Indigo Renderer Forum

Hi All,

I'm pleased to announce a major new version of SkIndigo, with some major architectural changes, and large performance increases!

We have spent the last week or so revising the core scene traversal and export code, making the export more modern.
This has allowed some major speed improvements, especially for subsequent exports of a scene.

Some long-standing issues have also been fixed.


Some measurements of export time for a mid-sized scene:
Old SkIndigo version (3.6.28.3):
Initial export time: about 20s
Subsequent export time: about 19s

New SkIndigo version (3.8.6.1):
Initial export time: 22s
Subsequent export time: 1.32 s

Note that the export time for subsequent exports has been reduced from 19 s to 1.32 s, that's a ~14x speedup!


Because so much code has changed, there will inevitably be some new bugs introduced.
Just let us know about them in this thread and we'll fix them ASAP.


Full changelog:
Minimum required Indigo version is 3.8.5.

RBZ: (Works on all platforms)
http://downloads.indigorenderer.com/dis ... .8.6.1.rbz

Windows Installer:

EDIT: updated in place with hopeful syntax fix, and:
Rewrote mesh processing and export, a lot faster now. Only one UV set supported currently.

So... anyone tried it?

I get this on Sketchup startup after installing new Skindigo:

I'm on SU 8 if that makes any difference...

Why such an old version?

Voytech, bubs: please download and try again. Cheers.

I'm just lazy...

Thanks for the update I'll give it a try now.

Tried it on just the plain empty scene with susan, and it exported OK but all the diffuse mats seemed to inverted in colour...

I then tried opening an existing scene and got this;

An error occurred while SkIndigo was exporting the scene.

Hi bubs, this might be a caching issue. Can you please try this:
Open up a command prompt (Start -> type "cmd")
cd into your temp directory, e.g.

cd C:\Users\nick\AppData\Local\Temp

then type

del *.igmesh

And then try re-exporting the scene.

Yeah that worked for the colours on the default model but I still can't export from existing models...

I have updated the builds in-place.
Bubs: please re-download and try again.

Still no joy I'm afraid:

Hi bubs, can you send me the scene you're testing with?

Have updated builds with some fixes.
