I have a texture with alpha format as TGA. When I connect to the color channel in blender, it is not displayed correctly, only the pattern in the alpha area is displayed. why?
The texture link is displayed normally in Maya
which blender version?
what renderer?
texture settings?
some more info would be nice here…

blender version is 2.92 ，Render in EEVEE ，The texture is a color texture with alpha channel, the format is TGA
Not entirely what I meant, byt have a look here:
Material Settings — Blender Manual
Image or Movie — Blender Manual
Also, in my tests (I don’t use 2.92 btw…) it just works for Eevee. Alpha is ignored, until you set the material to a alpha setting. Also, you can set the texture to ignore the alpha too in the N-panel.
Try an older version of Blender to see if you can replicate it. Or upgrade to the latest 2.93 beta?
It looks like you need to UV unwrap it first
go into edit mode, and press U > unwrap, and it should display
uv has been expanded
I got it
