v3 not exporting Alembic or ORBX from v2 file

I have a v2 Octane Blender file that is not exporting correctly using the latest 3.03.4 - 11.5 version. Only first frame appears to be exporting (can not tell for sure because animation starts at frame 0 with no geometry initially present). Also no timeline slider appears when the Alembic or ORBX files are imported into SA.

This very same file exports perfectly to Alembic and ORBX under 3.03.4 - 11.2. The issue appears to have occurred only with the change in moving these export features into the main Blender export dialogue box.

Blend file attached.

Thank you for report. I see it is some regression especially with "Curve" objects... Will check it.

Fixed in 11.6.

Thanks for the quick fix JimStar!

Curve Modifier Export to Octane Alembic

Hi there.

I've been using Octane with blender for about 5 years and suddenly found a strange issue. Here's probably one of the most simpliest scenes ever: a curve and a box with the Curve modifier (I also have a camera here, but it is not about that).

When I render this via Blender ot os ok, but if I export this to "Octane alembic", I do not have any mesh deformation animation (only simple translation movement). I tried to use both "Reshapable proxy" and "Global" mesh types, the result is always the same.

Tell me: should I laugh or cry? :)

Does the plugin support modifiers? I'm not sure, but you might have to apply the modifier before exporting?

Apply before exporting? It isn't a solution — I need an animation. Modifier causes it. If I apply it I will get a static mesh.

Update: I tried to use standard alembic exporter and it gave me the same result until I set Transform and Geometry Samples to a values > 1. After that standard blender alembic exporter gave me a file with animation. But standard alembic exporter seems almost unusable for complex scenes.

Looks like it still broken. :(

I've described it here viewtopic.php?f=32&t=57239&p=294023 and now I can provide some additional details that I have found out while testing the issue:
  1. If I open old scene and don't make any change (I used scenes that I did for this video, so they are pretty complex) — just use "Export Octane alembic" option, it exports just fine — all animations are correct and present.
  2. If I make any change in my old scene then in exported scene I have no single deformation animation (i. e. Mesh deform, Curve, etc.) or rigging animation — only translation, scaling and rotation changes.
  3. Mesh type and number of modifiers don't affect this.
  4. This issue is also correct for the standard alembic exporter (until I set more samples as I described in my topic) and standard FBX exporter too.

If any Blender's internal exporter behaves the same way - this is likely Blender's issue, not Octane's. But I will check it on Monday, perhaps some workaround is possible...
It's different to the one fixed before - previous one was clearly a regression in plugin code, and it has been fixed.
Could you share the scene?

Yep, I googled for the similar problems - seems like it's some blender internal problem — some effects aren't teansfered to export engine... Is it possible to return the old method of export? Via render button? :)
