Transparent Plane with Screw Modifier I'm having trouble making a plane using the screw modifier transparent, because &quot;the plane&quot; is shining through?
In this video, using an old version of Blender (2.78), it looks as easy as enabling transparency, and adjusting the alpha https://youtu.be/owid9yrq97s?t=2494
However in the &quot;new&quot; version of blender (2.92.0), it seems they've quite reworked the way materials work. I've created a material that uses an Emission and Transparent BDSF shader, through a mix-shader, so I can adjust the transparency, and while it's working great for &quot;solid?&quot; objects, it doesn't work for the object using a screw modifier:
I've tried to create a minimal example below:
Fac (&quot;alpha&quot;) 1 is great. There is no transparency.

But when I adjust it down.. I get two different colors.

I'm using the screw modifier for the object, so I imagine that it's being drawn over itself? And that I'm seeing the object over itself. Because if I delete one of the vertices, like in the gif below, suddenly I get the color that I want? But then I don't get the shape that I want anymore.

Furthermore I would really like to keep using the screw modifier, so I can lock different angles to keyframes and do the &quot;radial animation&quot;-thing.
I've tried enabling Backface Culling, it has the same result as deleting the vertice: (I reckon it's probably not &quot;the same,&quot; but it looks identical.)

Disabling &quot;Show Backface&quot; and &quot;Backface Culling&quot; gives this really weird color, that I believe is due to some clipping:

It feels like I'm missing something super simple, but I was at it for 4 hours the other day, and since I very recently picked up Blender, I'm simply not aware of what tools I have at my disposal.
I've tried searching online, but I'm just not sure what I should be searching for, &quot;transparent plane screw modifier&quot; isn't giving me anything other than tutorials on the &quot;screw modifier&quot; or &quot;transparent planes.&quot;
Thank you.
PS: I am using the Eevee render engine. I don't know if this bears significance.
Alright, so I'm not entirely happy with this solution, but maybe I should be?
I've managed to work around it by.. enabling Backface Culling on the material:

I've been here before, but I also noticed that you can &quot;flip normals&quot; under the Screw Modifier:

Now I can duplicate the shape and remove the Screw Modifier:

.. and finally set the &quot;plane with the screw modifier&quot; as a parent object:


Setting it as parent isn't strictly necessary for the color part, but it makes it quite nice to scale and manipulate otherwise...

If anyone has a good solution that just uses the single object with the screw modifier, I would like to see that!
This feels quite hacky, but &quot;if it's stupid and it works, it's not stupid&quot;
