BlendLuxCore Development

[B.Y.O.B.]

Yes, that's possible. It's already there in LuxCore, we just have to use it in the addon.

Basic AOVs are now in master.
Todo: https://github.com/LuxCoreRender/BlendLuxCore/issues/18

[B.Y.O.B.]

I'm currently implementing a faster AOV import routine in C++.
Managed to get the import time of the RGB AOV from around 0.7 seconds down to 0.005 seconds

[B.Y.O.B.]

Results of the framebuffer acceleration (importing one RGB pass with 1920x1080 pixels):

Before:

Code: Select all

FrameBuffer draw took 1.841s
FrameBuffer draw took 1.744s
FrameBuffer draw took 1.378s
FrameBuffer draw took 1.604s

Now:

Code: Select all

FrameBuffer draw took 0.493s
FrameBuffer draw took 0.358s
FrameBuffer draw took 0.320s
FrameBuffer draw took 0.328s

About 0.3 seconds of each measurement are caused by engine.end_result(result). I don't think we can optimize this because it's a Blender function.
The accelerated C++ function accounts for about 0.07 seconds of the time in the new measurements.

Is DEPTH AOVs enabled by default ? I have seen it enabled in a couple of scene I have loaded today

[B.Y.O.B.]

Yes, because it is enabled in Blender by default (in Cycles it's the same).
It probably should not be, but if I don't enable it by default, there is a black "Depth" pass in the render result. I can't remove it unfortunately.
However if you think it costs too much RAM or so I can disable it by default and we just have to live with the black "Depth" pass.

It costs both a bit of ram and performance, not a big deal but it looks like a waste.

[B.Y.O.B.]

I found a way to disable Blender's Z-pass by default, so the problem is now solved and the DEPTH AOV is disabled by default

@Simon

You run into trouble using:

Code: Select all

from enum import Flag, auto

Flag is an python 3.6 feature but next blender will stay with py 3.5 afaik.

Verify by testing in master ( py 3.6 ) vs. 2.79_rc latest src ( 3.5 )

[B.Y.O.B.]

Damn it. I actually checked if it was supported, but I used the wrong Blender version by mistake.
Thanks, I'll revert it.
