Hello,

First of all, thank you for sharing these amazing plugins.

I'm experimenting in Maya 2013 with nParticles and Mash and I'm trying to render using Arnold. The problem is that every time it crashes.
I'm thinking that if I can export to a nParticle cache file all the transformations done by Mash to my original particles and passed over to the instancer, I can load that cache into a clean scene and render with Arnold but I haven't found a way yet.
Do you have any suggestions for me?

Best,
Bogdan Toma

Hi Bogdan,

You're welcome!

Caching won't work because the MASH calculations are performed 'downstream' of the nParticles, I would need to write a MASH caching system.

With regards to Arnold, I don't know anything about this renderer sadly, I have only tested MASH with Vray and Mental Ray, so I'm not sure what the problem could be. Is there a crash report you could send me?

Thanks,

Ian

Hello Ian,

I was hoping I could take all the data modified by the MASH nodes and plug it into a new separate nParticleShape.
As for the Arnold renderer, here is the crash repott:

Hi guys!

since I have been using many of Ian's scripts over the last years, I know for sure he is a very hard-working guy, and he is totally devoted to give awesome scripts to the community always for 0$.... Now Mash brings almost everything you want from C4D in maya, this is so coooolll!!!

I think we should focus more on giving feedback to what we have now, (addressing stability issues) instead of asking for new features!...

He could sell Mash for several hundred dollars... Anyway. you don't ask Realflow to produce fire ; )

Maybe we could start a thread for feature suggestions?

Just my opinion! I feel he deserves a little break and a big thank you : )

Sure Rick, I have the same opinion. I wasn't asking for something new, I was just questioning about a workflow, a solution using the already existing nodes.

Thanks Rick/guys for your kind words.

While we are developing this all the time it is an internal project so gets picked up when we have time between jobs and when Ian fancies spending time on it in his own time.

We're really chuffed with the response MASH has had so are keen to push things further and all your feedback is/will be a big part of that. I've created some categories for this forum now so feel free to keep posting into the relevant one.
