Hi,
a few question... but not to bother you it's because I have an open topic on hdrlab

did you just add the new sky parameters and the environment background rotation and mirroring mapping parameters?

Spot, point, LR Sun , LR Sky works.

does this mean that all other lights are no more supported? direct light... & mr
I'm also wondering if the spot light just can export the ies info for Luxrender

[hedphelym]

here's a list of currently working lights:

Omnilight
targetSpot
TargetDirectionallight
LuxSun
LuxSky

did you just add the new sky parameters and the environment background rotation and mirroring mapping parameters?

right now this works just as with the latest c++ plugin, but I can expose all these settings in GUI.

I'm also wondering if the spot light just can export the ies info for Luxrender

Is this when you point to a "IES" file?
If you can give me an example on how it looks in the LXS when a IES is applied then I can do this.

[patro]

here is the code for the light with a ies texture exported from blender with luxblend:

oh yes! and thank you.
I have to edit manually the lxs at time to add the parameters.
do you need the code line for the environment background mapping/rotation/flipping?
here the code lines that Lord shared.

Code: Select all

# rotate image -90 degrees around Z axis
Rotate -90.0  0 0 1
Scale -1 1 1

and here how it looks in the lxs

Code: Select all

WorldBegin

#Env userprop F:\CAD\mappe\hrdi dds\sIBL-Collection\lago_di_garda_low\lago_di_garda_low_Bg.jpg

# Enviromentmap goes here
AttributeBegin

# rotate image -90 degrees around Z axis
Rotate -90.0  0 0 1
Scale -1 1 1

thank you.

so the IES is applied as a texture, that makes it even more easy to implement.
I can make a new texture like I did with the LampSpectrum, then add a "browse"
that you select IES file with.

..........
so the IES is applied as a texture................

I'm not sure about... I hope some one with the knowledge can help you. but it seams that you are right about.... in the blender scene... the ies light is a plane with a light material applied.

by the way... I'm not blender user.... but if you need some lxs code lines exported from it... to better understand how to implement it in 3ds max... please ask

Hi,

No, the IES is an option to the "point" and "area" light sources (parameter "string iesname").

Ok, I will test this when I get home later today.

[hedphelym]

Almost got the normal's working..
Sample:

Also, the IES data, since this is an option for a light, and not a texture I've got to create new lights that
includes this new buttons for selecting IES data file.
This will take a little while, so I won't focus on this right now, more important to get the normals fixed, + all materials.

I'm also almost done with coding in the integrators into camera (Sooo many settings to add..) but it's moving forward.

and one note; the exporter has not crashed 3dsmax a single time.
Just some times outputs an error (obviously since I'm coding on it while testing).
But still - it works great.

Hi all max user.

I posted some info about the recent additions to LuxRender... give a look if you miss.....
