public static void DrawPreviewTexture (Rect position, Texture image, Material mat= null, ScaleMode scaleMode= ScaleMode.StretchToFill, float imageAspect= 0, float mipLevel= -1, Rendering.ColorWriteMask colorWriteMask= ColorWriteMask.All);

파라미터

positionRectangle on the screen to draw the texture within.
image Texture to display.
matMaterial to be used when drawing the texture.
scaleModeHow to scale the image when the aspect ratio of it doesn't fit the aspect ratio to be drawn within.
imageAspectAspect ratio to use for the source image. If 0 (the default), the aspect ratio from the image is used.
mipLevelThe mip-level to sample. If negative, the texture is sampled normally. Sets material _Mip property.
colorWriteMaskSpecifies which color components of image will get written.

설명

Draws the texture within a rectangle.

If mat is null (the default), an appropriate material will be chosen for a RGBM or doubleLDR lightmap or a normal map and the fallback blit material will be chosen otherwise.
