Infinite oceans in Redshift?

Hello everyone, I was wondering if there was news on rendering infinite oceans on other render engine than Mantra, namely Redshift, or is it still a Mantra thing and the only option that remains is to export a bunch of maps to apply as displacement on a plane?

Thanks in advance for any replies.

Redshift cannot read the Spectra directly like Mantra can. So, you still have to export the deformed mesh and displacement map (both per-frame) for rendering in Redshift.

What you lose in storage cost you gain in per-frame rendertime.

Thanks for the reply, storage is cheap, not really a concern, just not sure how to make this work, especially with flip fluid integration, like an infinite ocean with a boat roaming through the ocean, is the visual quality as good, do I need to export huge maps, etc.

Here is what I want to achieve, I gave up on rendering this in Mantra, takes days on my I7!

Yeah, there's already been alot of production frames done with Redshift using the Houdini ocean tools. You can search on the Redshift forums for some success stories.

Ok, cool, thanks for your time, and the info, heading to the RS forum!

Not sure if this might help, but basically they're pulling displacement from the terrain maps right into Redshift. So perhaps the same idea could be applied to the ocean generator?

P.S.

I still wish these forums included a sub-forum for Houdini Redshift users in order to help with questions like these. The Redshift forums are not really set up for topics such as these, and are mostly used to report bugs.

The Redshift forum is the BEST place to get workflow help - they are monitored by Redshift support staff and very helpful users like myself.

I must say that the Redshift forum needs more subcategories, cant find much on it, but I think that I have a sense of how it works!

Okay, this video gives pretty much all the needed information to export Houdini ocean to external render engines, even shows how to composite the whole thing!
