Vaethat

Vaethat is a web-based AI enhancer trained on architectural visualization. It upscales renders 2x or 4x in batches, supports region and people refinement, and exports layered .psd files, with plans from €12 per month.

Vaethat is a web-based render enhancer aimed at architectural visualization. It takes finished 3D renders and raises their resolution to 2x or 4x while adding believable detail to materials, vegetation, people and fine surface textures. The underlying model is described as trained exclusively on archviz imagery, which is the main argument for choosing it over general-purpose AI upscalers that tend to drift away from the original design. The workflow is deliberately short. A user drops a whole folder of renders into a multi-image workspace, picks 2x or 4x, and presses Enhance. There are no prompts, sliders or presets to compare, so the same single mode is applied to exteriors, interiors and landscaping alike. Two optional controls cover the edge cases: Region lets the user draw a selection and refine only that area, such as a facade detail or a fixture, and People handles foreground and background figures separately. Results can be downloaded as a layered .psd with the original render as the base layer and the enhanced version above it, aligned to the pixel, so the output can be masked and blended in Photoshop or Affinity. Pricing is credit-based and tied to output size. Credits are calculated from the pixel area of the result, so a 2000 by 2000 output costs 4 credits and a 4000 by 4000 output costs 8. Plans start at €12 per month with 200 credits (up to 4K), with higher Professional, Business and Enterprise tiers, rollover caps on unused credits and priority queueing for subscribers. The site states that uploaded images are not used to train models, and that PNG, JPG and WEBP files are supported. The renderer is irrelevant, since the tool works on exported images from engines such as V-Ray, Lumion, Corona or Twinmotion. Vaethat suits visualization studios, architects and freelance 3D artists who want faster post-production without prompt engineering. Compared with broad image generators and general upscalers, it trades flexibility for consistency and speed. Anyone who needs creative re-imagining of a scene, or work outside architecture, will find it narrower than those alternatives.
