I am a newbie and am sorry that my explanation does not have technical terms :. Note: This applies to lamps and objects that have an emission shader. If it is an object, you will need to scale it up literally by using scale in object or edit mode.

Because your scene is not enclosed, adjusting the size of the light might not matter to you. However, if this was inside an enclosed room, and your light had to be constrained to a certain size, I am not sure how to fix it. The above methods should be tried. Adjusting this will definitely help, even though it will decrease the accuracy of the glossy shader Sign up to join this community. The best answers are voted up and rise to the top.

Esanti asked me to reopen the discusion about the "ghosts" white dots and spots that apear sometimes in our renders when i asked him how to get rid of them in a particular scene that i was working on At the beginning in the vray world, i read something that i didnt understand and didnt believed: every scene is different.

Sometimes i thought it was a lie, but I must admit that it is not. Every artist have his work method, some preffer modeling everithing, some preffer to use more the displacement modifier Coming back in the white dots and spots, the truth is that there is lot of answers too.

Could be the hdri map used, the subdivision used in the light cahce, the antialiasing filter used, the min and max used in the Adaptive DMC sampler, or even the Adaptive amount and the Noise threshold in the DMC Sampler. But one of the fastest way sometimes, not in all the scenes is to use the Sub-pixel mapping and the Clamp out in the Color mapping All opinions are wellcome Joined: Dec 11, Messages: 63 Likes Received: 0. Thank You for starting this topic. I do not have an answer to the problem but I do rarely run into the 1 pixel white dots.

To know more about these 2 important parameters, here is the official description from Chaosgroup:. Hemispheric subdivs HSph. Smaller values make things faster, but may produce blotchy result.

Higher values produce smoother images. Note that this is not the actual number of rays that will be traced. Interpolation samples : this is the number of GI samples that will be used to interpolate the indirect illumination at a given point.

Larger values tend to blur the detail in GI although the result will be smoother. I have always found very useful tips on CG Blog……. Thanks a ton. I am saving so I can sometime purchase the full tutorials. Can I ask what resolution you are rendering at here.

Ciro Sannino - Auth says:. Dave Buckley says:. October 23, at pm. Amal says:. SONI says:. Juan Milanese says:.Setting the perfect white balance while rendering has always been a tricky affair. What makes it even more difficult is our own aesthetic perception. Should it look a bit more cool or warm? Judging your own eyes becomes a bit deceiving. The objective is to make sure that what looks white in real life, also gets rendered as that same white in the photo.

Incorrect white balance introduces a color tint, usually blue or yellow, to your images. So what can we do to remove all the hassles and set a perfect white balance in VRay? Discussed within this book, was a technique involving the use of perfectly white or grey balls, photographed in the same environment, to be used as a reference. The principle behind this technique is to identify areas in your image that are supposed to look precisely white or grey, then using those areas as reference for the tint removal process.

Based on this same principle, there are a variety of techniques that accomplish the same task, but this method is by far the easiest and effective. Alternatively, you can even use white balance as a creative tool to make filter effects like midnight blue or noon yellow.

This can help you to achieve deep blue night skies or a hot noon sun. Make sure your display is correctly calibrated to a standard k color temperature. Otherwise, this will adversely affect your white balance. If you found this tip helpful, you can be sure to find plenty more on my site. Talk to you later, guys.

Now to set up your DMC sampler settings. This is going to show you a heat map of how much work your DMC sampler has to do. You'll get this, basically you want your image sampler to work less and only in the right places. Firstly increase your high subdiv number to 24 i'll explain in a second you can make it work less by increasing the threshold number from 0.

This number controls the difference between each pixel. I can guess that your sample rate render element will be mostly red where as you want it like the image above, only red on the extreme contrast spots. Those red spots are so you how many samples it's using to clean up your image, for example the red spots are using the highest number you set 24 and the blue will be using the lowest 1 since we added a number of 24 your going to have 24 colors going from blue to red in your sample rate render element.
