Shader NaN and Aliasing in build but not in editor

[slushieboy99]

Hi all,
I’m running into an issue in HDRP where my shader looks how I want it in the editor, but when I build I get lots of aliasing and NaN values. I’m using @bgolus Normal from Height shader technique found here:

Low resolution (or bad anti-aliasing) on Normal from Height?

Here’s an example shader graph setup. It has two properties, a “texel width” and “normal scale”. [6808766--790211--upload_2021-2-5_22-28-13.jpg] This is using derivatives to scale the width of the offsets so it’s at least 1 pixel wide. But the texel width is used as a way to clamp how small of an offset is used, so if you get really close it isn’t just always a single pixel width. I also use it to figure out how much to fade the normal by as you get further away. Most of this could be avoided…

The functions I’m plugging it into are quite a bit more complex than a simple polygon, but it’s the same principle. I have confirmed that without this normal function I do not have NaNs or aliasing. I have tried adding a slider in the build to change TexelWidth but it does not effect the aliasing resolution or NaNs.

Anyone have any ideas?

In editor:

In Build:

EDIT:
This is happening with default Normal From Texture as well, here I simply put in a sin function and get this awful aliasing:

This is happening with Subsurface Scattering off as well.

While playing around with render settings I’ve started getting the error:

Graphics.CopyTexture called for entire mipmaps with different memory size (source (RGBA8 UNorm) is 1024 bytes and destination (Alpha8 UNorm) is 256 bytes)

Not sure if this is relevant, but I’m not calling Graphics.CopyTexture anywhere so I’m not sure why this is happening. Object renders properly without any normal map plugged in. Also having the issue on both D3D12 and Vulkan.

Fixed this by setting mesh compression to none in player settings
