Blurry Renders in Unreal Engine 4.25.3 - How to fix
After using Unreal Engine for rendering on a number of product animation projects, we encountered the issue of: Blurry Renders in Unreal engine 4.25.3. Previously all a user needed to do, was to create a cinema camera actor, and a level sequencer, and then, populate the camera field in the level sequencer with the cinema camera actor. From there one could pan and position the camera, create an animation, determine a strat and end frame. And finally one would simply hit the clapper icon, to render out a cimenatic quality sequence. Saving on the long render times one experiences when using packages like VRay. This produced fast crisp renders. But with Unreal Engine 4.25.3, running a ATi 730, this was no longer the case. Renders came out with alot of blur, and textures looked soft. This was no longer something we could use in production. After much searching we found, that unreal had updated the process. Enter, the "Movie Render Queue. This brings the traditional offline rendering workflow on UE4. No longer does one render such sequences in real time, but now we have a workflow similar to other offline renders. Its still fast. But now offline.
Offline RTendering with Unreal Engine 4.25.3 - The Movie Render Queue
So the workflow here, is to create your level sequencers, with your camear shots/cuts, as previously. But now what you do, is go to the Movie render queue interface and load up those level sequences there and then render. The user has the option to customise the qulaity a great deal using "console variables". This provides control over the number of GI bounces, bloom quality, anti aliasing etc. The full doucumentation for this process can be found here:
The assumption made is that the user is rendering with an NVIDIA card, with raytracing enabled. Here's a link to information pertaining to this:
With the default settings provided in the Movie Render queue doucumenation, we ran into issues with banding in the renders. This was resolved using our own anti aliasing settings. You can check them out in the video below.
