Making your own muscle
- The prompt box opens with
muscle, cinematic light, ultra detailed, 18+in it. Rewrite as much of that line as you like - the wording is a starting point, not a form. - Decide between a still and a clip. Stills come back in seconds; a clip takes about a minute and runs a few seconds, which is the length the motion model was trained on.
- Attach a reference frame if the face or the body has to be a particular one. Leave it empty and both get invented.
- Keep the result private or put it in the gallery - neither costs extra.
Groups, not the word muscle
The single word pulls one specific look out of the model: stage tan, oiled skin, arms held wide, competition backdrop. If that is not what you want, the fix is to name structures instead of the category. wide lat spread, separated quadriceps, deltoid split visible gives the render targets it can shade, and it stops reaching for the posing dais. The category word is worth keeping only when you actually want the stage look, and then it does the whole job on its own. Otherwise treat it as a label that costs you control over tan, backdrop and pose at once.
Vascularity is where it falls apart
Ask for veins and at ordinary resolution you get scribbles: thin dark lines wandering across the forearm with no relationship to the muscle beneath, sometimes crossing each other. The render has no vascular map, only a texture memory. Keep it coarse and local - one raised vein along the biceps, none on the abdomen - and put the detail where the frame is largest. A tight crop on an arm can carry veins; a full-length frame cannot, and asking anyway produces noise across the skin. The same ceiling applies to skin detail generally: pores and fine hair read at close range and turn into grain further out.
What to write in what order
- Named group first:
heavy shoulders and back, moderate legs. - Then light:
hard light raking from the side, deep shadow between groups. - Then skin:
dry skin, no oil, natural toneif you want out of the stage look. - Vein detail last and small, or not at all above waist-up framing.
How this differs from fitness and athletic prompts
A fitness request wants definition at moderate size and is solved mainly by light. An athletic request wants a body shaped by a sport, which means uneven development - thick thighs, ordinary arms. This one is about mass, and mass has a specific artifact: bilateral mismatch. Left and right arms come back different sizes because each side of the outline is generated without checking the other. It shows most in symmetric front-facing poses, which is exactly the pose the word invites. A three-quarter turn hides the comparison, or you name it: both arms the same size. Motion clips make it worse, since the arms drift apart in size across the frames; a held pose with a starting frame is the stable route.
