Detailed introduction of some functions

Features

1. Geo and Sky system

  • On the Sky sidebar, a new ‘Geo and Sky’ system is added next to HDRI. We can control the sunlight by modifying geographical parameters like time, date, longitude, and latitude. Unlike HDRI which contains parameters that directly control the orientation and color of the sun, the Geo and Sky system needs real geographical information to calculate the sun’s position and light changes, and outputs extremely realistic results.

  • If you want to accurately control the angles of sunlight, you need to use the HDRI system which provides customizable parameters of the sun.

  • The earth model shows the relative position between the sun and the location we set. When the sun is right on the left horizon, it symbolizes the time of sunrise, and a sunrise light effect will be displayed in the scene as well. When the sun is in its 12 o’clock direction (right above), the solar height of the place reaches its maximum value. If the sun is below the horizon, a night effect will be displayed.

  • The position, time of sunrise and sunset, and the lighting effect are accurately calculated according to the Month, Date, Longitude, and Latitude parameters.

  • The North offset parameter is designed to recalibrate the north direction of a scene. It is like a compass pointing to the north. Modifying the parameter changes the original direction of the pointer (also known as the azimuth of the sun), and the sun will move on a circle parallel to the horizontal plane.

2. ‘Focus On’ the model

  • After selecting the model in the list or scene, click ‘Focus on’ or use shortcut key Z to quickly move the camera to the front of the model, so that the model can be fully displayed in the view. This feature adds convenience to locating models in a scene.

3. Hide the inspector panel on the right side of the window

  • We can click Window → Hide Inspector to control whether or not to display the Inspector panel or use shortcut key F11 to do it quicker. It solves the problem of the Inspector blocking the scene when adjusting models and materials or setting the picture rendering parameters.

  • *We have also redesigned the layout, and will gradually optimize the window layout in the following versions.

4. Extended Model Replacement feature

  • Previously, we could only use local files to replace a model, be it imported or from D5 Assets Library. Now, we can also replace models with assets from Online/Local libraries.

  • Select a model in the scene, click Replace → Replace from assets, then choose a new model to replace the current one.

  • The models need to be downloaded from Assets Library first.

5. Foliage Material template(Double-Sided)

  • A new Foliage Material, also named double-sided material, is added to the Material Template list, which is often used to make plant leaves

  • We can upload maps in Subsurface Color. Opacity maps and Opacity intensity adjustment are supported.

6. Supported Color adjustment for plant assets

  • Use the material picker to select the material of plants, then adjust the map color in Inspector.

  • If we use the brush tool (or the scatter tool) to insert plants, the color of brushed plants (of the same kind) will change at the same time when adjusted; if we insert plants in a normal way (by placing them one at a time), the color adjustment only affects the individual plant we select.

7. Supported separate adjustment for Sky Light and Background Light Intensity

  • Click the control button next to Sky light intensity to show Background. The parameters will be adjusted at the same time when the Background option is collapsed.

  • The separation of the two parameters adds more flexibility in doing light control of the scene, making it possible to better integrate the subject of the scene and its background. It avoids the situation where an appropriate light sense appears in the same picture with an overexposed background, or the body of a scene looks dark while the sky background is bright.


8. A Light source Radius parameter is added for Point Light and Spotlight, which controls the realistic effect of light source shadows.

9. Added mapping for Emissive Light

  • A new intensity map is added for Emissive Light. We can now add a black-and-white map In the brightness parameter to control different luminous parts of the Emissive Light material .

  • At the same time, three parameters related to Emissive Light: Intensity, Color and Cast shadow are combined into a switch control. Turn on the switch to set the Emissive Light effect


10. Added Transparent Material Channel Map for rendering pictures

  • In previous versions, the exported material channel maps did not include channels for transparent materials. In 1.9.0, a separate transparent material channel map is added making it easier to carry out post-processing for transparent materials, such as glass

Rendering

11. Optimized the emissive effect

  • Based on an appropriate hierarchical space division of the luminous geometry, and the importance projection sampling points of Grid, D5 can carry out multiple importance sampling. With the help of world space noise reducers, we can generate emissive projection effect accurately and swiftly, making it suitable for all kinds of shapes and sizes of geometry.

12. Optimized Water Material effect

  • Thanks to the new physics-based simulation of light scattering and absorption, water material now has a better performance in textural depth and color transition.

13. Optimized the Fog reflection effect, added the Sunlight Tindal effect support for specular reflection

  • With raymarching in ray tracing reflection, D5 samples light grid and shadow map to simulate extremely realistic ‘God light effect’

14. Added glass reflection to specular reflection in rendering results

  • By adding transparent material support to multiple-reflection ray tracing, we can get a high-quality reflection effect of transparent materials through multiple bounces of reflected rays.

15. Another upgrade for the global illumination

  • The scene illumination information is cached based on the position of objects then sampled adaptively according to various conditions, in order to reduce the light leakage and enhance the accuracy, further approaching the offline rendering quality.

16. Improved Low-quality effects in editing mode

  • After switching to low-quality preview mode, light sources in the scene will no longer produce shadow effect on objects, which can improve the editing efficiency

17. Great improvement in rendering efficiency:

  • The system consumption of the multi-sample sampling process in the underlying engine is optimized, and the speed of taking pictures is increased by more than 20%

18. Optimize the calculation efficiency of plants in large scenes

  • Optimized the mapping and invocation of plant instances in the rendering process, and improved the load capability of complex large scenes by 50%

19. Expanded range of video roughness

  • The adaptive range of reflection roughness in video output is expanded, and when rendering videos, what we see in real-time preview mode is exactly what we will get.

20. Curtain material supports penetrance effect

  • Based on the new shading model, the curtain material supports fast subsurface scattering, which makes it easier to simulate the lampshade effect.

Productivity

21. Supported RGB, HSV, and HEX modes, as well as an on-screen Color Picker for color controls.

22. Optimized HDR, LUT, IES file selection controls, supported multi-selection and group setting of IES files for Spotlight.

Assets

23. Added 412 Asian Plants

yeah, we have been developing this.

Just updated, and when I opened my previous project all the lights seem to be extra bright and have messed up with the entire lighting scheme of my project. Anybody knows what could be a reason for this and can someone help me with a fix ??/

Hi, the light you mentioned is a normal point light or emissive materials? It would be good if you could share a screenshot with us, or post a new topic directly, I will follow it up for you.

I have used rectangular lights and spotlights. , I m attaching 2 images before and after the update.

  1. TDR detection is newly added. Please restart the computer after starting D5 with the administrator’s permission according to the prompt. This can improve the in-use stability of D5 Render.
  2. Assets in the Assets Library are upgraded in the new version. When opening a scene file saved from version 1.8.1 with version 1.9.0, it could take some time (based on your internet connection) to update all the assets if your scene has a lot of assets of different types from the Assets Library.





Known issue Description and workaround
[1.9.0]Some materials leak/glow light in the scene. Solution: First, ensure that it is a double-sided model without overlapping, then we can try to lower the Specular parameter of the material.
[1.9.0]Noise appears on some materials irradiated by emissive materials. Solution: Noise may occur on the material with too large parameters of Normal and Specular when emissive materials irradiate on it. This problem can be solved by lowering the Normal and Specular parameters of the material.
[1.9.0]The bloom effect acts differently according to resolutions. Solution: The current logic ensures that the bloom effect during preview is consistent with that of 4K render. The larger the size of the output picture, the more obvious the bloom effect is.
[1.9.0]Suggested adjustment of water materials. The water template has been optimized in 1.9.0. In order to fully display the effect of water, we need to pay attention to the following:
  1. When modeling, the water material itself is a single-sided model
  2. When modeling, a plane (i.e. water bottom) is required under the water material model
  3. If water fills the screen view, the water material at the edge of the view will flicker. Please try to avoid this kind of view when rendering videos.
  4. The color of water is accurately controlled by Color [Hue, Saturation, Value] of the material panel and the [Depth] parameter of the water material template.
[1.9.0]The depth of field appears differently in preview and render. Solution: When the depth of field effect is needed, it is recommended to turn off DLSS to avoid this kind of problem.
[1.9.0]Unable to add keyframes to camera clipping parameters. Cause: The camera clipping adjustment is not supported when taking photos in video editing mode.
[1.9.0]Blue pieces appear after rendering a picture. Solution: When some special LUTS are used, blue light pieces may appear in the image. It is recommended to replace the LUT files with those from other sources or use the default LUT of D5, to avoid this situation.
[1.9.0]When using Camera Clipping Plane with camera outdoors, the ambient light will penetrate the building and enter the interior. Solution: Move the camera indoor first, then use the Camera Clipping Plane feature.
[1.9.0]When the focus of depth of field is set on glass materials, objects far behind will be clearly displayed through the glass. Cause: If we set glass materials as the focus of depth of field, the object behind the glass will be recognized on the same plane as the glass is. Even if the object is far away, it will be clearly displayed in the picture.

Solution: In this scenario, try not to select glass as the focus. You can select objects near the glass as the focus, and the view will return to normal.

[1.9.0]The darker parts of the screen flicker when previewing. The dark areas in the scene flicker when the Realtime option is on. Even if the DLSS is turned off, it still flickers.

Solution: Turn off Realtime, the view will return to normal.

[1.9.0]If the Tyndall effect is turned on, the fog may be divided after rendering pictures. Solution: This problem can be avoided by turning off two-point perspective and rendering again.
[1.9.0]When there are multiple scenes in a single video clip, the camera movement is automatically smoothed. Solution: If the smoothing camera movement effect is not needed, we can split the keyframes of a clip and divide the movement of each shot into different segments.
