Creating Evening Cabin Scene - Tip of the Week

Making exterior visualization in Blender with Archmodels.

 

I made this scene to test the latest models from Evermotion in different environments. I downloaded the cabin from Evermotion Shop. It comes from Archmodels vol. 254 collection and it is available in 3ds Max, C4D, FBX and OBJ versions. I decided to work with FBX format so I imported it to Blender.

To speed things up I use Machin3Tools free add-on for Blender which gives me this fancy pie menu with various options.

Among other options it allows me to import and export FBX and OBJ files by pressing “CTRL-S” and choosing desired option, which is fast and convenient way to work with external files. I higly recommend this plugin.

My FBX building imported without problems.

I only need to take care of glass material, because it was not assigned as transparent in Blender. So I selected window mesh, deleted the original material and created a node tree for glass in Blender that looks good, but it is also fast to render:

This node setup mixes Glass and Transparent shaders and uses Light Path information to determine which will be visible to camera. If Shadow Ray reaches camera, mesh is transparent, if the mesh is not in a shadow it will be rendered as glass. It is the simple mnethod that is commonly used by Blender users for windows, flat glass surfaces, etc.

I needed some base for my building, a ground plane. I created a simple 2d plane and subdivided it a couple of times. Then I switched to Sculpt Mode (Blender has a really decent set of tools for sculpting) and pushed and pull some vertices to make it look like a natural, curvy terrain. Nothing very detailed, just some simple stuff to create a height variety.

Then I returned to Object Mode and subdivided a plane once more. I wanted it to be quite high poly, because it was meant to be the base for scatetring vegetation. I also wnated to get some smooth curves.

I turned “smooth shading” to ensure that my ground will look smooth and curvy in render. I used a wide angle 26 mm camera close to the ground to show the silhouette as more majestic and pronounced.

Now I needed the texture for ground. I used rocky ground texture from Quixel Bridge. The latest Blender 2.94 works very well in cojunction with Bridge, you can easily export all assets from Bridge in one click which speeds up the process of creating materials and scenes.

The textured is tiled, as you can see, but it will not be a big problem, because the most of it will be covered with vegetation.

The only change that I made was increase the tiling from 1 to 3 in Mapping node.

I wanted nice vegetation to be scatteres on my plane, so I tried the great Blender plugin - botaniq. It allows you to scatter different biomes and many trees with variations and they all look fabolous! It is also very simple to use, it was my first attempt with this plugin and I really like the results.

AND HERE COMES THE GREAT STUFF: now you can download Botaniq 25% off with a code: evermotion25. You can use it on BlenderMarket, just add Botaniq to cart and use the code during checkout.

 

First, I scattered some grass from European meadow biome around the house. If you add biome, it scatters it evenly on the whole selected mesh, but then the fun begins - just select a brush button and start painting your greenery on a plane using weight paint. It works like a charm and is very simple and artistic-friendly solution for creating complex greenery.

Voila! Like a Van Gogh, but without sunflowers!

I added a bit of alpine grass for some variation. Well, a little more than a bit - 100 thousands to be exact. total number of scattered assets was 159 thousands at this point and my viewport started lagging, luckily botaniq has a solution for that - I could reduce the number of particles visible in viewport as much as I wanted.

 

image23_0627_noresize

 


 I reduced the number of visible particles to 15%. 

 

image5_0609_noresize

 


Now everything works smoothly and almost all assets are here. Let’s check it out!

Looks better already, but I need some trees to hide the empty space behind the building. Botaniq can help me with that too. I added a third layer of foliage - "tall grass", but reduced a scale a bit.

The plugin comes with a wide library of trees, flowers, shrubs and many other assets suited for every season. Here you can see corniferous trees selection.

 

image14_0618_noresize


I addes some trees, one by one, placed them around the house, I could use some variations, but in this case the only thing I needed to avoid repetition was rotating some models on Z axis.

 

image7_0611_noresize

 

image10_0614_noresize


I wanted to introduce some atmosphere to the scene and I think that one of the best solutions for that is using volumetric materials in Blender. I created a Cube and changed it visibility to “only wireframe” in Blender, so it will not obstacle my view during work.

 

image18_0622_noresize


I assigned Volume Scatter material to it. I also played with rotation, to change the positioning of the fog.

 

image17_0621_noresize


This way, as you can see, the fog is more dense further from a camera and it almost is non-present around the house model, which is perfect for - me - I didn’t want it to hide any details of the house I was going to render, I only needed it as a moody background.

 

image20_0624_noresize


I decided that I will use HDRI map to lit my scene. I used Lillenstein map from HDRI Haven.

 

image19_0623_noresize

 

...and tweaked it a bit with nodes (brightnes, contrast, etc.).

 

image22_0626_noresize

 

Nice! it is starting to look like a gloomy, mountain night scene with a cosy cabin. The problem is that cabin does not look cosy at all, it is dark and abandoned. Let’s change that.

 

image8_0612_noresize

 

I needed some interior lighting to brighten my hero building. So I I used six point lights in Blender.

 

image12_0616_noresize

 

image9_0613_noresize


Much better now! The last thing is to use Depth of field of the camera to blur foreground greenery.

Ok. I think that this image is ready for post-production. I use Davinci Resolve in my daily video work, it is one of the most sophisticated apps for working with color, so I figured that it will be a perfect soft for color grading. Luckily, Blender can export OpenEXR files, that are perfect for grading.

 

This is like my Node Tree looks like in Davinci Resolve. It's not really that complicated - grading still images is fun and simple!

 

Untitled_0631_noresize

 

My first node is "primriy controls node" - I tweaked shadows and light tones a bit with the wheels and added a bit of saturation to the image.

Untitled_0632_noresize

 

The next node was made for tweaking sky tone. I selected sky color with eye-dropping tool and tweaked this mask a bit with the sliders, then I added a bit og blue tone to the sky.

Untitled_0633_noresize

 

I wanted the wood to be a bit lighter so I selected only wood color and tweaked it in another node.

Untitled_0634_noresize

 

The next step is a little cheat - I used LUT from Roman Hense to adjust overall look of the image. I dropped the amount of influence of this node to 0.798 as you can see.

Untitled_0635_noresize

 

Another "magic" node is FilmConvert tool that lets you to simulate different analog film looks. I used Kodak KD 5207 to bring some vintage feeling to the image. This node also adds a little grain to the final image.

Untitled_0636_noresize

 

I added a glow to the light sources with Sapphire Glow node. But you can use also stock Davinci glow effect - it works really well.

Untitled_0638_noresize

 

At the end I sharpened the image - in DaVinci you can do it by pulling radius to 0.47 and it is enough in the most of the situations.

Untitled_0639_noresize

 

And here we have it - the final image after post-production :)
