering into this render texture; when active render target is switched to some other render texture.
