Render your Blender viewport with AI — images and video from a blockout

Blender is the fastest way to decide where things go: a camera, three grey boxes, a light, done in five minutes. What it is slow at is making that blockout look finished. The eroq add-on closes the gap from inside Blender — snapshot the viewport, describe the look, and get back a rendered picture or a video clip that keeps your composition. This guide covers the install, the one switch that matters (Keep composition), and where results land.

Install and connect

The add-on works in Blender 4.2 and later, 5.x included.

1. Download the zip from eroq for Blender.
2. Edit → Preferences → Get Extensions → Install from Disk… and pick the zip — or drag the zip onto the Blender window. If Blender asks, allow online access (Preferences → System → Network); the add-on only talks to eroq while it is on.
3. Open the sidebar with N in the 3D Viewport, go to the eroq tab and click Connect eroq. Your browser opens eroq.ai; sign in and click Allow. The panel header now shows your credits.

Blender gets its own key, listed as « Blender on your computer (connected) » under Developers → API keys. It lives in Blender's preferences, never in your .blend files.

From blockout to picture

Set up the shot the way you would for a render: camera, rough shapes, maybe a light to say where the sun is. Then, in the eroq panel's Image section:

1. Write the prompt as a description of the finished frame: « rooftop bar at dusk, wet asphalt reflecting neon signs, string lights, two figures at the railing, 35mm ». Long prompts can live in a Text datablock (the T toggle).
2. Pick the model and the aspect — 16:9 for a shot, 3:4 for a poster.
3. Set Reference to Camera snapshot (the scene camera, at the render aspect) or Viewport snapshot (the 3D view as you see it).
4. Leave Keep composition on and press Generate image.

With Keep composition on, the snapshot is edited: your prompt becomes an instruction and the layout, the horizon and the framing of the blockout stay where you put them. Turn it off and the snapshot becomes a looser reference — its colors and subject inform the render, but the engine recomposes. Engines without an editor say so and charge nothing.

The render loads into the file and opens in any Image Editor you have. From there:

• Add as plane — a mesh plane at the picture's exact aspect, textured with it. Useful for a background card behind your 3D foreground.
• Add as reference image — an image empty at the 3D cursor, facing the view, for modelling against.

A picture costs 10 credits on Krea 2 (20 on Eroq One).

From blockout to clip

The Video section takes the same inputs plus a duration (3, 5, 8 or 10 seconds), an aspect and, on engines that render sound, a Sound switch. Set Start frame to a snapshot and the engine animates your composition: on engines with image-to-video, the snapshot is literally the first frame.

The estimate under the pickers follows each engine's billing — it snaps the duration to what the engine renders and prices resolution and sound. For scale: a five-second clip on Seedance 2.0 Mini is 45 credits, and Motion One, eroq's own engine, is 60 a clip.

Renders take one to several minutes, and Blender does not freeze while you wait — keep modelling. The clip lands on the Video Sequencer at the frame where you pressed Generate, on the first free channel, with its sound on the channel below. Two practical notes:

• Frame rate. Most engines render at 24 fps. If your scene runs at another rate, the add-on retimes the strip so it plays in real time; if Blender cannot (Blender 5.2 refuses when image or effect strips sit earlier in the timeline), the status line tells you to set the scene to 24 fps.
• Start frames go through Storage. The video API takes picture links, so the snapshot is uploaded to your eroq Storage (folder « Blender ») first. No credits, it counts toward your storage quota, and you can delete it in Studio → Storage.

Voice lines on the timeline

The Speech section reads a line with a roster voice or one of your cloned voices and drops the MP3 on the sequencer at the playhead — a quick way to put temp dialogue under an animatic. Voice One costs 3 credits per 100 characters.

Where the files go

With a saved .blend, renders go to an eroq folder next to it and are linked with relative paths, so the project stays self-contained. An unsaved file writes to ~/Documents/eroq/. Files stay external rather than packed, and every render is also kept in your eroq library.

A workflow that works

1. Block the shot with primitives and a camera. Do not texture anything.
2. Camera snapshot + Keep composition + a prompt about light and material: iterate on the look for a few pictures.
3. When one lands, add it as a plane behind your hero asset for a quick composite — or use the same snapshot as the start frame for a clip.
4. Put a temp voice line under it and you have an animatic in an afternoon.

FAQ

Do I need to know how to write prompts for this?

Less than usual. The snapshot carries the composition, so the prompt only has to describe what things are made of and how they are lit.

Is the add-on free?

Yes. Renders cost the usual credits; new eroq accounts start with 50 free ones.

Does it work on Windows and Linux?

It is pure Python with no dependencies and runs wherever Blender 4.2+ runs. The beta has been tested most on macOS.

What happens if I close Blender during a render?

The render continues on eroq and lands in your library; it just will not be placed in the file. The ✕ next to a running job does the same on purpose.
