Beta 2.2 RC1: SoftImage XSI plugin testing thread

[adrencg]

I remember seeing something about someone getting strands to render in Octane(can't find it now). But is that just instanced objects with strands, or can it render the actual strand geometry?

Use a instance shape as geometry input.
The result isn´t perfect but better than the Softimage one, when you render instance geometry as strands in MentalRay...

Some good news with the export speed I think

Here are some results...

Test with a 1.000.000 triangle sphere.
Export from Softimage.
Old:
untextured ~35 sec.
textured ~40 sec.

New:
untextured 16.6 sec.
textured 22.8 sec.

Import in Octane:
untextured 22sec + 15sec voxelizing.
textured 33sec + 17sec voxelizing.

Test with 50.000 cubes.
Old export from Softimage, ~79sec.
New export from Softimage, 22sec.

Import in Octane, 20sec + 5sec voxelizing.

Have found that the most time is spent in the conversation from values to strings.
Without the conversation, i can export in the half time, without any values
Have also found, that many small objects needs more time as one big object.
Also a multithreaded version make no sense on many small objects, maybe on a big one...

In the link, that are postet from jamnique, Silo uses << endl to begin a new line. The programmer uses \n to make the same and save with that the time.
I don´t use it, so the time i saved with stdio to iostreams is nearby 0...

He has an exporttime from 1.3-1.4 sec on Silo with a 50k poly mesh, i don´t know if quads or tris.
I have 0.8 - 0.9 with 100k tris

For PointClouds, I write for every point a new mesh. if I make one mesh, it should be faster, will test it now

Ok...
Test 83.333 textured cubes ~1mio tris, they are ever textured.
Export time is now 25sec. 2sec more that a textured sphere with 1mio tris.

I think thats ok...

I think transfer time is the big killer now for animation. It's great that you're making progress with it. I can't tell you how frustrating it is to know that Octane is rendering 300 frames of animation at 1 minute per frame, but it crunches for 4 minutes before it even starts rendering.

[jamnique]

Wow great news! It means my rendertimes will go down twice Thanks!

[adrencg]

Face, do you have a preview version of the XSI plugin with the new conversion speeds, or is it coming soon?

[PeterCGS]

Wow! Great speed increases I do animations with 30.000+ spheres.. Takes forever to export... Cross my finger for a updated plug-in pretty soon

[face]

Coming soon with lights as geo export...

Sweet!

Does the import go faster aswell? (Couldn't make out what was new/old import times from your previous post)... Im at 90+ seconds on export now:(
