Blend Alpha?

Hi folks.

I have this texture wrapped around a sphere.



Is there any way to blend the alpha channel from 255 to 0, white to black?
I have the film set to transparent, so I just need the darker areas to become gradually transparent. I can’t use a glass node as I don’t want to see the back surface.
I can write code to change the channel per pixel after I’ve rendered the image, but wondered if it could be automated in Blender.

Thanks.

Sorry about the Thumbnail, I’m not sure what that is!

If I understood you correctly, you want to have a transparent/nontransparent object based on a noise texture. And you only want to see the side that you’re facing. If that is the case then this Solution will probably work for you. I added a Colorramp to increase the contrast of the Texture.


Hope this Helps
