Title: Material behaviour changes without any apparent reason
Post by: TeoRossi93 on 2020-12-18, 23:08:43
Hello guys,

I was going to render an animation I'm working on but after few frames I noticed that something was wrong. The behaviour of the plastic and liquid material (image attached) are completely different from my tests!!!
I can't understand what happened, I just added render passes and tweaked some animation curves before rendering the whole thing.
I'm using a volume scattering for both plastic and liquid.
On the left is the image as it should be, on the right is how it renders at the moment.

Ok guys I solved the problem. The multipass tag applied to a material modify it's aspect, I don't know if I'm missing something or if it's just a bug.

Are you saying a Corona Compositing tag? I've never heard of a Multipass Tag.

Since compositing tag is used to create multipass masks I did a mistake when writing the topic. Of course is the compositing tag.

Just wanted to make sure. So what settings did you use on the Compositing Tag? Are you separating several element onto their own layer? Are you exporting a AE comp or are you manually stacking your layers?
