Black texture when texturing imported model
« on: February 08, 2023, 05:05:31 AM »

We are trying to texture an imported model in Metashape.

We import a PLY model using
Code: [Select]
chunk.importModel(transformed_filename, Metashape.ModelFormat.ModelFormatPLY)
We texture it using

Code: [Select]
chunk.buildUV(mapping_mode=Metashape.GenericMapping, page_count=1, texture_size = config.DEFAULT_TEX_SIZE*2)
chunk.buildTexture(blending_mode=Metashape.MosaicBlending, texture_size = config.DEFAULT_TEX_SIZE*2)

But the result is a dark gray color (there doesn't seem to be any error from Metashape's output)

Here, the DEFAULT_TEX_SIZE is 4096
The model has 56148 vertices and 112360 faces.

The model is correctly positioned in space it doesn't seem to be a positioning problem. Any clue on what's the problem here?

Hello sergio,

Can you please show the same model in Solid view mode? Also please check, if the texturing goes fine when you generate a rough model from the tie points (based on camera alignment)?
