Pegasus takes off!

Finally we are releasing Clarisse 3.0 codenamed Pegasus! You can already download the latest PLE and play with the updated contents. So what I can say is about this new version? Simply we’re all very proud of it! Yes, we’re very proud because we wrote a new path tracer from ground up. We’re also very proud because we have improved greatly look development in Clarisse through the new Material Editor, OSL support and advanced baking tools. We also revamped completely the manipulators including the implementation of snapping and alembic export to simplify layout. Scripting is now made simple thanks to python command output in Clarisse log. Just check out what’s new since 2.0 and remember this release note doesn’t include bug fixes!

A bit of background on this release

We started working on Pegasus core about 23 months ago. At the time we were just 9 at Isotropix and we end up releasing it with a team of over 30 people! We just tripled the company size and we keep growing!

3.0 is the result of hard work and close relationships with people from major studios such as DNeg, ILM and WETA but also smaller sized ones. The core of 3.0 is a tech that helped creating the VFX of many blockbusters including Star Wars The Force awakens, the upcoming Star Trek beyond and many more. Here is the up to date list:

Finally I invite you to come and visit us at SIGGRAPH 2016 booth #367 to see live demo of Clarisse 3.0! Hoping to see you there!


Clarisse 3.0 improved fur interpolate object

Clarisse 3.0 improves its fur interpolate object. It now allows to grow fur along guides using two growth behaviors that can be blended.

The fur interpolate object of Clarisse 2.0, didn’t provide any other choice than using full guide length to interpolate furs.

Now we can control fur length within Clarisse, which means that different alembic files are not needed anymore to get different fur length variations.

Fur length can of course be controlled by any map type, file or procedural. It can also be animated, therefore we can now grow fur based on one single GeometryAbcFur within Clarisse.

New texture driven Point Cloud generation!

Clarisse 3.0 (Pegasus) introduces a new point_uv_sampler  geometry that samples the UV values of the geometry support in UV space which makes it much faster and way more efficient than the point_cloud that does this evaluation in 3D space.

point_uv_sampler is not meant to replace the point_cloud.
As already mentioned the point_uv_sampler samples the UV colors of its geometry support in 2D space and as a consequence it can’t take any other scene object than a single mesh as geometry support unlike the point_cloud that can use a combiner.

This is the flip side of the 2D space evaluation but its advantage is that the point_uv_sampler will be much faster in evaluating its density according to UV colors.

Unless you really need to use combiner or any other scene object than a single mesh as a geometry support, the point_uv_sampler brings a significant gain of performance.
