With Pixie 2.2.6, and Pixie SVN.
I transcribe a detailed description of the error:
"This bug is actually with Pixie but I've added a "work around" solution
and updated the CVS Revision 1.63 ;-)
This is an issue I've known about with 64 bit build of Pixie for several
months now (my 32 bit Linux and Windows build seemed to work fine). I also
tested shader source against 3Delight, Air and Aqsis and concluded it is an
issue with Pixie that will eventually get fixed. Since it appears
development has stopped on Pixie I've decided to look into this again and
see if I can create a "work around" solution just for Pixie. The problem
appears to be in MOSAICSurface.sl line 181...
if (MatUF_X0[MAT_UF_ISTEXFACEALPHA] != 0 && Name != "")
There's nothing illegal about this line however it seems using AND with
the results of a float and string comparison crashes Pixie with a segfault
:-/ I have fixed this by comparing the float and string in separate
if (MatUF_X0[MAT_UF_ISTEXFACEALPHA] != 0)
if(Name != "")
This may cause a problem when enabling Blender's TexFace Alpha without an
assigned texture however this is not likely to be used so should be fine in
