Once you have all of that, there are lots of tutorials and forum posts that will help you along! (Sims4Studio offers their program as well as a helpdesk) It takes lots of practice and patience. You will also need Sims4Studio and Blender to recolor, retexture and edit meshes. To start, make sure you have a 2D editing program such as Photoshop or Gimp. Take a look at my Terms of Use. Everything you need to know is right there.
Although, if I do receive requests, I’ll consider doing them if I like the idea. I’ll end up deleting WCIFs from my inbox, so do not be surprised if you don’t receive a reply! Although, if a WCIF is sent off anon, i’ll most likely answer privately. Almost everything I use can be found below in my Resources, CC Finds Blog or through Google. A full list of specs and product info can be found here. I use an MSI VR Ready GE72VR Apache Pro-009.
What computer do you use/what are your specs?
