Lots of grass in objects / Raycasting not working

[eggdropsoap]

Grass is generating inside objects.

Versions:

• NGIO NG: 1.0.8 AE
• Skyrim.exe: 1.6.640

Issue description

I have already generated a throwaway grass cache successfully as a test, and then removed it. I'm now trying to properly configure my grass before generating a real grass cache, but I can't get grass to stop generating in objects.

NGIO NG is running. I am not using cached grass while I tune the raycasting, but the raycasting settings seem to do nothing and no grass is being removed from under/inside objects.

skse64.log shows NGIO NG is running:

loading plugin "NGIO-NG"
registering plugin listener for SKSE at 50 of 107
plugin NGIO-NG.dll (00000001 NGIO-NG 01000000) loaded correctly (handle 50)

I'm using Seasons of Skyrim, Seasonal Landscapes, and Landscape Fixes for Grass Mods.

I also tested with seasons turned off (Season Type = 0 in po3_SeasonsOfSkyrim.ini) and Landscape Fixes for Grass Mods disabled, and the grass generation in/under objects was much more obvious and worse.

This screenshot taken at the ruined house west of Whiterun (Tamriel cells -2,-3 / -2,-2) with Seasons set to 0 and Landscape Fixes disabled as above shows the generation and clipping problem clearly:

Raycasting has an issue when not used with a cache of not applying on the first loading of a save. Try saving at the location and reloading the save twice to see if it takes affect.

That does work!

Good to know. Not ideal, but that workaround will let me test my grass setup before generating the grass cache. And really, that's all I need. Thanks!

Glad I could help. I'll make sure to update the readme some people know.
