Yes I’m new to Unity, and yes I’ve tried researching within the forums on how to do this.
I have a simple plane with a texture on it, and I also have a seperate black and white jpg image that I would like to use as an alpha channel for this plane, so parts of would be transparent. All I would like to know, is how to apply this black and white image to its alpha channel within unity.
Thank you so much, and sorry for such an amature question. :]
Go into Photoshop or some other image editing program, select the alpha channel, or in this case create one, then copy/paste the black and white image into that channel, then save the file in a format that allows for alpha channels (.bmp, .tga, .png etc.).
Inside Unity you can also use the texture to generate the alpha, but that’s not what you’re wanting in this particular case. But make sure that option is switched off when you import your new image, or Unity wont recognize it has it’s own alpha channel.
Thank very much kind sir, this has been useful.
Though I did what you said in photoshop and saved the new texture out as a png, and I think Unity isn’t recognizing that it has its own alpha channel, like you said. Not sure how to make it recognize the alpha channel.
Also I have the object’s shader set to Transparent/Diffuse… is this correct?
Thanks, I really appreciate the help!! :]
Save it as .psd. Also, when using .psd files, sometimes the importer doesn’t get the alpha channel right unless there is an actual background layer.

yay! bravo, that worked!! Thank you!!
Though why wouldn’t it work with a png file?? hm
PNG files don’t save the alpha channel separately like that.
