The cylindrical projection will project the UV coordinates on the mantle of a cylinder. It will not do any special projection on the top and bottom of a cylinder. It also projects from the origin. If the object is not centered around the origin, you have to go to the transform input of the cylindrical projection and change the translation (T) to a point inside the object. Also check if the coordinate space is set to Object space.

Yup better speed now... No more mining for bitcoin at work Roeland

Right click & choose GEOMETRY/MESH import rather than SCENE (scene is for Amlebic import) and you will see that you still can

Uhm, sorry if I sound daft, but ... right click where?

Thanks Roeland.

PS. Can we have such info in Octane - e.g. when we hover over the cylindrical projection node some help/useful info appears?

QUESTIONS regarding performance of Real Time Animation Scrubbing.

I'm testing Alembic import in preview 1.27 - very excited about this feature.

However, animation scrubbing for me is frustratingly slow - it takes several seconds for each new frame to update on models of 16,00 polygons / 33,000 tries or more. Is this normal for my system or do I need substantially grater specs?

I only tested this on the Mac side so far (OS X 10.8.4)

3.5 Ghz Intel i7-3770K
16 GB RAM
GTX 770 4 GB
GTX 570 2.5 GB

Viewport speed while manipulating objects is perfectly smooth at 1024 x 512 resolution & no subsampling. But the animation scrubber does not update for around 3 - 6 seconds (depending upon size of mesh). Even if I disable my GTX 570 from rendering and use it only for display and drop down subsampling to 4 the scrubber still takes the same amount of time to update between frames.

Is this expected behavior for my specs?

If so, what would be needed for the kind of real time scrubbing depicted in the preview videos?

Will the final 1.5 release of Octane have more optimized animation scrubbing that will better work with my current specs?

Below are some tests I did with different mesh sizes. I also downloaded the trial version of CronoSculpt, which has some Alembic files to test with. Below are my results:

Using a simple sphere with some morph animations:

512 polys /960 tris
Time between frame scrubs: instant

16,900 polys / 33,540 tris
Time between frame scrubs: 1 sec.

269,360 polys / 538,720 tris
Time between frame scrubs: 5-6 sec.

===================
Cronosculpt test content from the "Organic Content" folder:

AlienEmissary_Talking
772,816 tris
Time between frame scrubs: 5 sec.

SpiderWalk
785,376 tris
Time between frame scrubs: 6 sec.
