I am digging the way Sketchup is handling textures and I feel that there is some case were it generates too many textures.
The current test has been made under Sketchup 2017 but it also fails on Sketchup 2019.
Ancre1_2017.skp (474.2 KB)
- Open Ancre1_2017.skp
- Export the mesh to a third party format.
The exported texture folder contains 11 elements.
- Now change the material to one face of the mesh as shown in the capture.
(I use the a brick texture and fill one face with it).
- Export again the mesh to collada.
The texture folders now contains 285 textures : one per faces!
Sketchup internally loses the texture reference and generate under some circumstances too many textures. The problem is shown through the collada export, but I suspect this is a deeper problem as I suspect Sketchup to really have in memory 285 textures images.
Am I right?
