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.
Selecting a material to change
Gendo documents region selection for material changes, alongside chat-based editing, parallel rendering and upscaling. These tools sit on the same canvas as sketches, model exports and reference images. Gendo's product page includes examples organized by editing task.
Rendero uses scene segments to define areas for refinement and accepts reference guidance. For a cladding change, inspect the selected area around glazing and adjoining surfaces before rendering. Afterward, compare those edges with the source. The presence of a selection tool in either product does not establish which output will need less correction.
Keeping versions ready for review
Gendo's current Studio plan lists up to five team members, unlimited viewer seats, and private or public sharing links. Its Free plan lists up to two team members and public-only links. Compare those roles with the people who need to edit or review images under Rendero's per-person plans.
Keep the source, the requested material and the accepted version together when handing an image to a colleague. Record any corrections still needed around openings or material boundaries.
Rendero's available engines and resolutions depend on your plan. The segment review guide covers selection checks, and product facts describe the image workflow.
