General / Questions about build tiled model

« on: August 31, 2022, 07:45:38 PM »

Hi
I use metashape 1.8.4 to build a tiled model for an university compus.
The tiled model was perfect when I set the "Tile size" option to 256, but there was many structure and texture errors when I set "Tile size" to 8192.  And the LOD changed form 11 to 3. Pictures in attachment shows their differents.
I think the "Tile size" option means the texture size, and I want to know why does it affect the effect of the tiled model model?
Are there any options can control the real "Tile Size" of the tiled model? For example, the whole tiled model could divided into several tiles of 100 meters X 100 meters.

Thanks.

Bug Reports / Metashape crashed after successful building mesh

« on: January 30, 2019, 11:35:07 AM »

I have a big land survey project include 9860 images captured by fixwing UAV and each image is about 14-20MB.
I use Metashape to process these images with Align photo, Build dense cloud and Build mesh.
After build mesh step and auto save successful, the software crashed. And this project file can not be opened anymore. Every time I open this project, Metashape will stuck and crash after several miniuts. I checked the project folder and find the model PLY file, it is about 9GB. So I edited the doc.xml file in the frame.zip to make metashape do not load the model file. Then the project could be opened again by Metashape.
I have no idea about this situation, but I think there was something wrone about mesh model file. Please help me to solve this problem.
