Contribution Guidelines

How Best to Present Your Work

It’s natural that when you make a contribution to the RenderMan Community you want it to look as good as possible. By following these official guidelines, you can create high-quality posts using our official templates and stylistic conventions described below. 

What Can I Contribute?

There are three main categories for contributions: showcases, resources, and tutorials. You’ll want to pick one of these as a primary category:


Here is where you can post your best work and get feedback. Appropriate content would be final renders, case studies, and works in progress. A Showcase can feature images and/or movies. 


Share your assets with the rest of the community. These assets can include shaders, scripts, textures, rigs, scene setups, and other useful materials.


Share your knowledge and build a tutorial for the RenderMan community. Emed a video or build an article. Your choice.

Note it is possible to select multiple categories. For instance, a shader tutorial might have a shader attached as a resource, and could be eligible for both categories. However, a conservative approach to assigning multiple categories is prudent.

Posting Content

Cover Images

When you submit a contribution you’ll want to choose a good cover image to be used as a thumbnail. Notice that two aspect ratios are used for thumbnails on the community site, 1:1 for Resources, and 16:9 for everything else. Please note that when you add a cover image you can select how the image will be framed for both ratios, 1:1 and 16:9.


The RenderMan Community supports video directly from Vimeo or YouTube. Simply copy the URL for your video (you must first upload it to Vimeo or YouTube) and then past the URL into the appropriate field. We recommend posting videos in HD format, either 720p or 1080p, with an aspect ratio of 16:9.

Maximum Image Size

The maximum size of images is 15MB, primarily to optimize thumbnail generation. For very large images (such as HDRI’s) you may include these as compressed archives.

Maximum File Size

To support complex datasets, individual files sizes are supported up to one gig in size. Multiple files may be added to any contribution, and multiple files may exceed one gig. Keep in mind when uploading large datasets, several smaller archives can be easier to download than one enormous attachment.

Styling Content

Styling a Showcase

You may submit both images and/or videos as showcases, and you have a lot of flexibility on how those images are presented. 

Styling a Resource

For resources there are a few standardized templates to help you post content that is stylistically consistent. Here are the currently available templates:

The Official RenderMan Swatch

Styling a Tutorial

We encourage users to post videos in HD format (either 720p or 1080p) for stylistic consistency, use our official templates to give your video the RenderMan Community look. Here are the currently available templates:

Packaging Assets for a Contriubtion

 When uploading assets (other than images or video) include the following in a compressed archive:

1) Your Resource - The asset(s) you wish to share, which can be shaders, scene files etc. 
2) Cover Image - A swatch of your resource. A shader should use the The Official RenderMan Swatch. 
3) README (optional) - A text file with any additional infomation on use, copyright, attribtution, etc.

Maya Materials may also include a swatch for display in the hypershade:


Keep in mind that assets may accompany Resources, Tutorials, and Showcases.

Moderation & Approval

Once you upload a contribution, it will be placed into a queue for approval by one of our community moderators. Once approved, your content will be available for viewing on the site. While we strive to approve content immediately, it may take several business days to approve new contributions.

Exceptional contributors to the community earn the ability to post without waiting for moderation, and may ultimately be promoted to moderator status.


Showcases & Tutorials – For showcases and tutorials, by default you retain ownership under the following Creative Commons license, which offers a high degree of protection including attribution, non-commercial use, and no derivative works.

Resources – By default resources are posted in the public domain. We encourage users to post resources in the public domain because it make sharing assets much easier. By uploading content as a resource, unless you stipulate otherwise your work (such as a shading network) enters into the public domain.

Stipulate Your Own License – If you'd like to share your work, but wish to explicitly set your rights to the content, create your own a Creative Commons license. Licensing a work is as simple as selecting which of the six licenses best meets your goals, and then marking your work in some way so that others know that you have chosen to release the work under the terms of that license. For a Contribution to the RenderMan Community, you may add the license to your post, and include it as a README in your downloadable assets. 

The Creative Commons License-Choosing Tool can help you select the right license.
