I train my models on Dreamlook and I have limited experience with this.

The idea was to insert guns into the foreground like a fps. Trainee on about a hundred images with the gun as the focus.

My first test with just abandoned warehouse, lora weight 0.75 produced images with guns in the foreground. Seemed to work instantly. I could potentially make one with triggers for pistols etc but I think it can do that via promoting as is.

We'll see
