Yes, we will not forget it. We just want to do it right, which takes a bit longer.

Power is approximately in Watt.

Wouldnt it be better to use lumen instead? You've gone from Lux to watt instead of Lux to lumen which is in this case the corresponding SI unit. Watt is more or less unrelevant in this "LED" fixture days

The luminous efficacy of a light source is defined as the ratio of the total luminous flux (in lumens) to the total power input (in watts).

the smaller the size of the light, the longer it has to wait an adequate caustic.
with a very small lamp, which gives a clear shadow, instead of the caustic is only a little white dots, no matter how much time was not going to render.

hi there,
what about this issue regarding the expanding of all nodes (e.g. http://www.refractivesoftware.com/forum ... 397#p49397) ??

wouldnt it be great to add some bugtracker where all licensed customers can post bugs. ->the customer could see the status of the bugfixing or if any workaround is know to avoid this problems.
additionally some feature request thing like blenderstorm.org would keep the forum better sorted.

cheers dave

hi, i think there is something wrong between the actual light that an object emits and the brightness of the surface. look at the image attached. the ceiling lights emit quite much (efficiency set to 1) and power near the max.. but the mesh itself is too dark

any idea?

cheers,

I have seen this too, but if you fiddle with the float image scale you will see the bright stripe of the image (or .ies) come into place, just like it would if it were a texture bitmap being scaled onto the surface

Are you using a distribution texture? If you do, the brightness of the emitter is dependent on the viewing angle.
