LuxCoreRender Forums

The new addon now has enough features to replicate my wallpaper scene.
Here's a quick render (7min Bidir on my laptop):

Looking good

Hummm very interesting. your final render on old forum turn around 3hr. i wonder how the new luxcore/blendluxcore combo outperform the old one on same hardware ?

The rendering speed will be about the same, as far as I know there were only small speed improvements in LuxCore code since I rendered the old scene.

There has been some major change/improvement in the OpenCL code but you are using BiDir so it is CPU-only. The only difference is likely to be the Embree version.

I have been trying to get a grip on the code but it has been difficult. I managed to get velvet working but I have no idea what I did
But it will come to me, it just requires a lot of practice.
I found it very surprising that I did not have to do anything about saving/loading the blend files. I tried saving it, thinking it will crash when I load the file next time but no, the node was there. Weird but good.
I still want to poke around more before asking any questions though.

Yes, this is not a beginner project. As a newcomer you will stumble about advanced Python and programming concepts here and there.
I appreciate that you try to learn everything by yourself, but please don't hesitate to ask questions when it gets frustrating. We can also talk about IRC/Skype/Teamviewer etc. if you want.
Before beginning serious work on BlendLuxCore you should do a few lectures of some Python beginner course and maybe write a few small Blender scripts or addons.

That's a nice start. If you push the code to your forked repository I can take a look at it and maybe add a comment here or there.

That's handled by Blender thankfully. We have to register our properties from the bpy.props module (e.g. bpy.props.IntProperty() for a number) and the saving/loading is then handled by Blender in the background.

btw I moved some posts to a dedicated topic on compiling on windows: viewtopic.php?f=5&t=20&p=325

Dispersion should now work properly, even with textured IOR, by using an add texture in the background to do the RGB spread.

I added a pointer node which allows to include any material or texture node tree as a node.
This is useful to avoid node tree duplication: E.g. if you have a complex texture setup, you don't have to copy it if you want to use it in several different material node trees. It's a bit like instancing.

I also added Texture node trees.

I improved the error log. Most missing image maps, missing IES files etc. are now reported as warnings.
Critical exceptions that cause the render to abort show up under "errors".
