I want to say thank you for the extraordinary oportunity represented
by Houdini Indie, 8) and I am considering to purchase it soon.
I am a 3ds max user, but I've always wanted to make the jump to Houdini
and I've used every oportunity to learn it.
My main concerns :
Still have some doubts about resolution and Import/export capabilities:

1) The 1920x1080 limitation for mantra is the single point that stroke me
as a bit unfair, because even Broadcast today is 4K for Vídeo ,Hope Side Effects will make 2K the indie standart in the future.
yet I am outputing for 2K , but hope that for Ocean FX simulations
renderings 1920x1080 will be enough to resize and comp with my 2k footage
in After effects, considering that CG is a really more defined in most cases.
Am I right ?
2) Considering that Houdini Indie do have Alembic and FBX support,
would be possible to export my work to 3ds Max 2015 ? and maybe render the exported files using Vray , Octane or whatever the renderer I choose? Does it help if I acquire Houdini engine for 3ds max ?
Does it aplly for particle simulations like ocean FX ?
I am also a licensed user of Clarisse FX.

I'd apreciate any clarification of those , for me, crucial doubts.

1/ Not sure where in the world 4k is the standard for broadcast. 4k is normally for acquisition and output is HD. Most films are 2k or 3k.

2/ yep - simply export and use in any program

1)Thanks for your reply.
USA …..?
2)awesome.

Seriously? My mistake then. Would have thought 4k broadcast and TV's marketplace penetration are too small to force 4k as a standard broadcast.

Out of interest how many commercials are finished at 4k in the USA compared to HD?

True.
No, I think you are right, actually.
Full HD 1920X1080 render plates will be enough for my 2K project.
I apreciated your help ,and I am looking forward to try
Houdini Indie.
