OK, I have finished to modify SRTtoASS3D.tcl v0.5. It will be distributed with the next release of BD3D2MK3D. In the meantime, can you (or anybody) test it carefully ? It should now convert the color tags correctly, even when they are specified together with a font change. The font change itself is disregarded, for the reasons explained above.
The reset to the default color has been simplified too, and is now {/c}.
Please note that this is a beta, so please copy the original SRT2ASS3D.tcl file from the toolset folder elsewhere before overwriting it with this version, just in case...
