  i hava email my tileset.json, In b3dm.rar have sub jsons and b3dm. can you receive that?

  thank you. This problem has plagued me for a long time.  this is root data.![32EF580B@8D47C34D.A5402F5A.png|357x211](upload://939ZtkPMvZWfLZjhZtEILRmX4K6.png)when i room in, the data changes the position and the height is not right.

The appendage is the original data and the result data.

I think it may be that the two parameters of geometryError and region are problematic. And I don’t know how geometricError calculates.

thank you very much.

The b3dm.rar is probably too big to be attached to the email. Can you try uploading it to Google Drive or something similar?

Sean Lilley, do you download the data of b3dm.rar and daedata.rar?

Ok the new link works - I will download the data tomorrow and check it out.

The tileset seems to be ok. It looks like the problem is the glTFs. Every glTF except the two root tiles has an extra transform applied to it. For example I see that Tile_+055_+039_L16_0.b3dm has a translation of (-1056.09, -461.411, -43.6774, 1) applied to it. I attached some screenshots of the node hierarchy for Tile_+055_+039.b3dm and Tile_+055_+039_L16_0.b3dm. Hopefully that helps with debugging the problem.

Sean Lilley:

thank you for your help. i fixed the .dae files,and then i have solved the problem that the files of .b3dm can not see.

i have another problem now, I use near 2GB data to do the test, Chrome browser browsing speed is not very fast, memory consumption is about 300MB, and fireFox memory consumption is about 1GB. How can we optimize browsing speed and reduce memory? Is it better to set the geometricError parameter? do you have a method or tool to calculate the geometricError?

thank you very much!
