Maxwell Render | Official public forum

Modeling is not complete, but thought I should run a test render as I expected "issues". Chandelier is placed in a box about the size of a room. Only illumination is from the lights which are an emitter assigned to the light bulb geometry. Gold and (crystal) glass were downloaded from the MXM site. the major issues:
1) Purple arrow: lots of light dots flying around that will likely never clear up. Must resolve this.
2) Benchmark of 33
3) Red arrows: Black balls at the ends of the light fixture arms should be glass (see green arrow).
Chandelier will be viewed from approx 3 to 4 meters.
Any suggestions would be appreciated.

Are the emitters behind glass bulbs?

Try using wizard gold and glass.

it looks like dots are result of caustics. Small light sources close to quite heavy geometry with shiny metal. Just for testing try to replace gold and You'll see if this is reason. Glass balls are maybe refracting black hole in the tube. Aren't they duplicated?

No, I assigned an emitter MXM to the glass bulbs.

Will do.

I ran a quick test with a simple diffuse material in lieu of the gold. It's the gold that was causing the caustics, so will now go back to Bubbaloo's suggestion to use the wizard for the gold...have to be careful about dowloaded mxm's. Hah! I see also no more black crystal balls! So the love of gold was my problem all the time Also, the benchmark is much improved, running in the 130's right now.
Sure would like to do something better with the light bulbs...I like the clear glass ones...but that runs me into what Tom asked about...the emitter behind glass. Maybe I could do an emitter behind AGS glass?

Yes, you should try it.

This is quite challenging. It's interesting that I'm not able to get even a digital picture of what my eyes see...it's not even the same thing. I tried an emitter-filament inside an AGS light bulb...no good. So will have to get creative with this to simulate what the eye sees.

This is what I've got going so far with the light bulbs. They'll be seen from a distance so I think will be ok. The only problem I'm having at the moment is the little glass base inside is rendering black. I used the wizard to make low grade glass. I will try it too making that AGS, but would like to know why it's rendering black and not as clear glass. Joe
