Every Project starts with research. To find inspiration for an architecture visualisation project I use

the Houzz Homepage https://www.houzz.de/

It starts with modeling the base room and the first lighting. Here I used the Corona Render sky and sunlight.

The next step is what I call “blocking” I add more and more assets into the scene and find the position of the furniture and decoration and also set up the composition of the scene.

Here you can see the white base preview render. It helps to see how the light and shadows react with all the assets in the scene. The wireframe mode shows how the meshes and the mesh flow look like. Also, it gives me an overview of how many polygons the scene has.

Materials:

I never use the inbuild materials from downloaded Assets. I always improve the materials. A lot of prebuild assets have wrong material settings or low-quality textures. I recreate the materials by using Quixel or GSG materials and textures. To have more control of the texture look I use the Corona color correction node, especially for the reflection channel to drive how the reflection looks. You don’t have to set up a high complex Nodetree every time to get good-looking materials. Good quality maps in Defuse, Reflection, Bump, Normal, and Displacement and a proper node connection and settings are the right way. You also can mix some imperfection maps and/or AO to add more life to the material.

Here is the example for the red berries.

Rendering:

After everthing is set up the rendering starts.

This are the masks I use: Sometime I need more and others

Here you can see the high-quality viewport in 3dsmax and the final render after some work in Photoshop.
