Texture2D imageContentsHash error during build

Hi, I am using Unity 2018.3.8f1 and getting an error while building that says: "Type 'UnityEngine.Texture' does not contain a definition for 'imageContentsHash' and no extension method..."

It is the same error that was reported here:
https://issuetracker.unity3d.com/is...r-texture-dot-imagecontentshash-when-building

Any reason why this issue is still occurring during a build?

 

This is poorly documented and the error raised should be more meaningful. The answer is buried at the end of a paragraph in the middle of the doc page for the parameter:

For regular textures, Unity first computes the hash when the texture is imported into the Editor, and updates the hash after light and reflections are "baked" into the texture. If you subsequently render into a texture which is used as an input for the Global Illumination system (such as sky, light or reflection probes), then you must update the texture hash yourself. Note that the hash is an Editor-only property.​

Bolded italics mine. This is basically an exposed internal parameter for the editor so that the *editor* knows when a Texture is updated (for example, in cases of third party tools modifying the texture).

I updated the Issue with a comment that explains this for anybody that runs across it in the future and submitted a suggested change to the documentation. It's pretty unfortunate... Hopefully Unity fixes the raised exception and improves the documentation. It shouldn't require a meticulous reading to determine that the parameter isn't supported at Build time.

 

Oh ffs. Just wasted an hour on this.
