This is my interpretation of a Tezuka House by the forest, played with different foliage types as opposed to the original site itself. My intention was to achieve that “forest” look with lush vegetation while preserving the focal point which is the design of the house itself. It was a simple 3D exercise which I did to pass the time.

First let see how we end up…

The final render

Preparing the Scene, Setting the Ground Work.

I prepared the site with a plane as the base, pulled some vertices on the z axis to achieve an uneven terrain. This will create the rolling effect especially in the background areas of the scene. The ground is applied the grass material, then proceeded with the house structure itself.

STEP 01 SITE 528x264 Making of House to Catch a Forest

The site

The house structure itself was not that difficult to create, it is mostly comprised of extruded splines (the walls and floors) or editable splines (such as the rails). As a rule I try to use the simplest mesh as possible so as to allow me more flexibility in editing in later stages. I only resort to polys on a case-to-case basis. Furniture for the interiors is a separate issue.

STEP 01 HOUSE 528x264 Making of House to Catch a Forest

The house

I always choose a texture which has a good tiling quality and not obviously repetitive when rendered. Also as a rule I try to avoid using high resolution textures if the scene does not showcase them close enough. For example, the concrete material I used was some random mid-res set of concrete textures which I cropped in the material editor and it is more than enough to suit my purpose in this exercise.

STEP 01 HOUSE MATS CONCRETE 528x445 Making of House to Catch a Forest

Concrete material

Assigning the Grass Material

I then applied the grass material as shown, I intentionally modified some patches to show some ground textures rather than full grass alone, to achieve a more natural effect.

STEP 02 GRASS MATERIAL 528x264 Making of House to Catch a Forest

Grass material

Adding a Grass Displacement

Using the same bitmap, I added a VRay displacement modifier to the ground mesh.

STEP 03 GRASS DISPLACEMENT 528x264 Making of House to Catch a Forest

Grass displacement

From this point onwards, all plants and trees come from pre-existing tree libraries such as evermotion which were generously shared by some friends.

Adding 3D Grass Elements

To enhance the scene further I opted to use 3d grass meshes with the material applied as shown in the image. The grass was applied with a gradient material, with a texture map applied in the middle tab, as shown. These were the default settings of the grass mesh. No UV Map was applied.

STEP 04 GRASS PORTIONS 528x264 Making of House to Catch a Forest

Grass strands

Rocks

The rocks were placed and assigned the material as shown in the image, with a bump value (100). Some of these rocks are available in preset libraries, but these were modeled using poly’s. The texture is also as shown in the image.

STEP 05 ROCK 528x264 Making of House to Catch a Forest

3D Rock

Supplementary 3d Plants

The scene was then peppered with various species of plants. These models are all preset including their materials, however to add more realism to the final output, I opted to follow the next step…

STEP 06 SAMPLE PLANT 528x264 Making of House to Catch a Forest

Sample 3d plant

Plant Glossies

For most of the plants that I used in the scene, I have applied a glossy reflection to the leaf materials. A value of 20,20,20 in RGB is what I used in this instance.

STEP 07 SAMPLE PLANT GLOSSIES 528x264 Making of House to Catch a Forest

Plant glossy reflections

3d Trees

The forest trees were then inserted into the scene, with the default material applied. However, similar to the plants, some parameters were added.

STEP 08 TREES 528x264 Making of House to Catch a Forest

3D Trees

Tree Glossies

Similar with the low plant leaves, glossiness was also added to the leaf material as shown. Also in 20,20,20 in RGB.

STEP 09 TREES GLOSSY REFLECTIONS 528x264 Making of House to Catch a Forest

Tree glossy reflections

Other Tree Settings

Also incorporated a refract value to the leaf. RGB 30,30,30 in this example. These settings were all default to the tree mesh when it was obtained from the 3D library. Translucency and bump are as illustrated below.

STEP 10 TREES GLOSSY REFRACTIONS 528x264 Making of House to Catch a Forest

Tree glossy refractions

STEP 10 TREES TRANSLUCENCY 528x264 Making of House to Catch a Forest

Tree translucency

STEP 10 TREES BUMP 528x264 Making of House to Catch a Forest

Scattering the Trees and Foliage

I have not been able to use VRay Scatter for this exercise, just manually populated the scene with the plants and trees where I see fit. It is important to make sure that the proxies and/or 3d plant meshes had their anchor points slightly above the ground level to allow for some “submerging” of the meshes below the uneven terrain.

STEP 11 SCATTERING01 528x264 Making of House to Catch a Forest

Scattering pivot point

After making sure all the plants are in their proper pivot points, I proceed to scattering the plants. The obvious method is of course to create one instance, select both, then instance (hence 4), etc. which is simple multiplication of the objects.

STEP 11 SCATTERING02 528x264 Making of House to Catch a Forest

Scattering the plants

After populating you can see that they are all in the same z axis. In order for these objects to align with the ground plane, I used a tool called scripted glue. It’s quite easy to use. This applies to all of the plants and trees in the scene.

STEP 11 SCATTERING03 528x264 Making of House to Catch a Forest

Positioning plants above plane

STEP 11 SCATTERING04 528x264 Making of House to Catch a Forest

Plants after glue script

There is also this neat tool from called randomizer-0 which randomizes the size and rotation and even the scale of selected objects. A helpful script to randomize the foliage.

STEP 11 SCATTERING05 528x264 Making of House to Catch a Forest

Trees & plants after scattering & randomizing

Lights

Lighting for the scene is pretty straightforward. Using VRay Sun (with the default VRay Sky environment), a general VRay light for the ambiance, and an interior yellow light was all that was incorporated into the scene.

Light Settings (all using 8 subdivisions only)

Camera Setup

Nothing fancy here. Just used a standard camera with the following settings. In Rendering however, I used the blowup option to render only the area of concern in the scene.

CAMERA RENDER BLOWUP 528x264 Making of House to Catch a Forest

Render Settings

Mostly default. I experimented with Reinhard for the color mapping, quadratic as AA and 1,6 for the DMC settings. The rest are as illustrated below.

Render settings 1/4

Also applied an HDRI map to the reflection slot. The map was obtained from a good source of free HDRI maps: http://www.hdrlabs.com/sibl/archive.html

Rendered Output and Post processing

Finally! Got the raw render after a few hours of waiting. The resolution was 2500 pixels and took almost more than 8-10 hours to render (the price I had to pay for extreme glossy materials). Here’s the initial output below.

RENDER PP 01 RAW 528x396 Making of House to Catch a Forest

Raw render

Decided to add a sky bitmap background to enhance the scene. The result below.

RENDER PP 01 SKY 528x396 Making of House to Catch a Forest

Sky background

Still not entirely a good sight because the sky needs more tweaking, and the overall effect is a bit dark in the shaded areas. For this, I applied some postwork, using mostly curve adjustments.

Finally, played with a few shots and cameras…

Hi,

Awesome pic congrats !

Just noticed you left the default memory setting in the "Settings" tab under "Vray:: System". If you have 8 Gb, you should put 8000 in the "Dynamic Memory Limit" and choose "Static" from the "Default geometry" drop-down menu. Your light cache pass should be faster this way.

Rémi

Nice tutorial, I have a question... why didn't you use the LWF settings on this scene, VRay frame buffer and VRay camera?

Celes
Celes

I was kind of new to LWF when I did this, so I chose to use the old gamma settings. I also did experiment with Vray physical camera in the night scene. I think it's a matter of whatever way / tools that would give you the results you want. :) I guess I just chose to use the old tools that's all.
