Loads of speckles when object reflects itself

[tricky]

Any news on a solution to this? We are having the same issue with a HDR (with a sun in it) on a vraydomelight.

Another way to avoid the problem is to use the VRayOverrideMtl material and use a different and simpler material for the reflections.

If we were to do this, it would take away a big part of the subtlety achieved when using a HDR.

Hi Tricky,

Can we see your scene, if you have time please send us an email to : support@chaosgroup.com
Thank you.

Svetlozar, I sent a scene file to support@chaosgroup.com

Still having that issue, take a look at the screenshot.

Ive had this issue recently too. Ended up just Pshopping it due to time. Seemed intermittent.....

[Morbid Angel]

can you post a part of your scene here...

We just had the same problem here

We ender up having to use the sub pixel mapping, and clamping at 3-4, and dupe the HDR vraydomelight. uncheck the reflection in the original domelight and only affect the reflection in the second dome. edit the hdr and clamp manualy the sun in the HDR at something like 1-2 by painting on top of the overbright sun.
my boss came with all those tweaks after looking at my render because he was used to that bug, so I guess it's not something new...

Just wanted to know if anything came out of the scene I sent. I am having this over and over again, in nearly every render I do...

I had this problem a lot of times... the way I got it sort of fixed was to use Clamp at 1-4 value... Other than that its noisy whh.

Hope there will be fix for fireflies.

Thanks, bye.

For the 3.x builds, we added an option to clamp reflection rays; it's lame but I can't think of anything else that doesn't bring other issues...

Vlado,
thanks for the information. That sounds interesting. But what do you mean with "it's lame"?

[mcnamex]

have u try using fresnel fallof , sub pixel turned on...

Because it produces an image with slightly incorrect brightness, similar to the clamp output option in the color mapping settings. Still it can be quite useful.

Hayy it works! Yea it is different but better that quick fix rather than not having anything for a long time and fireflies everywhere.

Thanks Vlado !

Where/when do we get a 3.x build?
