we listed all frequently asked questions regarding our render farm in our FAQ.

What is iRender Cloud?

iRender Cloud is a software as a service (SaaS) which allows you to submit and render scenes with render cloud. You can concentrate on designing and creating your scene, and iRender Cloud will take care of installing and maintaining everything necessary to render scenes, without hogging your hardware and software. It is available for all 3D platforms. iRender Cloud supports and renders scenes using both the CPU and the GPU engines.

Rendering in iRender Cloud is pretty simple and straightforward. All that is required is to have the iRender Cloud Client application installed, after which you can submit jobs to iRender Cloud. Once in the cloud, you are able to monitor the progress of your currently submitted jobs, queue up subsequent jobs, as well as change job settings and resubmit jobs …

What is render farm / render cloud / cloud rendering ?

A render farm is a high performance computer system, consisting of many powerful hardware components, which provides a user with a lot of computing power to realize 3D projects. The focus of the service is on high quality and extremely fast rendering.

A render cloud is a commercial render farm. As the word “cloud” came into fashion for internet service providers, the expression “render cloud” became very popular as well. The words “Render Farm”, “Render Service”, “Cloud Rendering” and “Render Cloud” are synonyms for the same offer – an online rendering service.

why do i have negative iRender Points?

If you run out of iRender Points during the rendering process, we pause your job but let all active PCs finish the frame they are currently rendering. It doesn’t make sense to stop an image rendering on the render farm which is nearly completed. Once you buy new iRenderPoints and your balance is not negative anymore, you are able to download your images.

Imagine the very worst case: your image is 99% finished and your iRenderPoints run out. If we stop rendering immediately you lose your render, all iRenderPoints and a lot of time! That’s why we carry on rendering and you might get negative iRenderPoints.

As soon as you make a payment to get to at least 0 iRenderPoints, you will be able to download your rendered frames.

What type of render jobs are supported by iRender Cloud?

iRender Cloud supports rendering still images and animations.

How do I start a render job?

To start a render job, submit a scene through the iRender client app. If there are free resources in the cloud, iRender Cloud will start rendering your job. If there are no free resources, your job will join a queue and will start rendering automatically when resources become available.

What image types will I get as an output by rendering in iRender Cloud?

The output image types you will be able to download by rendering in iRender Cloud are JPG and the file type you have specified in your scene’s settings. These settings are customized in the 3D application you use for designing your scene. If you don’t specify anything in the 3D application, iRender Cloud will generate an EXR image beside the JPG.

How can I update the iRender Cloud client app?

When a new version of the Chaos Cloud client app is available, a notification appears. Click on it and update the client app.

Will you notify me when my job is completed?

Yes. By default, our notification service will send you an email if your job status changes from one of the active states to one of the two final states: “Completed” or “Failed”.

How secure is iRender Cloud?

All communication between the user and our services is encrypted, so your data is safe. Files and other data that go into iRender Cloud are attributed to the user who submitted them, making accidental sharing impossible.

Will you notify me when my job is completed?

Yes. By default, our notification service will send you an email if your job status changes from one of the active states to one of the two final states: “Completed” or “Failed”.

Technical Issues

Why are there black spots on my render output image?

If your job has dark spots where you expect to have objects, it might be because you are trying to render a scene with plugins which are not supported by iRender. Don’t worry, our technicians can help you.

Why is my render output image black?

If your image is black, it might be you are using a camera directed in a position opposite your scene.

My job status is staying at ( Preparing ), and will not start rendering. Why is this?

It may take up to three minutes to setup and start a rendering machine. If it fails, the job state will change to “Failed” and we will notify you.

If one frame from my animation job fails, will the whole animation job fail?

If more than 5% of the animation frames fail, the whole animation job will be stopped and considered as failed. If the number of frames is too small, than at least two frames have to fail to fail the whole job. You will still be able to download the output generated up until the fail of the animation job.

Can I resubmit a job which I have already rendered in iRender Cloud?

Yes, you can re-submit a job with the Edit option, which is located in your List Job tab.

Why does exporting a scene take so long?

If you are re-submitting an animation scene that has a change in a character or geometry, the whole export process of a scene is done again. This process might take up to tens of hours depending on the complexity and number of frames in the animation.

Some scenes that are rich in geometry or some long animations could also take long during the exporting process. Note that the exporting process and the rendering in iRender Cloud are two different things and you are not charged with credits during the export.
