I'm trying to wrap my head around how to do a shader that supports standard transparency in portions of a texture.

For example, I have a plain white square with transparency in the center, but I can't get it to render correctly with the center being transparent.



At the moment I just have an Sampler2D texture connected to Albedo and I have the shaders Render Type set to Transparent and Render Queue to Geometry.

What else do I need to do?
Thank you

Hello,

We would be happy to help!

Is the Alpha channel connected to the opacity input?

Thanks!

Ah, thank you. I had tried connecting the Alpha channel to the Opacity input previously but it still wasn't working. After your guidance I kept that connected and discovered that I needed to have Blend RGB set to Alpha Blend. Now all is well.

Thank You!

Actually, one more question. In my Editor view, it shows transparent like it should.

But when I'm in the game view seeing what the game camera see's, my transparency is black?!

Hello, could you test using Transparent as the Blend Mode, in order to use its default settings, and report back if the issue is still present? I've attached a screenshot below as reference.



You may also check out Unity's documentation regarding Blending, it has plenty of useful information regarding this feature.

Please let me know if you have any further questions, thanks!

Changing the blend mode to Transparent does make it appear transparent rather than black, but then the Render queue is wacky because I want it to use a render queue of Geometry. If I have a 3d model that I use this shader on, then the models appendages render out of order and it looks wrong... :/

Hello,

Can you share a sample for further examination?

Thanks!
