AC 20 lights not working

Anonymous — Thu, 11 May 2023 09:40:25 GMT

Spotlight 20 and the bar light are working okay, but I can't get Halogen Recessed 20, spotlight ceiling 20 & spotlight wall 20 to produce light. Have spent almost 2 hours today trying and checking every
setting I can find on these both in CineRender. Has anyone had this problem with these? Under the spotlight wall and halogen there are what looks like large snow flakes, but no light on the surfaces.

Thanks for any help on this.

Jonathan:

Are the lights recessed into the ceiling? If so, you will need to create holes in the ceilings for the lights.

You can also use the fixtures for 3D model and use the spot light / IES light which has more options for lighting to begin with.

If you are not too fussed about the actual light coming from them, you can even just chuck a general light with unlimited strength in there to light the whole scene.

Setting up interior lighting for a render can start taking up quite some time and if you take in account that most nice photographs in magazines are using extra lights to light the scene, you start to appreciate that having 'just' the actual light fixtures might not sell the scene to your client.

If it's a quick 'fake' you're after, you can put some glowing surface on the lightbulb/source (remember to enable glow in cinerender) and combine it with the general light.

There are a view video tutorials from ArchiCAD18 for interior renders and even some .pla files you can download that go with them so you can see how they set stuff up.

Hi David,

No Holes yet. I have placed the entire fixture below the ceiling first just to
see what kind of light settings there are out of the box. No light!

Here is a picture of what I'm running into. 3 lighting types not working! instead of lighting the surfaces they are producing strange spots and snowflake like things.

Since your image has the green arrow, I am guessing that this is the PhotoRender Preview, not an actual photorender. The Previews are not perfect, so try an actual photorender to see the result. You can also post a screen shot of the Lamp Settings > Light Settings for the Lamps that are not working, as well as the name of the Scene you are using, and someone may spot the issue.
