This is an assortment of changes to all the spiders in the game.
It changes all the spider models in the game into big rocks. It also replaces the spider sounds with silence or rock sounds.
This should affect every spider in the base game, including Ranger summons and the Shapeshifter's spider form.

A lot of the spider replacers on the nexus which swap the spider out for different animals are unstable, so this is an attempt to get around the issue with a purely model based solution. I don't hate spiders but a lot of people do, and also it's funny to see a rock bouncing around the place.
This mod does contain some GDAs to replace sound and other things, but all the folders are independent. So if you get into difficulty you can just delete them and keep the models/textures folder. Or if you like the spiders original model but want to stop them hissing, you can delete the mesh and texture folder and keep the rest.

What it does
Replaces LOD0,2,3 spider models and textures with a low poly rock
Replaces the spider corpse with rocks (this is hard to test though so let me know if it works)
Edit the footfall noises so they are silent instead of a scuttling noise.
Removes the hissing noises from the spiders.
Removes blood pool from the spiders.
New non spider portraits for the Ranger summon and Shapeshifter form

What it doesn't do
Change any of the spider's attacks or animations.
Change any icons or text to remove the word spider
This may or may not change spiders added in fanmade modules, depending on if they are unique models.

Installation
Unzip and place folder into your My Documents\Bioware\Dragon Age\packages\core\override folder.
To uninstall just delete the folder, it will go back to how the regular spiders look.

If you have anything editing the footfall .gda it will be incompatible with these GDA and you'll have to choose one or the other.
