Error message

views

What it means

The params-array overload of SetOutput throws ArgumentNullException("views") when the caller passes a null array. Unlike the single-texture overload, it does not reject an empty array here — only a null array reference triggers this error.

Solutions

1. Initialize the Texture[] array before calling SetOutput
2. Pass at least one texture to the params overload
3. Guard: if (views == null) return;

Example fix

// before
Texture[] outputs = null;
effect.SetOutput(outputs);
// after
Texture[] outputs = new Texture[] { renderTarget };
effect.SetOutput(outputs);

if (views == null || views.Length == 0) throw new InvalidOperationException("At least one output texture required");

bool IsValidOutputs(Texture[] views) => views != null && views.All(v => v != null);

try { effect.SetOutput(views); } catch (ArgumentNullException) { /* supply initialized array */ }

When it happens

Trigger: Calling effect.SetOutput() with an explicitly null Texture[] (note: effect.SetOutput() with zero arguments passes an empty array, not null, and does NOT throw this).

Common situations: Storing output views in a field initialized later, then invoking SetOutput(views) with the still-null field in C#; passing an expression that evaluates to null due to a failed texture array allocation.
