6 months ago Your scene is larger than what Foundry claims to support: 16384 x 16384. And a lot of computers won't go beyond 8192 x 8192. So yes, I expect a performance hit on a scene that big. It is because the UI is being rendered for every pixel on that map. I already cut the resolution of that to 25% of the actual total pixels, but it is still probably a hit.
Foundry v12 is supposed to introduce "regions." I may switch to using those, which are based in polygons and not pixels. I will revisit performance of the UI at that time and see if it is worth refactoring things for speed and features.
Description
The terrain Mapper module introduce a huge CPU usage penalty during terrain layer edition.
The penalty is so high that each added square of a terrain takes up to 10 seconds to register which prevents effective usage for any map work.
Note that the terrain active effects are functional over tokens.
Trigger
Selecting the module's icon in the left side tool menu. Unselecting the tool relieves the performance penalty.
Expectation
Sub-second lag on edition, no performance loss in other areas of the application.
