title: Does current 64-bit Unity 2020 still support 32-bit (x86) native DLLs?
body: <p>Does current 64-bit Unity still support 32-bit (x86) native DLLs?</p>
  <p>I have a large x86 DLL with a nice C API, and an Interop file in C# that works perfectly, except in Unity. I've set all the options I can find to x86, and I've tried putting it in Plugins/x86.</p>
  <p>Either it just doesn't find the DLL, or it finds it and complains that I need to convert it to 64-bit. But I can't do that.</p>
  <p>Either (a) somewhere is a key factor I'm missing or (b) it can't be done and my project is dead. Which is it? A bit of sample code or a tutorial would help. I'm out of ideas.</p>
  <hr />
  <p>The key to my question is that this is only about Unity, not about the general issue of x64 vs x86. The other questions are irrelevant.</p>
  <p>And the answer is: No, you cannot use a 32-bit DLL in the Unity Editor but Yes, you can use 32-bit DLLs in a build of Unity with an x86 target. Unity allows you to provide multiple DLLs to target different platforms, but for the Editor it has to be 64-bit.</p>
  <p>I think that's a reasonable question and a useful answer, which I have not seen stated elsewhere. I don't think it should be closed.</p>
