What are the differences between the two pictures?

Switch particleTexture with two pictures and you can see the obvious difference.I found that modifying the blendMode can solve the problem. But I wonder why the original picture seems OK.I didn’t see the difference between them :thinking:

might be that one is premultiplied on alpha meaning the color is black where you have alpha vs a none premultiplied, the color would be white where you have alpha.
