Useful Collection of Public Domain, Creative Commons, Free sounds and graphics for commercial use

As an Indie developer i required lot of free sound, music and game art for commercial use. Internet is huge but it still lacks resources with permissible license. Looking for free stuff is not bad but also not great because every work has value and in real life there is no free meal. There are very helping people who offer their work for free to ease development work of indie workers. Below are links to such useful assets.



opengameart.org

http://www.opengameart.org

A website with lots of free multimedia resources. Contains 2D, 3D, music, sound etc stuff with search and page wise browsing. It includes resources with multiple types of open licenses.

"We've created over 35,000 images, audio files and 3D models for you to use in your projects. Thanks to our public domain license you're even allowed to use them in commercial projects!"

220+MB of arts and sounds.




Glitch Game Art

https://www.glitchthegame.com/public-domain-game-art/

"The collaborative, web-based, massively multiplayer game Glitch began its initial private testing in 2009, opened to the public in 2010, and was shut down in 2012. It was played by more than 150,000 people and was widely hailed for its original and highly creative visual style.

The entire library of art assets from the game, has been made freely available, dedicated to the public domain. Code from the game client is included to help developers work with the assets. All of it can be downloaded and used by anyone, for any purpose. (But: use it for good.)"


Huge collection of arts. Don't miss it!

https://github.com/saniv/free-game-art

Very good collection of collections!. This is a MUST visit page. However the repository is big and sometimes you might want to download only few folders from github. For example we want to download a CC0 or non GPL licensed assets. If you know how to use command line then a single folder can be exported from github. GUI based software can also do that.

For example you want to download https://github.com/saniv/free-game-art-unsorted/tree/master/oblique/DCGames_stuff folder but there is no option on that page. Start command shell like bash on Linux or cmd.exe on Windows. Install SVN subversion software and run this command -


Firstly copy the link

https://github.com/saniv/free-game-art-unsorted/tree/master/oblique/DCGames_stuff

Then replace tree/master by trunk. It becomes like this -

https://github.com/saniv/free-game-art-unsorted/trunk/oblique/DCGames_stuff


Now run

svn export https://github.com/saniv/free-game-art-unsorted/trunk/oblique/DCGames_stuff

This will download only the DCGames_stuff folder. If you don't like command line then try a GUI software like TortoiseSVN and export the url above as example.

The files are very big and i have compressed them to very low size still maintaining quality. Due to their license restriction i cannot share those compressed ogg files. Please visit their site and download them all. Many of these audio have 96KHz sample rate. Do read the download resume technique at end of this article to download from this site because the big files many times stop resuming.



https://www.freesound.org/

Various licenses and huge collection of user submitted sounds.


www.pacdv.com/sounds/

Another good site i used.
Search "free sounds" on Google. There are many sites like this.





Get sound samples from sound pack formats

One best way to get sounds is packed, synth sound formats. Sound formats like SoundFont SF2, Downloadable Sound DLS, Patch (pat files). There are many sites which offer these files. Below are some valuable sound collections or packs.

"The Metropolitan Museum of Art makes 375,000 images of public domain art freely available under Creative Commons Zero"

As it says huge collection of museum art can be used for even commercial purpose. Deriving these arts to make new things can be very useful.




How to get more multimedia assets with lesser effort?


I spent lot time in learning programming, music, sound effects, digital arts and some more skills. Now i can make games alone. However i realized one must rather invest time in one skill they love most and Master that skill ( I love all but music is at top :) ). What about those technologies where skill is not enough to complete a work faster? There are many ways to do it. You can pay to a freelancer and get your work done. What if you don't have much money?. This is where free stuff comes to help. Some very useful links have been shared above. But now i will share techniques to get free stuff with little effort.

A video is a sequence of pictures. Therefore an open licensed movie is also bundle of same license image assets. With this idea i downloaded open source videos like BigBuckBunny. ElephantsDream, Sintel etc. There are lots of effects, textures, sounds etc in these videos. Extract data from these videos and use them wherever needed. But don't forget to follow the license honestly!.


Here are links of some public domain, Creative Commons videos:

https://en.wikipedia.org/wiki/List_of_open-source_films


WARNING:


There are many resources which are public domain but can still cause copyright issues. For example old SuperMan cartoons are public domain but the SuperMan himself is not!. Please be careful for these type of things.






How to resume downloads which expires if stopped?

Many websites generate download links which expire after some time or fail if multiple connections are created. I use UGET on linux. Windows version of this software is also available. Simply add a URL and start downloading. When a new url is created go to properties of the download item and replace the old url by new url. Another way is to use KGET. Its also a Linux app. It can add mirror links. Add whenever a new link is created.

The links shared here can be very helpful to many indie and non-indie developers. Please submit links in comments i will add here.

BVHUtil - A multi-platform BVH MoCap utility (Like BVH Hacker)


Update 28-Feb-2017:

Due to lack of fund, time and reason i quit gaming this project was suspended. However even after ~1.5yrs no BVH viewer on android exists. I thought someone might make one. So may be i will try to re-build a simple bvh viewer to keep an option for some users. The download link to PlayStore is dead because i disabled the BVH Viewer app but many apk sites maintain a copy of it. Please download from these sites. I will update link if i could.




I am working on 3d games like Tekken 3, Dear Or Alive using unity3d and some other engines/libraries. Soon i started working got stuck in making models and their animations. While making 2d games i could make graphics alone but in this case its way more harder and time consuming. I make human models using OpenSource software MakeHuman and then import them into Blender 3D to do rest of work. However there is a method called Animation Re-targeting which can use external animation to be applied to acompatible model. A compatible model means they must have same skeletal architecture no matter what design of mesh they have. Fortunately one can use BVH MoCap files. Many of them are freely downloadable. Carnegie-Mellon Graphics Lab Motion Capture Database offers lots of free BVH files.



There is already an editor called BVH Hacker which can do most of tasks anyone needs. However i tried to find, as much as i can, a software which can edit REST POSE of BVH file without affecting the motion data. I could not find any & there were methods which were time consuming and not for anyone who doesn't know how to use Blender3D. So i made Rest Pose editor* myself and it works well.


Details:
However i am using it for personal use and willing to release it on stores. At present BVHUtil works on its own format which is nothing but extension of BVH replacing Euler rotations channels by Quaternion.


Features:
- BVH viewer with interpolation of animation.


WIP features for updates to come:
- Frame control for viewing. View any frame like seeking a video frame.
- Remove frames
- Edit Frame animation data i.e. rotation of joints/bones.
- Export* interpolated frames to enhance animation smoothness within file.
- Export* any part of skeleton. E.g. export right hand as bvh.
- Edit rest pose* without affecting a single animation frame. This feature is rare and i will take some time to make it available. This feature is complete and ready but is not exposed in UI. More info at bottom.
- Animation re-targeting to embed animation in a model? I myself need this and will make it anyhow.


* mark is for features which are available in my own BVH2 format. This is extension of bvh format where Euler rotations are replaced by Quaternions. Once i make precise port of these features to bvh format i will update this app. * features will be available once i finish BVH2 to BVH export. BVH2 format name can probably be changed with something else.


Download:
I have only released Android version yet. PC version will be released after i am done with mobile builds.
