Hey there,
We’ve encountered an issue where rain effects from windshield materials are visible through decals placed on top of them. For instance, on the C-17, the rubber seals around the windows are implemented as decals (draw order 10) and physically separated from the windshield geometry by several centimeters. Despite this, the rain droplets continue to render over the seals.
We’ve tried multiple potential fixes, including increasing the decal draw order, but the problem persists.
Pls keep in mind that this bug has been brought up by MS QA, and we are expected to find a solution asap.
Hello,
By design, decals are drawn only on hard surface (opaque materials with alpha = 1) unforunatly what you are trying to do is not possible. Decals are not meant to be rendered upon a windshield material.
Thank you

As non-decal (standard material with alpha), the issue persists. This setup should be possible, right?
Hello,
I am not sure to understand your issue here, can you send us your project or an example model with the sources in private message ? See 3) Provide Private Content
Thank you
Will do shortly. Any overlay with transparency (either decal, or standard material with Alpha set to Blend or Mask) will result in a similar issue with rain postprocessing.
