3D Studio Release 4c1
In mid-January 1995, Autodesk will commence shipping (in the Americas) a
slightly revised
update to 3D Studio called Release 4c1. Here is a list of changes as of R4c1
for your reference.
This is not a "feature upgrade" to 3D Studio, it is maintenance update to
correct certain bugs
found since initial product shipment. Autodesk will be supplying R4c1 to
Autodesk Multimedia
Dealers (in the Americas) at no charge for specific customers who are affected.
The update
includes new serialized disks and a reprinted New Features manual.
Changes in R4c1:
1. In 3DS.exe, the Load DXF command now correctly accepts AutoCAD Release 13
binary and
ASCII DXF files. 3DS.exe now correctly handles splines during Load DXF when
not enough path
steps are available. Note: There is a patch on Compuserve called DXFPCH.ZIP
which will
modify the *existing* R4 3DS.exe to successfully read ASCII DXF files from
AutoCAD R13.
2. Revised the internal version number for 3D Studio Release 4 c1 (used by
IPAS routines,
Adobe Illustrator file output and Targa output) to 4.01.
3. Backgrounds and animated BXPs now resize properly when invoked via IPAS.
4. Faster memory transfer code in 3DS.exe can speed up certain IPAS routines.
5. Fixed a bug in 3DS.exe found with deleting KF tracks from the 3D Editor
programmatically via
PXP's.
6. Various corrections to the New Features manual were made. Primary changes
were to correct
errors in the IK tutorials and a re-write of the Match Perspective tutorial.
7. In 3DS.exe, an IPAS call to MTL_SELF flag is now returned as TRUE if the
self-illumination
percentage of the material is nonzero.
8. Fixed an IPAS-related text editor problem in 3DS.exe which could cause an
editable field from
an AXP or IXP dialog to erroneously appear in the middle of the display.
9. Fixed a bug in IK.KXP where a Follow Object with Scale keys not equal to
(1.0,1.0,1.0) caused
problems when solving for orientation.
10. Instances, morphing and self-illuminated objects are now correctly handled
in the Fast
Preview module.
11. Fixed a bug in Fast Preview that could result in an un-rendered scan-line
in the display.
12. Fixed a bug in Fast Preview that could cause improper backface calculations
when one of
more vertices were located behind the camera.
13. Fast Preview now draws only edges that are visible for faster performance.
14. Fixed a bug in Fast Preview where it was possible to get a negative ambient
light value when
the ambient light had keys.
15. Slightly improved the speed for Fast Preview when running in either 16 or
24 bit mode.
Memory leak also fixed.
17. The Background color in Camera Control/Fast Preview now uses the specified
color
instead of finding nearest match.
18. Various modifications to INSTALL program to allow installation of c1 and to
make each
Custom Install option more useful.
