Based on the following bounty request https://civitai.com/bounties/491/lora-for-my-jeep-camo.
Unfortunately due to the very limited amount of images , and the fact that they are all in the same setting, this model is not very flexible.
If you want to try to change the background you will have to crank up the CFG, quite a bit.
Get decent results from weight 0.5 -0.8. obviously the lower the weight the more flexible it becomes, but more details you will lose from the original jeep.
