How Can I change the amount of souls that it takes to fill one. I want my soul chest to be 100 souls.

It's based on how long it takes to grow to max size. You need to edit the following lines in the growing_soulbox.gsc

	level.grow_soul_start_scale = 1;

I reckon leaving it at one is fine unless it's a different size in radiant.

	level.grow_soul_size = 2;

Make this how big you want the model to grow (if it's not growing then two is a good number to work with)

	level.grow_soul_growth = 0.1;

This determines how many zombies need to die to fill the soul chest. The 0.1 means that the model scale increases by 0.1 every time a zombie dies near it. This occurs until the scale reaches that defined above. In this example it would take 100 zombies as (2-1)/0.1 = 100

Have you got a reflection probe in the room you took the picture from? If not chuck one in and make sure it covers the whole room and nothing else.

I've managed to get the perk machines to randomise like in DR and SoE and I've managed to get the lights to turn on when the power is turned on, however the lighting depends on where the machine prefab is placed in radiant. Does anyone know how I can get perk lighting to accompany the randomised perks?
