Hi all, I have a similar behavior, for some of my huge lox files, the map texture does not show on the DEM when loaded. But if I push the Ω-button « entrances », the overlay loads. They open OK with Caveview. If it is needed to find the bug, I am running Therion and Loch on a MacOS 12.6.9, and I have installed Therion and Loch from sources: $ therion --version therion 6.1.7+dev (compiled on 2023-06-02) - using Proj 9.3.1, compiled against 9.2.1 Loch version 6.1.7 (compiled on 2023-06-02) Cheers Xavier

Hello Jonny,
Thanks for the hint!
I’ve tried to open few old models which were surely working and half of them did not show any map texture.
Trying to open the same models on other computer proved that they all work fine. There must be something wrong with graphics on my laptop. Will try updating drivers etc.
Cheers, Andrey

Hello Andrey,
Are you able to see _any_ bitmap overlays in other loch models? I had an issue long ago where an issue with my video card caused textures to load incorrectly or not at all.
Also, in the scene settings options in loch, do you have it set to actually show the bitmap overlay?
Cheers, Jonny

I am struggling to make a 3D model with terrain overlaid by a raster map.
Everything is done according to the Thbook however Loch is only showing me a semi-transparent grid without any map overlay.
Here is what I put into my Surface.th file:

If I comment ‘bitmap’ line the .lox file will be a lot smaller and vice versa if uncommented so I assume that overlay is being written into .lox
Could this be due to the .jpg file size which is 10.5Mb?
I was able to make 3D models with terrain overlay in the past but image size was under 10Mb.
Many thanks, Andrey
