Trying to get omnimattezero installed but cant find the models

HI, Not sure if you can help, but I got it working, but it renders a faint grid over everything, i tried to set the block count to zero to avoid tiling but it didnt work, is there any way to prevent this? i know this is for 12GB cards but I have 32GB so maybe I can skip the tiling somehow but it wont let me for some reason? How can I disable group offloading?
