If we change the default tile size 32 to 64, the display will be incorrectl.

Hello, @rvargasESRI @whatnick @vsautin1

We tried changingthe default tile size 32 to 64, as follows:
std::vector> grids;
grids.emplace_back(std::move(elevation_data));
build_downsampled_grids(size, grids.front().data(), **64**, grids);
std::reverse(std::begin(grids), std::end(grids));

//
auto writer = create_writer(slpk_file_path);
if (!writer)
return 1;

ENU_to_WGS_transformation transformation({ -123.4583943, 47.6204856 });
i3slib::i3s::Node_id node_id = 0;

if(!process(*writer, size, cell_size, grids, textures, **64**, 128, 0, **64**, { 0, 0 }, 128, { 0, 0 }, node_id, &transformation))
return 1;

Then run the app and get the new slpk , and published it to be a scene service. And, it shows that the scene service display normally in the browser.

Why the exception? Did we miss any other parameter?

Looking forward to your response.

Start by reproducing the scene-service display problem using the shown build_downsampled_grids and process entry points with tile size 64. Compare every tile-size-related argument in those calls and verify the generated SLPK in a browser; done means the 64-sized output displays correctly without the reported exception.
