Hi Remy,
I havn't seen this problem before.
Are you using BASIC or FRAGPROG emulation? (FRAGPROG
emulation requires support for ARB_fragment_program).
The output from your performer app should help you determine
which method you are using (set PFNFYLEVEL to 7).
Which graphics card are you using? Which driver version?
A couple of things you can try are:
1. try setting the environment variables listed below
(try setting each one, and both, to the value '1'):
_PF_CLIPTEX_APPLY_SUBLOAD_BUG_WAR
PF_FLUSH_EACH_CLIPTEXTURE_SUBLOAD
These are there to workaround driver problems on ATI hw
so may or may not affect your problem.
2. Try viewing your .ct file using clipfly. Bring up the GUI panel
and 'select' your cliptexture (there's a widget labeled 'ClipTex:'),
then press the 'o' key (for overlay) and you should be able to see
the contents of your emulated cliptexture displayed in overlay.
Are the overlay images also corrupted?
Regards,
Paolo
