[BUG] Beta6 Black viewport with super bright spotlights

Development Asset Creation

So i have 30 Movable Spotlights with brightness set to 30000000. But when i enable realtime the viewport keeps on rendering black as we move the camera and eventually it covers the whole viewport. Here are some screenshots:

You can see my spotlight settings (30 lights) on the details tab:

As we move the camera the blackness keeps on growing and eventually covers the whole viewport:

But if i turn off realtime the whole blackness is gone:

Again if i turn on realtime it comes back.

Hi Satheesh,

I have tried testing this and I have not yet experienced any issue.

Are you able to reproduce this issue with Spotlights on the Default map, or on a blank map that uses only BSPs? If so, I would appreciate if you could send us the .umap asset as a simple test case.

Also, what are your system specs with regard to your graphics card?

Thanks

#Turn off Light Shafts / Bloom on All Light Sources

You know that new feature they enabled in Beta6? The Sun Shafts Bloom?

Turn that off

:slight_smile:

I encountered the same problem, and the above fixed it for me.

I dont think the Light Shafts are fully done yet.

I have had to disable that new feature in my game because of this issue.

I did not have time to take good pics of the issue graphically, so I am glad you did!

Let me know if this fixes it for you!

#For Epic Debugging

I encountered the problem not when many many lights like Satteesh, but when I had a single particle system with many many self-lighting sprites. (no particles, just regular textures)

#My Analysis

I think that when the bloom / light shafts intersect with too many other light sources between the Light Source of the Shafts and you/the player camera,

some sort of buffer gets over loaded.

In my log I believe it said something about the GBuffer

Hi Rama,

Restarting the editor seems to fix this issue. This issue happened to me yesterday and today when i opened this project there is no such issue (so far).

yea it doesnt happen immediately, I sometimes had to be ingame for awhile before it would show up

if it does show up try my solution and let us know!
