Importing texture into shader graph doesn't look good

[iron jolt]

I have this texture that I want to import into shader graph, and it looks fine in the importer, but in shader graph it looks completely different and acts completely different. How can I fix this?

Importer preview shows it with alpha transparency, SG node preview shows it without alpha
Neither are directly representative of how it'll appear in the scene on a material

Though you're not using the alpha output for anything so reality is closer to the node preview

Same for texture dimensions

i see, so how can i use the alpha transparency? because this looks really ugly 😭

Open texture settings

Generally all you need to do is plug (A) output into the block Alpha input

The result can still change if you modify the alpha between those, or if you have enabled alpha clipping with some odd Threshold (not close to 0.5)

im trying to make a mask to fill a shape, so im using the alpha already. this probably isnt the most efficient way to do this though

the first 3 blocks are just trying to get the "whiteness" of the image lmao

I don't understand what this is meant to achieve

Alpha of the sampled texture is unused

im trying to make a fill sorta thing

using the gradient as like the sample

That's a bit messy for sure, but it'll probably work like you want if you Multiply the One Minus output wth Sample Texture A output before passing into Alpha input

seems to work better, but there are some clipping things. maybe thats because of the image anti aliasing, thoughj

More or less
Depending on how the texture was made, disabling "alpha is transparency" in texture import settings may fix it (or may make it worse)

A solution would be to extend the gradient in the image out into the transparent areas as a safety margin, and save the image in a way that doesn't scrub out the color values of alpha 0 pixels

"Alpha is transparency" setting attempts to extend the color pixels in just such a way, but fails here possibly because the're unexpected antialiased pixels bordering the gradient's opaque area

Many image editors assume you don't care about color in transparent pixels and replace them with white which causes problems in tech art
