Latest Sasquatch version is 1.8

New Features

  • Windows 64 bit native version.
  • Significant speed increases.
  • Updated multithreading core, now supporting more than 2 cpus.

Known LightWave Issues

  • LW reports incorrect fog color values to plugins when transparency is used, sometimes causing incorrect fog colors to mix with fiber colors when seen through multiple layers of transparency.
  • A LW 9 bug can cause Sasquatch rendering errors if the Display Subpatch Level and the Render Subpatch Level(per object) are not the same and Subdivision Order is not set to First. Workaround is to make Display and Render Subpatch Levels equal.

Known Limitations

  • Mac only: Sasquatch's renderer is still single threaded.

Sasquatch version 1.71

Bug Fixes

  • Bias -Y Combing rotation values were incorrect. Fixed.
  • Tip Translucency value overwrites Translucency in save files. Fixed.
  • Shadow of Sasquatch panel has a (large) invisible "About" region on top, makes it hard to press top two "A" buttons. Fixed.

Sasquatch version 1.7

New Features

  • Effector Combing This lets you use one or more effectors to stroke the fur combing in a limited region without affecting the combing anywhere else. This can help to fix up small areas, like angling tufts of fibers out of eyes or tuning the flow of fur around a mouth. It uses effectors much like Acid. The effectors can be moved, rotated, and stretched to define the combed region. The combing is in the effector's -Y direction. You can use as many effectors as you like. There's two independent channels of effector combs so you can texture map the strength of groups independently.You can also change the strength of indivdual effectors by using that effector's Polygon Size. Effector combing is added to the previous "smart" combing and bias controllers. Probably you'll set up most combing using the older methods, and add limited region effectors just to fix up the small areas that have remaining problems.
  • A small speed boost, about 5%.
  • A new generic plugin, "Sasquatch Panel", which is like the G2 and FPrime generics. It's a convenience tool to bring up the Sasquatch pixel panel without having to dig into the layers of LightWave panels to get to it. You'll need to use "Add Plugin" in LightWave.
  • Support for 64 bit dongle drivers.
  • Wider image picker to show longer image names.
  • Panels are all now nonmodal, a significant workflow boost.

Bug Fixes

  • Minisliders on the Mac won't crash anymore. (!)

Sasquatch version 1.6

New Features

  • Multithreaded rendering is much faster for scenes which use Fur mode on complex objects. [The "Receive LightWave Shadows" option is still a huge bottleneck unfortunately, but with that option off, rendering flies on dual CPU machines.]
  • Item and light picker buttons now give more informative summary labels.
  • The Mac version now uses a progress meter to display Sasquatch rendering status, and also allows aborting the render.
  • Load-from-scene support is now much more robust, and handles even cloned objects.
  • LightWave's Z buffer is limited in depth resolution, a natural limitation. This can make extremely tiny hairs (like velvet) disappear or flicker when the object is very far from the camera. A new control, "Z Buffer Precision Bias", allows you to force fur intoview. This needed for very very very few Sasquatch scenes.. but is now available for the (er, one, poor animator!) who had exactly this bad luck. Ignorable for just about everyone.
  • The render status bar now prints the segments that are being rendered.
  • Minisliders on Macintosh now work like the PC, keeping the cursor "unmoved" after sliding, and giving no limits to sliding distance. [A very annoying limitation in older versions!]
  • Objects that used bones with expressions and many many child bones were very slow to render in Sasquatch. This is from the surprisingly slow speed of LW expressions, multiplied by the number of times Sasquatch needs to query those bones to compute dynamics. This was particularly common on objects set up with the ACS4 tool. We've eliminated the bone query for the common case where no dynamics are computed. To avoid the slowdown for scenes with fur dynamics, you may want to pre-bake the bone motion of those bones with expressions (or just remove the expressions) in order to speed up those scenes.

Bug Fixes

  • When using Sasquatch transparency mode, sometimes a stray pixel appeared at the edges of silouettes. This was a floating point precision problem. Now fixed!
  • Using backdrop image fog would cause funny colors in Sasquatch fibers. Our bug, a remnant of LW 5.6 support. Now fixed.
  • Combing nulls wouldn't comb right if they were parented in a nested heirarchy. Our bug, from a Bad Assumption. Fixed!
  • Sasquatch image maps were mis-scaled by 0.02% as compared to LightWave's maps. This tiny mismatch was nonetheless noticed by a very alert Steve Hoefer. Fixed!
  • When the camera was very far away and zoomed in close, shadows could be offset from their "true" position. The renderer now mostly compensates and the offset is much less severe. Reported by Bob Landry.
  • Onepass antialiasing could show a "ghost" of colors behind an object
    if there was a very sparse layer of fur on a front surface. This was from the one-pass algorithm saving memory by storing less color information. The algorithm has now been changed to behave more accurately in most cases, eliminating the ghosting.
  • Sasquatch may have made invisible (black) objects in scenes using ultra-negative lights visible. Fixed.

Isolated LightWave Bug

  • PC Sasquatch can now always reliably read scenes saved from Mac
    Sasquatch. This is from a LightWave bug that has been documented and reported to Newtek. We also applied a workaround to Sasquatch itself.
  • A LightWave bug would (very rarely) corrupt Sasquatch's UV maps when applied to multiple objects. We isolated and worked around the problem so maps are more reliable.
  • Diagnosed a very slippery LightWave bug when using discontinous UV maps for texturing Sasquatch parameters. Sent an analysis and example to Newtek for fixing. Thanks to Chris Dardis for his test scene!
  • Diagnosed an occasional problem with flickering shadows when using shadow maps, especially with high fuzziness. We isolated and documented the LightWave bug and submitted it to Newtek. [Thanks to Wet Cement and also Dave Tracey for test scenes!]
