Hi all.
I was going to post this in the this post ([https://forum.corona-renderer.com/ Flickering Shadow Issues #msg193691](https://forum.corona-renderer.com/ Flickering Shadow Issues #msg193691)) but not sure if it’s a separate issue.
I’ve need to do a rebrand on a job… changing colours, textures etc.
Other than that nothing has changed in the scene. It’s been recached and rerendered.
But as you can see it had an issue with lighting.
I had no issues with this the last time I rendered the animation.
I’m doing tests now.
Adaptive ON - has the issue
Adaptive OFF - the issue is reduced but still there
Lights > Occlude other lights has been turned off - no difference from the adaptive OFF test
The last animation was rendered with Corona 6. We’re now using Corona 7.
I’m not sure if installing C6 will fix it… but it’s a faff to have to do that.
Any help would be great.
Thanks
I’ve turned off all visibility settings on the lights (visible in reflections, refractions etc) - hasn’t made a difference
Here are the test renders:
4K or UHD Cache? What happens if you try the other one?

Hi.
I’m using UHD.
I’ve just installed C6 and am loading the scene now
I know…presume I have to redo the cache but I’m going to test it calculating every frame at first.. .will then test a cached version.
If none of those work I’ll test 4K. Unless you think that 4K isn’t worth testing.
If I get a working version with C6 then I may just stick with that for this. I was hoping to send it this week but doesn’t look like I can.

So, after a number of tests.
Using Corona 6 seems to have fixed it.
Which is both great but also frustrating as I need to recache it but it also wiped all of my render settings etc.
I’m going to keep testing to be sure.
One question… ummm, why?
Why would a scene that was originally rendered in C6 not work properly in C7?
I’m happy to send a scene over to you when I’m able.
I can send the C6 scene/cache & C7 scene/cache
I’ve even tried replacing ALL lights in the C7 scene. Replacer scripts are a godsend sometime. Nope… didn’t work either.
