Scaling object with linear gradient
by Janis Jansons on Feb 24, 2006 at 10:37:36 am

hi,

could anyone confirm that scaling an object with linear gradient on it, causes gradient 'strobe/jump'. Please make about 100-200 frames long animation as on fast movement it can be missed.

Thanks for reading,
Janis

If you are scaling the paint object itself, this might be an issue.

Is it possible for you to put the object on it's own layer and scale the layer?

this may help....

Thanks Alex,

yes that's exactly what I am doing and no, unfortunately I can not use layer scaling workaround. It would make complicated composite even more complicated.

Do you know by chance if there is bug reporting link like it was some years ago?

Thanks for your time,
Janis

perhaps you can make the gradient a higher bit depth?

hello Gary,

I was also hoping it would fix the problem but when I set it in footage properties to 16bit or whatever, nothing changes. It looks like gradient has scaling problems as the banding movement looks strange too.

Thank you for help,
Janis

isn't paint 8bit only, or have i missed something?
actually, i never really looked into that specificly.

workaround
by Janis Jansons on Feb 24, 2006 at 6:51:12 pm

Soooo... the workaround in my case was to use radial gradient and adjust it to match linear one.

Hopefully someone fixes linear gradient as all other types work well with scaling.

paint is whatever bit depth image comes into it.

[gary m davis] "paint is whatever bit depth image comes into it.

yeah, now you mentioned it makes somehow sense. using clone, for instance, wouldn't make any sense if it was downgraded to 8bit.

thanks for the info. next time i better think first and write than ;-)

cheers!
