Thanks goafreak.
I also did some experimenting with the options using the “Save Frame…” option via the RMB menu in RenderView … and a contributing factor appears to be the ZIP compression of exr files.
I tried switching to no compression and got a crisp image, however an HD resolution frame went from 450KB to 32MB in size.

When I render interactively in the RenderView using a ROP, the texture detail in my image is tack sharp.
When I “Render to Disk” to disk via the button on the same ROP, the resulting exr image is a noticeably blurry.
When I save the interactive image out from RenderView to exr, it is sharper than the “Render to Disk” method, but still not as 100% sharp as the image I see in the Render View.
I've tried viewing the image in mplay and Nuke and am getting the same results.
Are there some settings I can adjust on the ROP to increase the quality of the exr's being output?

That is so impressive .. thank you Enviob!
I'll take a look to see what I can learn from it, however it's a slightly different effect than what I'm going for.
Here's a cube example online:

I did find this demo which is close to the idea, where instead of growing the poly's, the object is folded/assembled.

If there is a more elegant or controllable solution that let's one go from totally flat to assembled, I'm very interested.

I want to take an icosahedron (a 20 sided object) and animate it to fold/unfold from a flat surface as if it were like Origami and being folded to make the shape.
Does anyone have any suggestions or might there be an existing solution on how to achieve this?
Thanks,
Frez

Technical Discussion » Using Houdini/mantra as a Lighting tool
- frez

Hi there,
Our studio has been experimenting with Houdini/mantra as a shading and lighting tool on a project for a couple of months and we have tried various methods and tools in the standard offering.
There are some great wins (like shops, vex, mantra's PB renderer, Houdini's viewport and speed) however we've hit quite a number of challenges and have questions with regards to lighting workflow and scene management.
Is there anyone out there using Houdini/mantra as their main lighting tool for film?
Here are some initial questions:
1. How do you group and manage your lights (ie: bundles, categories, something custom)? Also why that choice over the others?
2. What is your method for maintaining light links (light linking pane, data tree, material style sheets, something else)? Also why that choice over the others?
3. If you're setting up an initial broad sequence level lighting setup, how do you push that setup across a large number of shots?
4. How do you manage and override those sequence level settings (light params, materials params and anything else) at the shot level without affecting the inherited sequence setup? Is there a way to inspect the settings you've overridden or revert back to the inherited sequence level settings?
Any other general advice or recommendation is greatly appreciated.
