Realistic ArchViz from Cycles to Eevee (with tips)

architecture
(Eric Klein) #1

In this series will be doing different types of high quality architectural scenes in Eevee with tips and comments about the problems and solutions in creating realistic ArchViz in Eevee. The series includes a collection examples from ArchViz scenes in Cycles from Evermotion, Chocofur and others as basis to convert to Eevee.

My workflow and tips for realistic rendering are available in a number posts:

  1. Classroom benchmark classroom cycles to eevee.
  2. Realistic glass in Eevee realistic glass.
  3. For proper setting for shadows see link on Light Leaks.
  4. Lighting workflow see HDR lighting.
  5. Multiple or nested IRVs see link on Nested IRVs.
  6. Do a Cycles render pay close attention to the lighting specially the shadows. Shadows can be sometimes difficult to create accurately in Eevee but are critical for realistic rendering. Lastly material differences like glass. This will be good a reference starting point for your Eevee scene.

I will start the series with three scenes from Evermotion Volume 43 and continue with a couple of scenes from Chocofur.

Eevee completely dark room is still dimly lit

The Evermotion volume 43 scene 1.

Workflow:

  1. Adjusted power for area lights.
  2. World background node for ambient light.
  3. IRV for the main room of 4x3x3.
  4. IRV for kitchen counter of 1x1x1.
  5. IRV under stove.
  6. Rectangular reflection cube map.
  7. Use my realistic shader for glass items.
  8. New kitchen chair material the Cycles version did not work in Eevee.
  9. Tweak a few other materials.
  10. Increase sampling to 256 to smooth the shadows.

This is the Cycles Render:

The Evermotion volume 43 scene 2.

Workflow:

  1. Adjusted power for area lights.
  2. Use an HDR world background node.
  3. IRV for the main room of 4x4x4.
  4. Due to main room not being rectangular added IRV by the window of 2x1x4.
  5. IRV under stove.
  6. Rectangular reflection cube map.
  7. Use my realistic shader for glass items.
  8. Enable Subsurface Translucency for all the SSR food items see the grapes SSR as one example that come looking better than the Cycles version.
  9. Tweak a few other materials.
  10. Sampling rate of sampling of 128.

The Chocofur interior scene 1.

This is a heavy scene with grass and trees total vertices use is about 75 million.

Workflow:

  1. Adjusted power for area lights.
  2. Use an HDR world background node.
  3. IRV for the main room of 4x4x3.
  4. Rectangular reflection cube map.
  5. Most of the materials were update to use the principal shader replacing all Chocofur custom glossy and metal shaders. This shaders cause Eevee artifacts.
  6. Use my realistic shader for glass items.
  7. Sampling rate of sampling at 64.

This is the Cycles raw render:

The Eevee scene was adjusted to match closer to the composite version of Chocofur.

The Eevee raw render took 26 seconds:

The Chocofur interior scene 2.

This is medium complexity scene with plants, fabrics and cloth furniture. total vertices use about 4.5 million.

Workflow:

  1. Adjusted power for area lights.
  2. Use an HDR world background node.
  3. IRV for the main room of 4x4x3.
  4. IRV of 2x1x1 behind the sofa for better shadow definition.
  5. Rectangular reflection cube map.
  6. Most of the materials were update to use the principal shader replacing Chocofur custom glossy and metal shaders. This shaders cause Eevee artifacts.
  7. Use my realistic shader for glass items.
  8. Sampling rate of sampling at 256 to smooth the shadows on the floor.

This is the Cycles raw render:

The Eevee scene was adjusted to match closer to the composite version of Chocofur. Reducing the overblown window brightness and flooring from Cycles.

The Eevee raw render took 26 seconds:
