Hi, Arcane!
1Q. Artefacts in DXR, raytracing.
At the moment raytracing is very demanding. I have RTX2080Ti and there is the same artifact due to lack of memory.
At the moment, the temporary solution is a new regime.
I am still thinking about developing a less demanding solution, but we need time.
Unreal Engine 4.22. When raytracing mode is activated Raytracing Global illumination the plugin works, but very very slowly. A request was made to answerhub in the bug report of the engine. https://answers.unrealengine.com/que…0113/view.html . In the future, a new mode for working with ray tracing may be added.
- Received a response from the developers:
This is something that is expected. Since the scene capture is running ray tracing on a resolution dictated by the render target, scaling it up and down will have an immediate impact on performance. it is directly proportional to the number of pixels, so a change in texture resolution from 1024x1024 -> 2048x2048 will cause the ray tracing passes to increase 4X. RTGI in its current implementation is slow and very expensive. Keep in mind Ray Tracing is under active development so things may change as improvements are implemented with each engine verison.
- But with the new update, I added the experimental 360 recording and raytracing capability.
Try https://www.youtube.com/watch?v=6OiK2n6ZcSI Tutorial for 360 new mode.
I’m sure You’ll be able to render 360 with raytracing, as this mode uses a standard camera to capture and takes 6 frames in different directions.
But the main thing is to set the delay correctly.
- If the scene is large and very heavy, or very high resolution, you need to set the delay of the next frame 5-10 and more value (sec), delay screenshot is the delay between screenshots, example value (0.2-1 sec and more ).
You will deal with this mode, just need to configure the settings correctly. - You need to set a suitable quality in pixels, even 2048px is very good.
Watch the tutorial, I can create a new one for You if something is unclear.
2Q. Camera360 realtime.
Try attaching the point 360 to the camera and turn on realtime?
Can you record video of your camera setting and scene?
In the scene, I find it hard to navigate without seeing the scene.
Important not to confuse camera_point_360 and camera_point_2D !
3Q. Preview camera in scene.
Strange, in the new update preview camera looks good.
Maybe it’s the editor settings changed?
Try Editor Preferences -> find camera -> and change preview Camera size
I can try to connect to You via teamviewer if possible.
