Why Did My Neural4D Generation Take Longer Than 90 Seconds?

Last updated: September 2026 5 min read

The commonly stated 90-second generation time applies to an untextured base mesh. Texture and PBR are separate processing steps. A complete textured model normally takes more than two minutes, and individual tasks may take longer.

What does the 90-second estimate include?

Output What is processed Typical time
Base mesh Geometry without Texture or PBR maps. About 90 seconds.
Textured model Base mesh plus the selected Texture and PBR processing steps. Normally more than two minutes in total.

The figures are normal estimates, not a deadline for every task. Do not assume that a task failed only because it passed the estimate.

Why can a generation take longer?

Reason Details
Texture and PBR were selected These options add processing after the base mesh.
The input is complex Thin parts, overlapping shapes, deep recesses, or ambiguous depth can require more processing.
The requested mesh is detailed A higher polycount produces a heavier asset.
The service is busy A task may wait before processing begins.

A longer task does not by itself prove that the output will be better or that an error occurred. Check the saved task state before deciding what to do next.

What should you do when a task is still processing?

Step Action
1 Do not submit the same prompt again immediately. Every duplicate submission is a separate task and is charged separately.
2 Open the Assets Library and check whether the asset completed or shows an incomplete state.
3 Open your Account page and review Usage History.
4 Look for the task charge and, if the task failed because of a server-side error, the related Credits Return entry.

Credits are deducted when a task is submitted. Server-side failures are returned automatically. A slow task that is still processing does not create a refund entry until it reaches a failed state.

When should you troubleshoot or contact support?

Use the common generation error guide if the task shows an incomplete state, the result is missing, or the completed asset cannot be opened or downloaded.

If the task remains unresolved or a confirmed server-side failure has no matching Credit return, contact support@neural4d.com or submit the issue through the Feedback page. Include the issue description, your contact information, and screenshots. A Task ID is helpful when available, but it is not required.

Frequently asked questions

Does every model finish in 90 seconds?
No. About 90 seconds is the usual estimate for an untextured base mesh.

How long does a textured model take?
A complete model with Texture and PBR normally takes more than two minutes because those options add separate processing steps.

Should I submit the task again if it is slow?
Check Assets Library and Usage History first. Each new submission is charged separately.

What happens to Credits after a server failure?
Credits are deducted on submission and returned automatically after a server-side failure.
