Why is the effect of the glass material not obvious/anomalous?

There may be the following reasons:
Previewing in Smooth mode, the glass is displayed incorrectly;
You can try to increase the specular value to improve the reflection of the glass, the glass effect will be more obvious;
If the glass is currently multi-layered, remove the multi-layer structure and leave only one layer (currently D5 does not support rendering reflections on the glass surface behind the glass);
You can reduce the transparency of the glass a bit and make the glass create a shadow;
Glass-to-glass reflections are not shown in the preview and are only calculated when out of the picture/video;
If the current glass has no thickness, you need to give the glass model a certain thickness in the modelling software or turn on the thickness switch in the transparent material template of D5.
Streaks of flickering
The coordinates of the glass model are too far away from the world coordinate origin (0,0,0) to cause this anomaly.
Solution: Select the model in the scene resource list and zero the model coordinates in the right sidebar.
There is a difference in the effect of the glass when it is moving and when it is stationary
The effect of multiple reflections between glass is not displayed when the camera is moving.
Multiple reflections between transparent objects are automatically calculated when the screen is stationary, as well as the colour and transparency of the glass material will be involved in the calculation of the reflection effect.
Therefore, the preview is closer to the actual image when the FPS is stable.
Refraction/ Reflection effect is not correct
Single sided models imported into D5 and given a transparent material will have incorrect refraction and reflection effects.
Solution:
It is recommended to regulate double-sided modelling to avoid such problems.
Or turn on the "Thickness" parameter in the glass material template parameter, which can simulate the plate glass with thickness, and the single-sided glass can get the correct refraction effect.
Considering the performance in preview/output, there is a limitation in D5 on the range of plants displayed in the glass reflection:
Models in front of the camera and not in the camera's viewport are 150m in real time and 900m in output.
Preview/output behind the camera is both at 150m.
Starting with 2.8 version, users can adjust the Engine.ini file to get complete preview/output effects.
Note:
If modify ↓ configuration item, the corresponding preview/output performance will also be degraded. (If you are not sure whether to use this option, please contact the official for detailed confirmation or operation.)
( No need to open D5 ) Find the file C:\Users\XXXX\AppData\Local\d5_immerse\Saved\Config\Windows\Engine.ini
Add the appropriate fields in the Engine.ini file, modify the parameters and save.
Restart D5, the relevant configuration changes will take effect.
