# Your design, brought to life with Agent Bob.

Bring Bob a sketch, photo, or model screenshot and explore lighting, materials, and atmosphere while preserving your design. This guide shows how to refine the presentation through conversation and request intentional changes when you want them.

The roofline is right. The windows are where they belong. The proportions took weeks to resolve.

Now you want to show someone what the finished building could feel like: sunlight across the facade, texture in the materials, a room that feels ready to inhabit.

You have already made the design decisions. Your visualisation tool should respect them.

That is the starting point for **Agent Bob**, your AI visualisation agent in Rendervis. Bob automatically respects the design you bring him. You can get straight to what you want to see.

## Your design is the starting point

Bring Bob a sketch, a screenshot from your 3D model, or an existing render. The architecture in that reference gives him the starting point for the visualisation: its form, proportions, openings, and composition.

Design preservation is built into how Bob works. You do not need to list every window or remind him to keep the roofline in every message.

Instead, tell him what you want to achieve:

> Bob, make this feel like a finished architectural photograph in soft morning light.

A short request is enough to start the conversation. Bob handles the image instructions behind it, so you can focus on the result.

## Explore how your project feels

A building can feel very different in crisp daylight and in the warmth of an evening scene. Material texture, reflections, and shadows help people understand a space before it is built.

Ask Bob for the atmosphere you have in mind:

> Show me this space on a quiet autumn afternoon.

Or:

> Make the lighting warmer and the timber texture more realistic.

Bob carries the design forward while working on the presentation. You can discuss the mood in ordinary language, without turning each message into a technical rendering brief.

## Ask for a design change when you want one

Sometimes you do want to explore a different material or test an alternative. Tell Bob directly:

> Try pale timber cladding on the facade.

That is an intentional change you have asked to see. Respecting your design means following your direction, including when you decide to take it somewhere new.

You can explore an option, discuss the result, and ask for another version in the same conversation. Your reference and feedback keep the work connected to your project.

## A conversation with Agent Bob

You do not need a perfect prompt to begin. Bring your project, ask for the image you are imagining, and refine it with Bob as you go.

The idea is yours. The design is yours. Bob helps you show it.
