First array element in inspector rendering below other elements.

Question

I was following Sebastian Lague's procedural planet generation series from a while back. I was on episode 3 and I ran into some weird inspector rendering. There was a public array and the first element always rendered below the others like this: https://drive.google.com/file/d/1KIC3Dti-uCAwZO_pV3wk2UM75DBvl58s/view?usp=sharing. It only happens with the first item. The rest work fine.

Here's the github page I was referencing to write the code: https://github.com/SebLague/Procedural-Planets/tree/master/Procedural%20Planet%20E03/Assets

Looks like this is a known issue according to the community: https://issuetracker.unity3d.com/issues/first-array-element-expansion-is-broken-for-arrays-that-use-custom-property-drawers

However, there is a workaround by using [NonReorderable] on your array. You won't be able to reorder it, but at least it can be edited. (Noted by KWIKDEV on the link above - thank you!)

     [NonReorderable] public AnimStruct[] anims;

Not a solution, but at least you can continue development.

Oh that's cool. I didn't know about the property workaround. I don't really need to reorder my array so I'll try that. Thanks.

If anything, I'd say this is an issue with the version of Unity you're using. If it's not an LTS, bugs tend to pop up more frequently. It might be the safest bet to download the latest LTS so as to avoid bugs like these, especially if you're using an alpha or beta version of Unity.

I'm using version 2021.3.3f1. I don't know if there have been any reports of arrays doing weird stuff in the inspector. It could be a problem with the editor scripting in the github page, but I'm not too knowledgeable about that stuff. https://github.com/SebLague/Procedural-Planets/blob/master/Procedural%20Planet%20E03/Assets/Editor/PlanetEditor.cs
