I am buying good 3d animations which look great. Your 3d animation should look good and also should have the sourcefiles in 3d Max as well as a document how the task was completed in animation process step by step.
Your 3d animation should cover these areas
Use 3d Max software
Develop the scene using available tools and geomatric objects
Visualized scene using different camera views
create lights effects to different terms
render scene in preferable format
Edited using a suitable video editing software
add sound to the final output
I will need 3d max source file or adobe aftereffects, premire source files!
If you have a ready made scene just sell me. I dont have much budget for this actually since I am just starting my own 3d site yet.
