How to use a png without the black background in 2.81 and cycles

I tried to use alpha blend, but unfortunately without a difference!

Can you elaborate your problem. It will be best if you post a screen shot

so its a png but the background is totally black

I still don’t understand which workspace or editor type you are in. Did you use shift + a to import your image or is the image applied to a mesh as texture?

If you using principled shader just plug image Alpha channel to shader alpha channel, and if you using other shaders you have to use Mix shader with Transparent shader and plug alpha channel to the mix shader fac

Moved this in a better fitting category.

I will try it, thank you!!

im in the shading editor and added the picture to the unwrapped object with uv-editor. and i importet with open at the image texture (shading)

Like higgsas said, it will work just fine.

awesome thank you it works!! But now is there any chance to get the background white?2020-01-15_11h37_45
