Are you really just a PhD student?
Yes, I just get bored and start learning things like this.
What software do you use?
Blender ( blender.org ), that’s the program that I use for everything. From modelling and rendering to video editing and sound mixing. It’s and open source program and free to use in anyway and for any purpose.
Do you have customer service?
Of course! There on the right side there should be an email. If you want to contact me, that’s probably the easiest way.
