Is there a limit on Lightmix elements

[Jpjapers]

A Colleague of mine mentioned he had a message pop up saying that his render may be slow if a certain amount of lightmix elements were used.
Is there an actual limit to the amount or is it just however much data your ram can hold?

Thanks

no hard limit, it will just get slower and take more RAM

This might have been requested already, but can you make it automatically group instanced lights per element when you hit the button? Or have two buttons, one that treats them as unique and one that doesn't? This would save a huge amount of time.

Yes, this already has been requested:

changing the behaviour of that one button only though.

Ok cool, is it the amount of lights or the amount of render elements that slows it down?
There could be a couple of hundred lights but only maybe 10-15 lightmix groups.
The machine has 128GB of ECC RAM so i dont think ill have a problem but i want to be sure before i tell my boss i can actually do the project!

Thaaaaaanks :)

Just to be sure:

that his render may be slow if a certain amount of lightmix elements were used.

You mean actually "LightSelect" not "LightMix" render elements here, don´t you? I don´t want to be pedantic but this reads as if it makes any sense to have multiple LightMix elements currently and I´m wondering if I missed something. And I´m very skilled in missunderstanding posts at the moment :)

the speed is dependent on number of separate LightSelect elements, regardless of number of lights included in them. Number of LightMix elements does not matter - there is zero overhead in CPU and memory for any number of LightMix elements in Corona (3dsmax will allocate a separate frame buffer for each of them though on render end)

My bad yes thats exactly what i meant. Right ill give it a shot and see what happens :) Should be a fun project. I have a complete supermarket revit model including site to do an overview for with lightmixing. Im actually pretty excited to see how it turns out!

Hehe, understood. I always wear some transfigured, colleague-irritating smile when using the LightMix spinners :) It´s fun for itself.
