#PAR No Alpha Prob
6 messages in this thread
I tried what you suggested but I'm still having problems maybe you can tell me
what I'm missing. First thanks for the info about the wildcard select in the
par software, I had missed that before.
The first thing I had problems with is that I couldn't bring in the 8-bit alpha
split .TGA's into PAR ( Do I need to lower the buffer size?)( I know I have to
raise the buffer size to bring in 32 bit TGAs) I noticed someone else on the
board having the same problem. The other more important problem is how to get
the alpha channel file to act has a matte for the 24-bit file in Razor. I know
how to do it in 3DStudio. I know that Razor has a enable alpha channel checkoff
in the media pull down but it doesn't turn active unless there is a alpha
channel present. I still havn't figured it out. Any help would be appreciated.

The PAR will only deal with 24 or 32 bit Targa files, just call up the 8-bit
alphas as a 3DS background and render directly to the PAR if you need to!

G nailed it – the best way is to rerender the stream as background – i've
tried to use batch conversion programs but 3DS Videopost is so much more
intuitive – sorry about the missing step – been a few weeks since i worked
throught the same scenario – remember the final is simply a grey scal moving
matte – you have to use the RP matte function not the media alpha channel
selection… "locked" i just ment ensure both ani's were aligned in the
composition window

The only problem with that is then IFL's won't work. But I learned how to get a
good alpha split from 24 bit tga's and that is done by putting the seq.tga's in
the queue and put the same seq. tga's in the queue alpha
channel in the rgb mask queue with intensity option active. Then render with
alpha ON optionally with alpha split ON. Does that make sence?

Sure they will! IFL's always work!

No, but if it works for you, it's fine by me! :^)

Your right it doesn't. I spoke to soon. But I did eventually get it right. I
was trying to get a good alpha channel (not all white) from tga's off the PAR
(24 bit). If I rendered the tga's through VP and turned alpha on in the render
dialog the alpha channel would be all white. But if I rendered the tga's
through vp with alpha queue active and alpha on in the render dialog there
would be a good grey scale alpha channel. I had to check it out in Photoshop to
be sure becouse if I did a alpha split on the same 32 bit file the alpha
channel would be white again which is beyond me but check it out this really
does work and it's so fundamental. -=Mike=-
Ps I just did a some composites in razor to be triple sure and it works.
