RaysRender under the hood

1. What is this service about?

The service is about CGI rendering. It allows users to render Blender files using Cycles engine on hundreds and thousands of GPUs.

2. How can I use the service?

You must register with email or social network account, upload your project file (.blend or .zip with your blend project files), select options for rendering, prepay rendering with the calculated price and download rendered frames as one zip-file. It’s simple :)

The unique feature of the service is that simplicity and speed. You don’t have to manually setup hundreds of workers and orchestrate them, this is done automatically.

3. What hardware is used?

The minimal node hardware is 6x NVidia Geforce 1080 Ti GPUs, 32 GB RAM, Intel i5 CPU, 120 GB SSD.

4. How can I contact support team?

Use online assistant or https://t.me/RaysRender Telegram chat or [email protected].

Prepare sources

5. What Blender versions are supported?

We support these blender versions: 2.79, 2.83, 2.93. If you need some specific version, feel free to message us.

6. What are the limits for source files?

At the moment the maximum file size is 2.5 GB for direct upload and 10 GB for upload via Google Drive. This limit can be increased, stay tuned.

Your rendering frames should fit NVidia GeForce 1080 Ti and 32 GB system RAM to be rendered.

7. Which resolutions are supported?

We support up to 20 000 x 20 000 images.

8. Which output file formats are supported?

All image output formats are supported, video output formats are not supported. You will get results in format you've set in Blender settings, so check that you didn't setup video output format before uploading Blender project files.

9. Do you support Blender plugins?

At the moment no plugins are supported. The official plugins distributed with Blender will be supported soon, stay tuned.

10. Do you support Eevee for Blender?

No. Eevee has known limitations, that makes no sense of using this engine on our render farm:

  • No multiple GPU rendering. Eevee will use the graphic card used by the rest of Blender's UI.
  • Headless systems (without a display) are not supported currently. Background rendering when there is a display is supported. ( from Blender wiki )

Besides, Eevee is real-time engine and is used for fast previewing of frames. Why should artists use remote render farm for it? Render farm will never be as fast as realtime engine.

11. How shall I prepare my project files for uploading?

Ensure that you’ve chosen Cycles engine and set up your scene and object properties for Cycles. Be careful with render border settings - service will use them to render. Anyway check previews to ensure you will render what you expect.

If you can pack all project data in one .blend file, than do it! Use File -> External data -> Pack all into blend.

blend file packing.

Or else you need to prepare zip file with all your projects data, including directory structure. Please make sure all your paths in blend file are relative.

12. How to properly pack external resources?

To correctly render your model with external resources, you should:

  1. place your blend file(s) and all resources (textures, movieclips, and so on) in one folder (you can use subfolders if you want)
  2. in blend file(s) make all links to external resources relative
  3. pack all content from that folder to zip file.

Then you ready to upload your zip to rays render. Note about upload limits.

13. Do you support baking physics, smoke, fire, textures, etc?

The service will not do baking automatically. But you can bake your physics on your PC and upload project zip file which includes physics (see also about packing external resources question). Note about upload limits.


14. What is the price?

The price is 0.004 USD per OBh (OctaneBench-hour).

This is roughly equal to 0.5 USD/hour on Nvidia GeForce 1070 and 0.75 USD/hour on NVidia GeForce 1080Ti.

The minimum price of one frame is 0.02 USD. The minimum price of one task is 0 USD

15. How the service is payed?

Each and every rendering job is charged separately. The price for the job is fixed beforehand and the job is 100% prepayed.

You can pay with credit card. The minimum credit card payment is 1 USD. If your task's cost is lower, extra money will be refunded as bonus points.

You can also pay with bonus points. Bonus points are awarded for early adopters and referral program participants.

Also if you stop and delete incomplete job, or your job will complete with faild frames, you will be refunded with bonus points for the frames that were not processed.

16. Can I get USD for my bonus points?

No, you can only spend bonuses for new render jobs at our service.

17. What is analysing about?

Analysing is the process of fast rendering your file with low quality in order to estimate the final price for rendering.

Rays cuts off the risk of overspending the customer’s budget. The rendering price is fixed before rendering starts and will never change. To be able to offer customer this fixed price we have to run this analysing process. It’s more than 100x times faster than real rendering and it’s completely free of charge.

This cutting edge feature guarantees that you will get the expected results within a predefined budget. No more “deposit” extra “tokens” to be sure that you will finish your job! No more payments for “test” runs in order to estimate the budget yourself! This is a unique feature of our service.

18. I expected rendering costs at X, but analysis show me Y

Cost estimating is a complex process. The final price depends on both scene complexity and network load, so it can vary. Just like Uber :)

19. Can I stop the job before it is complete? For example, I noticed some errors in source .blend file.

Yes you can. You can pause and continue the job at any moment, note that all processing frames will not be stopped immediately, but will be finished. When you delete the incomplete job, you will receive a “cacheback” with bonuses for not rendered frames.

Getting results

20. How can I download rendered images?

After the job is complete you can download all rendered frames in one zip file. You can also download image files one-by-one as soon as they are rendered.

21. Can I view rendered images before the job is complete?

Yes, as soon as frame image is rendered, it becomes available for you both as a low resolution preview on web, and a downloadable full quality image file.
