Hello,

I'm new to Amplify and still wrapping my head around how transparency is handled. I'm currently looking at making a shader with multiple PNG sprites with transparency layered on top on each other. I've experimented with add & multiply, as well as different blend types & modes and have yet to find success.

What I would like to achieve as a result is simply for one texture to sit on top of another, without blending in any way, as seen below:


I want to avoid masking or blending, like this example:

Any idea how to accomplish this? I feel like it should be possible, but I can only seem to find nodes & settings that will blend, instead of layering on top of, like I am trying to.

Hello, one possible way to accomplish this is through setting up a mask as the interpolator for a Lerp node, please refer to the example below:



I'm using the relay node to show a preview of the mask being used, which has a value of 0 or black where the A input's texture is present, and 1 or white for the B input's texture.

You can also check out our SingleChannelMasking sample for a more complex case in which several masks are used, as well as the SpriteMask or MaskedUI samples for examples using each of those specific templates.

Please let me know if this helps!

Thanks for the reply Amplify_Borba,

Your example does help. I didn't realize that the alpha input of the lerp node worked that way. The lerp node will allow me to do what I need to do.

Glad I could help!
