I use as texture for DEM image with original resolution 4000x4000px. But when qgis2threejs creating 3D model in browser - texture looks like image with low quality. In plugin menu there is line "resolution"

enter image description here when i choose 200% or 400% quality are not changing. How to do better quality of texture?

Under resampling not display. Check plugin documentation: https://qgis2threejs.readthedocs.io/en/docs-release/ExportSettings.html

  • in documentation is written that: "If map canvas image is selected as the display type, texture image size for each block is maximum 256 x 256". It turns out that to get a texture of 512x512 need to divide the DEM into 4 parts? – Jonny Apr 3 '18 at 12:10

Instead of creating a large image and using it as a texture, you can divide whole model into blocks and assign images to each block. Try the "Surroundings" option.

  • if i try the "Surroundings" option the option "Clip DEM by polygon "is not active. It is important to me - it well limits the size of my model. And I did not notice that the quality of the textures is changing – Jonny Apr 3 '18 at 12:06
