ply2vrmesh and sequences

Deadline
1

Whats the method for processing an alembic sequence with the submission script for ply2vrmesh? It doesn’t seem to acknowledge the existence of a sequence by default and there is no frame range attribute in the submission dialog. I tried using filename_#####.abc but it didn’t like that either.

thank you,

I am going to be honest here, I know very little about this type of submission, nor the limitations on what we can send via command line to run the render. Can you advise what command line flags are available for something like this?

ply2vrmesh is a chaos group tool for converting a number of cached geometry formats into vray’s vrmesh proxy format. I’ve saved a meshed hybrido fluid in real flow to a sequence of alembic files.

The ply2vrmesh can use a number of switches such as -velocityAttrName (name of velocity channel, default is v). In the case of the alembic files I have the name of the velocity channel is velocities. So i use the following
-velocityAttrName velocities

I’m also forcing a smoothing angle using -smoothingAngle 90.00

now in deadline i can use the submission script outlined here

thinkboxsoftware.com/deadline-6-ply2vrmesh/

so i can avoid doing it in a command line window

but I can’t figure out how to do a sequence. It will only do one at a time.

thanks,

These are all

Hi,
This is an oversight in our current implementation and we should look at supporting an arbitrary frame sequence of geo files for submission and translation via Deadline.

Would you want the “input” geo files to all be merged into 1 “output” file OR are you expecting a 1:1 geo file ratio of input to output files being translated? OR do you want both options?!

Also, is there any further workflow / functionality you were considering when using this tool? (As now is a good time for me to capture this insight and look at it in the future development) :slight_smile:

Thanks for the feedback and I will now log this as a feature request for a future version.

Regards,
Mike

Thanks for getting back to me on this issue.

With regard to whether I would want to combine the input files into one vrmesh or do a 1:1 conversion my preference would be the 1:1 conversion. But having the option to do both would be good.

Other than that I don’t think there is anything else I would need from this tool. It seems like you’ve covered all the options the command line executable has to offer.

Thanks.

Cool. Thanks for the reply. It has now been logged for a future version.
