Title: Light select pass - add environment override checkbox option
Post by: shiftman2012 on 2016-09-08, 10:02:21
I would like to request to add  Corona environment override check box in Corona light select pass render element.

To use 2 variants of environment light in light mixer. One for 3ds max environment slot, and one for corona environment override. This is important because this lets create day and evening visualisations in one rendering.  Environment for daylight (sky), and corona environment override for evening, night visualisations.

This would be impossible to do internally, and would also lead to very clumsy hack-ish workflow, so it wont be implemented. We might just try to separate light contribution and direct visibility of environment

Sad to hear it. Can you explain what results will give light contribution and direct visibility override separation? Will it give option to use to environment variants?

Both in exterior and interior, at night rendering it is used one environment together with other exterior lights, and for day lightning it is used another environment( sk or hdri).

It is difficult to understand to me how to do it, but maybe it is posibble somehow to do.

I saw your presentation of light mix, and night rendering it lacks environment, because day hdri is turned off. And first question was will there be option to use environment. Then i thought it is needed 2 variants of environment.

So we can not use light mix to do evening and daylight in one render, so it is limited , and can be used only for change light  strenght. People think that it is very cool to have two versions of rendering but it is not possible.

maybe it would be possible to do if corona would have dome light. so it can be added to light select, and there would be to variants of lightning including environment.

There should be way to do this, so it is theoretically possible to do. Or i am wrong?

it is interesting to know if maxwell renderer is able to render two different environments and mix them ?

it seems that maxwell can use only one environment, and night render is no environment light,just black. Sad.

I think dome light should do the trick. But it would:
a) impact rendering speed
b) make the regular beauty pass unusable

everything is posible.   but it is now imposible with current knowledge and technology. maybe in future this barier could be overcomed.

now light mixer is intended to correct light intensities and colours on the fly while rendering. it is verry good.
