Color modes bug

[Vincent-Ravel]

Hi,

I've just found a strange bug on color modes. I have few red solids in multiply mode and they doesn't react to each other, they just react with the background image.

Someone can help me ?

After Effects is working properly.  When applying a blend mode to a layer, the layer will affect the the layers BELOW it.

The layer will NOT interact with every other layer in the composition.

Change the color of a layer and you will see that they interact to each other if they have different colors but not when they have the same color. This is not logical, in multiply mode they would interact even if they have the same color (in my opinion).

If you change the layer order, you will see how it affects the look.

It's working fine for me. Could you share your project file so we could take a look at it?

Thanks for interesting to this problem Szalam. I think it's a bug on apple computers... I've done the same thing as you but still have the problem.

Here is my project file

I normally frequent the Photoshop forum not after effects but I may have some insight.

Are these blocks full red (in RGB terms 255,0,0)? If so , multiply will do nothing between them. The output of 255,0,0 multiplied with 255,0,0 will still be 255,0,0.

Multiplying with the darker background layer will of course have an effect (as you are seeing).

You are right Dave, my blocks are full red that's why they doesn't blend. I had a misunderstood of how the multiply blend mode works ! Thanks for your lighting
