16 bit runtime texture issues using UpdateTextureRegions()

[somawheels]

I am using the code bellow to write a 16bit value to a texture.

UTexture2D* tex = UTexture2D::CreateTransient(32, 32, PF_G16);

tex->UpdateResource();

uint8 byte1;
uint8 byte2;

uint8* data = new uint8[32 * 32 * 2];
for (uint32 i = 0; i < 32 * 32; i++) {

int value = 2000;
byte1 = (uint8)value >> 7 >> 1;
byte2 = (uint8)value;
data[i * 2 + 0] = byte1;
data[i * 2 + 1] = byte2;
}

FUpdateTextureRegion2D* region = new FUpdateTextureRegion2D;
region->DestX = 0;
region->DestY = 0;
region->SrcX = 0;
region->SrcY = 0;
region->Width = 32;
region->Height = 32;

tex->UpdateTextureRegions(0, 1, region, 32 * 2, 2, data);

However, when my value goes over 255, the pixel value loops back to 0. I cant get a value any higher than 1.

I have tried a few pixel formats, but to no avail :(.

I need to make texture pixels with 16 bit precision, can anyone help with this?

Update: I fixed my issue by making the pixel data a uint16 array, and casting it to a byte array. like this:

tex->UpdateTextureRegions(0, 1, region, 32 * 2, 2, (uint8*)data);
