LuxCoreRender Forums

Hi,

I'm testing the sanity of new lux core. I'm trying to use a real world dimensioned LED light source (modeled from OSRAM datasheet type LTRB GFSF).
This light source emits red, green and blue light, each from an individual chip. Unfortunatly I don't know how to attach a spectrum in new lux core.
The classic lux offers the "tabulated data" texture for this tasks.
To receive any kind of result I've used RGB values to describe the color of each chip.
First render test is a clear PMMA volume (n=1,492 - no dispersion) guide that is swept in a rectangular profile.
The back-surface contains a rough glass definiton (0,33) - all the other faces are perfectly clear.
The camera is set to linear tone mapping.
Watching an intermediate result (after 1 day) shows that it may has some over exposure. Is it possible to adjust camera settings while rendering (like in classic UI)
Actually I've expected to see some non mixed colors at the very beginning of the pipe.
I don't know whether its the missing spectrum or the camera settings.

Yes. Just edit the camera imagepipeline settings in the usual place.
You may have to leave the full-screen image editor first with Ctrl+Down (down arrow on keyboard) or by using the "Back to Previous" button: The render will continue and you can go to the camera settings and adjust settings.

Hi,

That's easy... and perfectly working! Is there also a way to save the rendering like an *.flm file before.

Found my color mixing issue also. BR

It may be more useful to save a .rsm too (a file to resume the rendering with LuxCoreUI)

Agreed! Is it possible to save such an resume file within Blender?
If yes, where do I find that option?

It is not yet possible in the addon.
I started to work on it in a branch a while ago, but I ran into problems.
I will need some time to document my issues, then I will report them.

No worries.
Take your time.
Thanks to all of your support.
