Hey there, I am trying to lerp two normal maps. Not combine, but lerp / mix. Unfortunately the Color Math in BlendLuxCore doesn't support it, it says Wrong Input. Is there a way to do the normal map conversion later in the node tree and not in the Image node, so I can do normal maps operations? Than...

It only happens with LuxCore, changing the exposure thinks the World Light has changed: [Exporter] Update because of: OBJECT | REQUIRES_SCENE_EDIT | WORLD [SDL][444.500] Light definition: 2663798522552 [SDL][444.500] Light re-definition: __WORLD_BACKGROUND_LIGHT__ But it doesn't do it in new scenes....

It looks like it works fine when using the GPU.

EDIT: But it's not the only reason, I have old scenes that would refresh the render for all changes even GPU. Copying content to a new scene seems to work. I wonder what saved setting might cause that.

Hi there, I am trying to understand why in Blender, the viewport render gets refreshed when changing the Color Management Exposure or curves. I thought it was "just the way it works" as it always happened in my previous scenes, until I noticed that it wasn't doing it in a new scene. Is the...

Such a long changelist, you guys are amazing.

New version is here: https://gumroad.com/products/cQTgl/

The other link in the first post is the older free version 2.

When Photographer 3 was released, Physical Lights were not supported for LuxCore, this is why it's not visible in the video. BlendLuxCore already has Physical Lights units, I added them for 2.3. Photographer users wanted to be able to switch between Cycles and LuxCore and keep the same lighting, so ...

Awesome helper B.Y.O.B.!

Can't remember if I asked already, but would it be possible to make all the render print optional? When working on addons, it's a bit annoying to have it writing constantly in the console during viewport render. It's probably affecting viewport performance as well.

Adding a normalize flag it is pretty much trivial. The IES map is always transformed in an image map: https://github.com/LuxCoreRender/LuxCore/blob/ac9b4898d2b9377f45b7da8c9c454fb6903668a8/src/slg/scene/parselights.cpp#L109 It is about adding here 3 lines of code to normalize the image map pixels: ...

Would it be possible to add support to use IES as masks, i.e. normalizing the embedded light intensity so it can work with regular light intensities, or to use the IES profile intensity?
