Troubleshooting

The most common situations and how to fix them.

Plugin and sign-in

My website password doesn't work in the plugin

If you signed up with Google you don't have a password. Create a token for this computer on the 3ds Max plugin page of your dashboard and paste it into the plugin's Token field. If you signed up with email, make sure there are no spaces before or after your email and password; if needed, reset your password.

"This device's token has been revoked"

The token was revoked from your dashboard. Create a new one on the plugin page and paste it into the plugin.

FCA Farm doesn't appear in the menu

Close and reopen 3ds Max; the menu is built at start-up. If it's still missing, run the installer again with Scripting → Run Script. Details: Plugin installation.

Sending

Send is blocked

Wrong Time Output: in Render Setup → Common → Time Output pick Single and close the window.
No stop limit: set a Noise level (3% recommended), Pass or Time limit in Corona.
V-Ray content: replace V-Ray lights and materials in the scene with Corona equivalents.
3ds Max 2027: save the scene in the 2026 or 2025 format.

Upload takes too long

Large .max files make uploads slower. When the plugin suggests turning on 3ds Max's Compress on Save, accept it; scene files usually shrink by about half, with no effect on the render. Textures uploaded before aren't uploaded again.

Rendering

The job is stuck "queued" or "preparing"

Idle machines sleep and wake up when a job arrives; this can take a few minutes. See the current queue and typical start time on the Farm status page. If nothing moves for more than 15 minutes, open a support ticket with the job number.

The live view stays black for a long time

With heavy scenes Corona prepares the scene before the first pass, and the image stays black meanwhile. Give it a few minutes; don't cancel.

The perspective view was rendered instead of my camera

Make sure you picked the right camera in the send window. Making the same camera your active view and locking View to Render to it reduces the risk. If it still happens with the right settings, open a support ticket with the job number; we're looking into it.

Some surfaces are black or flat in the output

It's usually a missing texture or missing plugin. Check the warnings shown while sending, clean the scene with FCA Farm → FCA Cleaner and send again. If a material that looks right locally still renders wrong on the farm, open a support ticket with the job number and the material name.

I ran out of credits and the render stopped

If your credits run out mid-render, the render is paused. After you top up and restart it on the job page, it starts over from the beginning. Details: Account and credits.

Outputs

No CXR file arrived

Saving CXR isn't working at the moment; a fix is on the way. Jobs without a delivered CXR aren't charged the CXR fee.

Still stuck?

Open a support ticket from your dashboard with the job number, plugin version, 3ds Max version and the error message you saw.
