How credits work
Free accounts receive 50 starting credits once at signup. These credits do not refill each month.
Rendering charges vary with the model, resolution and, for some engines, processing time. Upscaling uses additional credits. The app shows your remaining balance.
Allow for retries and edits when planning a project. A credit balance does not represent a fixed number of finished images.
Masking an area for an edit
mnml.ai's Studio Edit Mode guide describes Select, Mask and Edit, drawing, object removal and enhancement. Its Mask & Inpaint guide explains how to brush over an area and describe the change with a prompt.
Rendero starts with scene segments that you can select for refinement. Check the selected region against the intended material boundary before sending an edit. With either approach, inspect narrow window frames, corners and neighboring surfaces afterward. A defined editing region helps direct the operation; the result still needs review.
Sharing an image for feedback
mnml.ai documents Studio project access for viewing, viewing with downloads, or editing. Those permissions make different handoffs possible; check the relevant team and collaboration terms for the people involved.
For an image review, specify which version needs feedback and what changed. Keep the original export available so another designer can check the camera, openings and material junctions. In Rendero, available engines and resolutions depend on the account's plan; compare the current options with the edits you expect to repeat.
