I only want the bicep muscles to contract and light up but other muscles are lighting up. How do I get only the bicep muscle to light up when it is being contracted?

Thanks for pointing out this limitation.

I ran eight different generations, tweaking the prompt with precise descriptions and switching models, but none produced the result you requested. The closest outcome was a bicep muscle contraction shown through elbow flexion.

My assumption is that the models currently interpret “bicep contraction” as the functional movement of elbow flexion, and don’t yet distinguish between muscle fibers tightening without joint movement versus movement at the joint.

For now, we can confirm that there’s nothing wrong with your wording. The best next step is to submit your feedback by clicking the thumbs‑down icon hat appears when you hover over the image and submit your feedback, which will help the team understand and improve this behavior.

Thanks again.

The system should understand how muscles work over bones to make a contraction in all areas of the body.
Right now, the system, when asked the create a video showing scapular retraction on a muscular level as an illustration showed no movement. it only blew up the associated muscles like ballons to represent the movement. the shoulder blades never came together.

Hi Bromwell,

Thank you for bringing this to our attention.

As you can see in this thread, this looks like the models don’t yet capture the complex relationship between muscles, bones, and movement across different areas of the body.

The best next step is to submit your feedback by clicking the thumbs‑down icon that appears when you hover over the image and providing details. This will help the product team better understand the issue and improve how muscular actions are illustrated.

Thanks for sharing this.
