#### Correctly Packing Jobs for Upload

When preparing your job to be uploaded for render on Concierge, all assets and textures must be packed into the `.blend` file. 

To pack textures and assets into your project, browse to:

![](/files/-MCiAI_-70toJbVnMhLg)

Once `Automatically Pack Into .blend` has been selected, also select `Make All Paths Relative` and save your project. Your project is now ready to upload to Concierge on the `File Manager -> Upload / Launch Renders` page.

If you are using images or videos as a texture you will need to upload these assets in a folder with your blend.

{% endhint %}

**Cost Estimates**

When running a `Preview` frame on Concierge Render, the cost estimate will be more accurate for more complex scenes. If your render time is very short, the cost estimate will be over-estimated, in some cases severely. While the `Preview` feature is great for checking your work along the way, we suggest running a single frame at full resolution before submitting your finished job to get the most accurate estimate.

#### Render Artifacts

All artifacts (meaning layers and node output) are generated and delivered in your job output folder automatically. If you do not want/require these, please disable them in your .blend file locally before uploading.

{% hint style="info" %}
The output of multiple artifacts does not increase the cost of your renders.
