lightMesh & LightMTL not working always

[ricorio]

Hi,

I have a outdoor night scene with about 500 candles.
The candles flame has a light mesh aplied.
Now when the camera moves out (while the candles form a logo) some lights get rendered ... others not.
The light that get rendered one frame dont get rendered in an other. So the rendering of the candle flames is completely random.
I also tried a lightMTL ... same thing. The candle flames are tiny. Scaling them about 5 times bigger the flames get rendered every frame.
Although scaling of the flames is not an option.

Setting the render res from 1080p to double the size all flames are visible.

How can I solve this? Im working in meter units.
The Scene with the right scale is here: www.cgillusion.de/lightingTest.mb

cheers

Okay ... the scene with ONLY the flames mesh has the problems of getting randomly rendered.
With some GEO to let the light shine onto they all get always rendered like expected.
Straaaange ...

Hi,

Could it be that your sampling settings are low and V-Ray is not hitting the lights?
Can you show an image?

Hi Teodor,

the sample should be ok ... I think.
adaptive dmc 1 / 7 / 0.008



I don't have any 'failed images' anymore.
