1/95 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. [end]
