30 years UE and translucent materials are still broken

For decades countless users were complaining about issues with translucent materials in UE.

As soon as you move the camera or the object with a translucent material on (even in scenes without any light) the material starts to disappear/jitter/noise like the engine breaks appart.

Using every hack on this topic like:

  • deactivate motion blur
  • set “Output Depth and Velocity” to true
  • in translucency pass set “after motion blur”
  • set “Opacity Mask Clip Value” to 0

does not help in all cases.

Do you really have to write your own shader+render pass to get a simple transparent material?

Not sure specifically on ur concern, but Epic has many many issues that they just ignore for years, decades and if i had to guess centuries once the company is old enough… But hey at least we get all these new features on top of the bugs/unintuitiveness

They really ought to hire a guy to go through and find all the QoL fixes and see what kinda stuff is like 2day fixes from the fourm and just do it, or pass it upward if its huge

Idk man, it gets even weirder than that also, sometimes the bugs u see in the viewport dont exist in a packaged project

Dito. I’m having one big bug per day on average (this was the one before). In most cases it turns out that this bug is known for decades but no developer was able to solve it.

Sadly bugs, Quirks and Workarounds, especially the workarounds are Epics theme,

Advanced sessions has done what epic could do in a single afternoon, possibly a single hour for 15ish years

alls they gotta do is expose more of the underlying variables that are already there

I’d say see if u package it does it behave the same way, and if it does then writing ur own shader or finding a really advanced workaround from years ago is probably ur only hope
