With the changes to the texture of Frog Spawn in the recent beta, it is now using a blending render method. This appears correctly without Ray Tracing, but with Ray Tracing all blending material blocks use refraction as well, so the renderer treats even the 0% opacity pixels as a surface instead of not rendering them. This leads to breaking the intended visuals of the block when Ray Tracing is on.

Steps to Reproduce:

1. Create or apply a PBR resource pack to Global Resources that has the required texture set files for frog spawn (such as the ones I have attached), and open a world with the Wild Update experiment turned on.
2. Place Frog Spawn and observe.

Observed Results:

The portions of the texture meant to be fully transparent act as a surface with RTX on and cause the block to appear incorrectly.

Expected Results:

Frog Spawn should only render the parts of the texture that aren't fully transparent as a surface.

One possible way to fix this would be to allow resource pack creators to control if a block that uses a blending material uses refraction or not, through a component in the blocks.json file. This would allow addon creators to create blocks with blending materials without inherently using refraction.

Here is a link to the PBR resource pack I used to demonstrate the issue:
