Model Deform Node Ignoring Comp Effects (1.5)
I’ve found a bug where the Deform Node ignores precomp effects.
I have a primitive plane model with a deform attached, in 1.4xx i was able to affect the deform with a precomp using multiple effects – mostly using the ‘extract’ effect – to remove areas of fractal noise using luma values.
In 1.5 it seems the deform doesn’t render these changes. I have tried different colour depths, different settings inside the deform (source, masks etc) and i am unable to achieve the desired result.

The deform ignores the extracted comp and only uses the fractal noise comp, they are 2 separate comps that have been pre-composed into a single comp.
Could you please send us an email with a sample setup / more details so we can look into this ?
Yeah sure, sample setup is here: https://drive.google.com/open?id=1_FH3Oyiesds2d4uiNdYQ5PRPNURo1KyK
It’ll ignore the effects applied in the first precomp (extract effect).
Hi Nick , the way AE works is that it save the color info in un-premultiply alpha , meaning, that when you apply extract, the RGB channels are not affected (you can set the Show channel to RGB straight to see the actual RGB) , the Deform / Maps , reads the lightness of the RGB, so please have a black solid under that extracted layer in the pre-comp, this should give you a correct RGB map to distort.
