Dull colours
on Aug 1, 2011 at 4:21:30 pm

I have imported a .aec file from C4D and performed a multipass render. I am trying to get the reds to 'pop' and become more vibrant because after exporting the project from C4D the reds seem terrible. I have also changed the Linear workflow settings so that AE is set to 16 bits per channel, sRGB and Linearize the work space. I have the words that I want on separate layers ready to change their colour but not 100% where to start.
The colour space in AE comes across as quite dull and matted the colours in the colour palette all seem dull even after selecting the most saturated sections of the spectrum.

What the best point of action when making colours more vibrant. I've started with hue/saturation plugin and used a curves plugin but not really getting anywhere.

Any help would be greatly appreciated.

Thnaks

After going through some of the individual files/layers of the multi pass I can see that the 'diffuse layer' & the 'matt colour layer' have the original rgb values and look how I want the colour to look. Its only when the whole accumulation of the layers happens that the colour becomes washed out. The only think that I can think of is that it is something to do with the reflective surface that I have put on in C4D???

Don't really understand what is going on.

That makes sense.

On the C4D side, what is in the scene for the surfaces to reflect? If they are just evenly reflecting big lights or a big bright sky, your objects can easily wash out. Using a Fresnel shader in the reflection channel will make the amount of reflection dependent on the viewing and lighting angles. Using an environment channel instead of a reflection channel can let you cheat and get nice image-based reflections.

Back in AE, the beauty of doing multipass renders is that you have total control over how all those passes are composited. You can lower the opacity of the reflection pass to decrease its effect on your scene, or even manipulate the reflection pass with other effects.

Hi

That has definitely I didn't know that about the Reflection & Environment, thanks!

Now I'm having trouble exporting the file from AE because even though I have selected Alpha in the C4D render settings AE is not rendering out the file with an Alpha channel....what could that be?

Much appreciated!

I'm a bit unclear on what you're asking -- are you not seeing the alpha channel from your C4D render in AE, or you can see it but are unable to render with alpha from AE?

Hi

When I do a basic render from C4D no multipass just the one file then take the .aec file into AE and open it I can select the 'Toggle transparency grid' and see the transparent BG (the alpha)

However if I perform a multipass render and select all the relevant layers that make up the scene and save that .aec file and open it in AE then open that comp there is no transparency (when I use the toggle transparency grid function) Craig alluded to the fact that the combination of the layers are additive http://forums.creativecow.net/thread/19/875152 so therefore I can't see the transparency. I don't understand the concept of matting it with the RGB channel like Craig suggested.

After a few renders I have successfully been able to render out a basic scene (top of this post) and use object buffers to change the colours of the text which was the main problem BUT I don't then have control over the other multipass sections.

Thanks for your patience in this I'm currently climbing a big learning curve which thankfully I'm enjoying!

Thanks
