Hi, dear developers.

Ornatrix alembic doesn't render in Corona Renderer. =) Please add this feature





Scene -> https://bit.ly/3lUAWK4

Thank you and have a great day
Best regards,
Andrew.

Hi Charly, sorry for the delay.
Unfortunately I will need a bit of help here.

I tried opening your scene and following your steps, and it seems that:
1) The hair does not render at all if the "mesh from strands" modifier is disabled
2) The hair does render fine if the "mesh from strands" modifier is enabled
It is the same with Corona and V-Ray.
I tested with Corona 6 HF1 and the 06.11 daily build, V-Ray 5 HF2, and Ornatrix 6.3.5 and 7.1.0.

My questions:
Is point 1 not expected?
Is point 2 expected?
What exactly is wrong?

Next time, it would be great if you could provide a scene which we can just open, press render, and immediately see the issue. Thanks in advance!

Hi, Maru

No problem =) I just see this message =) Sorry for the delay too =)

So, in V-Ray, I can render this object without MeshFromSTrands and this is the right way. MeshFromSTrands convert all the hair to mesh and as a result, we have polygons, not particles and this will slow down the viewport and the render. Ornatrix particles optimized to render the hair fast and V-Ray supports this. Corona supports an Ornatrix object, but if we will export it to Alembic, V-RAy can render this alembic, but Corona can't. Just only with MeshFromStrands which is bad for speed =)

I can't prepare the Corona Scene, because I haven't a Corona License now =) It expired and I did not renew it, because now I don't use Corona in my projects.

Thank you and have a great day
Best regards,
Andrew.

Hi,

Alembic support for the CoronaProxy object has been requested previously by you: https://forum.corona-renderer.com/index.php?topic=30697.0

It is logged in our system and in our pool of ideas :) however I am unable to give you any timescale on when this might happen.

Just a note, requesting the same thing many times will not speed up the implementation of a feature ;)

Cheers,

Rowan
