Re: [Therion] Calibrating surface map

2024-02-20 Thread Xavier Robert 
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

Re: [Therion] Calibrating surface map

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
