Strange shaders behaviour of tp.slide.jxs / cc.scalebias.jxs between max 5 & 6
Good evening maxers,
I'm having trouble with tp.slide.jxs and cc.scalebias.jxs shaders combination.
I used it four years ago in a patch in order to draw with slow fade down. I used max 5 and it worked perfectly even if I used a veeeeeeery long fade down time...
Since then, I moved to max 6 and tried to reopen it few month ago, the fade out wasn't working properly:
Over a certain amount of time (slide_down parameter = 114), the drawing won't totally disappear.
I joined a test patch to that post, that would help you to understand and test between max 5 and 6...
Any help would be really appreciated, this is used in a 365 days/year running patch and I need to modify it...
Building an app on max 6 would be very nice due to the nice new features!!
Benoit.
Hi,
I looked at it but I don't understand why it's not working either.
How about using the standard jit.slide object ?
Hi,
Thanks for the feedback. I already tested jit.slide object but the slide down parameter has a too short effect.
Here's two samples of use with the shaders:
Almost infinite time:

Is someone from cycling has any idea of my solution?
Thanks again nimar.

Hi all,
I'm still bothered with this Max5/Max6 shaders topic. Can someone can have a look at it?
It would be VERRRRRY helpful.
Thanks a lot.

Hi all and Hi Benoit
i have the same thing and you know why Benoit
Nobody have a solution for that?
Thx for your response, you help us
Best regards

AFAIK, this is a common issue with graphics apps, and is very display and GPU dependent.
one way i've overcome this in the past, is increasing the gamma attribute of jit.displays.
for what it's worth, on my particular machine your patch works as expected, and the trails disappear even when i increase the slide parameter.
Thanks a lot Rob.
Can you please tell us the specs of your machine (at least your graphic cards)?
Benoit.
@Simon : I don't get how your first patch could work as the flonum box isn't linked to the slab sliding object... After adding an attrui, it works ok for me.
Edit @Simoon. Ooops sorry ! Going to have a look at it in the GL world...
@Stephane : You opened the NIMAR's patch, not mine.
As I explained in my answer to NIMAR is that jit.slide has a too short trails.
If you have a better solution (in the GL world), I would love to test it.
Thanks.
Benoit.
@ Rob: Also, What I can't understand is: why is it working on Max5 and not on Max6 on the same computer (same graphic card of course)
B.
@Simon : for me it works until I go beyond 150. with the flonum. Do you have the same result ?
@Stephane :110 for me
And btw works perfectly in max 5.19.
The tp.slide.jxs example works fine for me in max6, is that the case for you ? (jitter-examples > render > slab-helpers > temporal)
