If I participate in a short animation video contest, can i use the unity software to produce the animated video by using a asset and scene of unity ?
Are you asking how to make animations in Unity? Because you can just put a camera in a scene and record the animation.
If you mean legally can you use Unity to make animations, Yes, Unity encourages anything from animations to Films
Don’t sure about Unity. If you really need nice animation with all the contemporary standards, use the Animation Video Boom - Wow-How Studio - Video Production, 2D & 3D Animation . We buy your Youtube and advertising video only on the resource. the team is very nice, they work fast and everything goes well. But it would be interesting to hear about other teams and resources if you have some experience with them.
