With 2.5 being near release, I assume this will be moved to 2.6.

Could the SDS-cache for BiDir be exposed in BlendLuxCore, please?

Hi, @B.Y.O.B is there a timeline when BlendLuxCore is updated to Blender 2.93?
It will be published next week as far as I know.

Cheers, mib

I know this is not relevant to the thread but I have a simple question is Scene_DefineBlenderMesh define just for a blender in python or it is available in c++ like Scene_DefineMesh too?

Can you open a github issue for it so I don't forget?

It's just for use in the Blender Python addon. I don't think it's callable from the C++ API (and it wouldn't make much sense to use, since it can only convert Blender mesh datastructures to LuxCore meshes).

Was just wondering about one thing :

Is it possible (coding wise ) to optional reshape/resize how the HDRi is seen when rendering ?
I mean maybe you want the environement to look a bit far/smaller. Like you are playing with a sphere dimension on wich the hdri is mapped.

Just put your file on a sun and switch to Hemi ;)

Ctrl+G can't work in luxcore material node to create node group.
Anyone succeed to make it work ?

Re:Improve performance for Render Engines Addons

Post by Sharlybg » Fri Aug 06, 2021 10:48 am

Team
Commissioner: @Brecht Van Lommel (brecht)
Project leader: @Brian Savery (bsavery)
Project members: - Optional other developers, can be in multiple projects at once.

Description
Big picture: There are certain issues external renderers working with Blender have that Cycles does not due to it's access to the blender C data structures. Render Engine Addons have to work through the Python API and thus have limited performance. This "TODO" will include various subtasks for improving the render engine interface.

Use cases: Or possible things that could be improved

Faster reading of mesh vertices (as numpy array?)
Faster reading of hair or paritcles rather than using particle_system.co_hair(...)
Pre-load image data so that image.pixels.foreach_get() is not blocking. (see https://devtalk.blender.org/t/render-en ... ce/19251/9)
Detecting deleted objects?
Branch: - Existing patches or branches.
