[Plugin] VariableResolutionChart — runtime-resizable 2D typed grid, pure CPU

Hi all,

I’ve been building a small runtime data structure for UE and just cut the
first release. Sharing it here in case it’s useful to someone.

What it is

A runtime-resizable 2D grid where each cell carries a type tag:
Float, Int32, Bool, Vector2, Vector3, LinearColor, String, Bytes.
Row-major storage, POD cells, no RHI or texture dependency.

Resizing preserves the overlapping region by coordinate. String / Bytes
payloads are stored out-of-line in a sparse map, so grids that only use
numeric types don’t pay for them.

A quick example

UVRCGrid* Grid = UVRCGrid::Create(64, 64, EVRCCellType::Float)
    ->SetRegionType(FIntRect(0,  0,  32, 32), EVRCCellType::LinearColor)
    ->SetRegionType(FIntRect(32, 32, 64, 64), EVRCCellType::Vector3);

Grid->SetFloat(10, 10, 3.14f);
Grid->SetColor(5, 5, FLinearColor::Red);

Also works from Blueprint, and includes SerializeToBytes /
DeserializeFromBytes for saving or transport.

What it isn’t

It’s a CPU container, not a texture replacement. No Virtual Texture, no
Texture2DArray, no GPU path. If you need that, build it on top.
