Cinerender - Light Settings removing light artifacts

[Anonymous]

I am confused on how to remove artifacts from the Fluorescent Lamp 19.

I am trying to understand how this one light fixture works so I can get rid of artifacts. If I apply AIR surface to Light fixture and move it down into the space there are not artifacts?

When I was testing the Fluorescent light fixture, the object was creating the light in the renderings.

In order to use an IES light you need to place another object that will generate the light.

So if you have two light objects one should be off, otherwise you have duplicated lights. So when I want to see the IES light the other light needs to be turned off.

I don't understand.
What do you mean exactly?

I'll try.
Can you share the settings of cinerender, please?

With your tests I got a little bit more confidenti with Cinerender (I've been using Maxwell and Artlantis). Cinerender is a good improvement in the workflow. It allows you to not waste time with settings and corrections outside the model in archicad ...
On the other hand ... well ... I need to improve my skills ... with tests tests and tests ...

I did some tests.
This is what I got (see the attached picture). It is the preview image but the final one is not so different from that one in terms of artifacts and general result.

I passed to AC19 from AC18.

IES are ok.
Materials with luminance (I put a square downward with a luminance material for each lantern) produce yet so many artifacts.

How to avoid those artifacts?
What's the parameter to play with in order to have a more decent light distribution from luminance materials? Is the AREA SAMPLING parameter?

Interior Renderings and Exterior Renderings will always have different settings in order to optimize speed and quality.

In Terms of the Artifacts I found that the fluorescent light created Artifacts. There are other ways that artifacts can be created depending on the surface and other settings.

Still trying things out so I am not certain I can point you in the right direction.

However these two threads are very useful for me at the moment.

If you have a better image of your rendering to upload, it would help to see what is going on with the lights.

Also try doing a white model rendering, turns off surfaces to plain color and see if you still get artifacts. If you do not have any artifacts that probably means it probably has to do with some surfaces settings?
