On the subject of artificial lighting, is there a way to introduce a 'glow' to the light unit somehow? Something to essentially, mimic a lightbulb.

A couple of versions back there was a way. But at the moment it seems to me there's a bug with having both emissive materials and lights in a scene.

I need to test more to see if that is the case.

But to your bulb appearance query. I couldn't get any shader to respect how light should behave as it passes through a frosted glass. When I did get close the render times weren't worth the effort. It also crashed a few times during testing so that dampens my enthusiasm a tad.

I will try though. Thomas would benefit from seeing where shaders are not doing what is expected from a users point of reference.

@Rich-O-Brien

I was wondering if a different layer may help but going back to renditioner, which had a similar method, it may make no discernable difference.

[Mike Amos]

@Mike-Amos

What I have so far, I placed a flat plain just behind the emitter light (Directional) and reduced the opacity a lot. there is some room for improvement with temp etc but a start.

[Rich O Brien]

@Mike-Amos

Here was a test I did yesterday. The bulb has a Glass shader with Roughness and Transparent Shadows.

Inside I put a Sphere Light. Its not behaving right though. I still believe that lights and the values needed are off.

[pixelcruncher]

@Mike-Amos The missing skirting board and lights, was that caused by a bug in Rayscaper?

[pixelcruncher]

@Mike-Amos

You can use fake emission. - This will give objects a glowy appearance, but they are not really lights, so they won't shine on the surrounding objects. Using the fake emission option will also reduce render times.

In the below image, the left sphere has normal emission and the right sphere has fake emission.

@Rich-O-Brien This looks indeed buggy, thanks for the information and I will look into this problem.

@Bryan-K

Ta mate, feedback always helpful. Building and rendering the scene can lead to missing/ignoring stuff.

I hear ya. Happens to me all the time.

[Bryan K]

Oh that last one is damn good!

[Mike Amos]

@Bryan-K

I have notioced glitching and pixel loss on the monitor but a pixel fitness test proves the monito is fine and the graphics cards GPU is the culprit, probably one of the issues I have had since I got this pc. A nuisance but that's folks life........

[Mike Amos]

My last post was not at anyone, that bleep thing is a pain. Just a cmooent in the thread about the experience of the process of rendering the model. I can no longer render with Rayscaper probably due to the graphics card/gpu. Soon have the beast off for repair though.

[Mike Amos]

@Mike-Amos

Well, the beast has been received at the treatment centre so I am running the old machine, similar size etc so no surprises it looks and smells the same.
The internal dimensions are 12'square for the main rooms with a 5 foot bathroom and entry downstairs.

Entourage and some tweaks are all for the model I think then get some attention to the lighting!

For some reason when selecting gpu render, this pc reverts from 2748 x 1048 to 1000 x 1000 pixel size.

[Mike Amos]

@Mike-Amos

Well, had a thunk to add a reading light over the desk, balance. I still do not have it yet but, I am looking.

Peace out.

Lightened in Irfanview. The original was blurry dark.

[pixelcruncher]

Nice render Mike!

Can you reproduce this consistently? Smells like a bug.

Maybe this is something I can help with? Is the light just not rendering, or are you having trouble configuring the light?

Cheers,
Thomas

[Mike Amos]

@pixelcruncher

Well, difficult to say if there is any illumination from the unit, it has a fake emitter and two directional lights which are pointing in the correct direction. Still getting myself oriented with these lights.

[Mike Amos]

@pixelcruncher

Essentially the balance issues make it difficult for me to see where the illumination level is do I will have to render a scene or two with just the lamps I have made and adjust from there.

[Mike Amos]

@Mike-Amos

Weird this, one spotlight and one directional light along with the fake emitter surface.

I ramped up the directional light alone to 100.00 watts. OK, distance that this illumination appears at needs adjusting. I then reduce the power levels to zero watts and the illumination does not change. I will close Rayscaper and open it again, see what happens.

[Mike Amos]

@Mike-Amos

OK, part of the reasons for a simple black screen rather than a render is that for some reason, there were TWO 'ghost white' textures/colours imported. Only one of which had any reference to 'glass'.

Nice to find that.

Even at 200w the cone of light is not apparent from the now 2 x spotlights.

[Mike Amos]

@Mike-Amos

OK, the properties assigned to materials etc in Rayscaper are not surviving shutdown and restart on this pc. Memory? 32gig and a decent graphics card suggests not.
