How to make custom gun visible in first person?
My custom gun model does not show in first person, the shadow of it shows on the ground, but i can't see the model. In third person it shows the model and its shadows and it is on the ground. Can you please share your models and/or tell me the minimum requirements to make it visible in first person and positioned in the hand?
Thank you
