I must say I am very relieved to not have to learn new software (Hitfilm) right now, although it's definitely on the agenda when my characters start shooting fireballs at each other.]]> Wed, 18 Nov 2015 03:03:44 GMT http://www.muvizu.com/Forum/topic5270-creating-drop-shadows.aspx Message from theotherguy
"Thank you for contacting Sony Creative Software.
After importing the image sequences, set the compositing mode of the shadow track to "Multiply (Mask)" rather than the default "Source Alpha". This should make it behave as expected. Depending on your workflow, you may also wish to make the shadow track a compositing child of the object track."

You know it's the first thing I'll do when I get home tomorrow! ]]> Wed, 18 Nov 2015 02:08:50 GMT http://www.muvizu.com/Forum/topic5270-creating-drop-shadows.aspx Message from mrmuviz The white shadow layer should be set to Multiply.

I hope this is what you are asking for. If the chroma keyer is not what you are looking for, try the channel blend and let me know if you get it figured!

Or, go with the HitFilm. I have it and it does work. I'm just much more used to my beloved Vegas.

1. When you import the sequence you'll get a properties window. Make sure the Alpha Channel is set to "Straight (unmatted)."

2. Right click on the video track header and choose "Set default track properties." Make sure "Composite mode" is checked.

That should do it--I assume your version works the same as 13, mine. It took me literally weeks before I figured this out!!

Of course you'll need to duplicate as many video tracks as you have layers, and arrange the layers in the proper order on those tracks.

When importing the layers in Hitfilm I have to set the blend mode to darken. This will darken the layers below it where there is grey or black on the image sequence. Any white areas will be unaffected. This means that white is effectively the same as transparent.

Not sure how you would do this in Sony Vegas.

I use Sony Vegas for all my editing, but Hitfilm for compositing. I like to have my shots rendered out before I put them in the editor as rendering them on the fly is slow and jumpy. I think you can do all the layering you need in the free version of HitFilm - https://hitfilm.com/express

If you download the free version and follow the instructions I posted earlier on this thread I'm sure you'll see what I'm talking about.

So I've set up my character on layer 1, with the shadow sharpness whacked up to 100%. Separate shadows are enabled on both layers.


I'm rendering both layers



oo-er, my pc is struggling with 1080p sharp shadows lol


4 folders have been rendered:


As Berty's said, the shadows are for what falls on the layer, so layer 1s shadows are like this:

And the background's shadows are like this:


I'm using Sony Vegas Movie Studio HD Platinum 11.
So we import the sequence as we would with any other image sequence. (selecting the first frame and ticking the image sequence box)


Repeat for all layers apart from the background colour.

Now I've come across a problem, my shadow layers have solid white which is especially odd since my colour layers have transparency. I'll key it out for now but I'll have to look into it.
I've set up the layers like this:


And this is the result:


You can see the problems with keying out the colour - Berty do you have any advice?

Conclusion: To get the drop shadow you need to only separate the background shadows, and I need to look into why my shadow layers are not rendering with transparency.



2nd attempt:
This time I tried with not separating the shadows on layer 1, and using a mask for the shadow layer:

The shadow is still too light.

I'll play around with it now, but I think "flatten layers" is not something that should be ticked for the shadows.]]> Sun, 15 Nov 2015 12:27:06 GMT http://www.muvizu.com/Forum/topic5270-creating-drop-shadows.aspx Message from theotherguy

Under the 'Layers' tab there are check boxes by the two layers, background and Layer 1

How should I proceed?]]> Sun, 15 Nov 2015 12:25:18 GMT http://www.muvizu.com/Forum/topic5270-creating-drop-shadows.aspx Message from MrDrWho13 Sat, 14 Nov 2015 23:18:23 GMT http://www.muvizu.com/Forum/topic5270-creating-drop-shadows.aspx Message from theotherguy
That's about it, I don't know how to generate the layered TGA files like you have shown so I can't look at the separate images to see if everything is correct. I have used TARGA sequences many times before and my video editor Vegas Pro handles them nicely. I'm kind of at a loss as what I'm to do now.]]> Sat, 14 Nov 2015 20:39:37 GMT http://www.muvizu.com/Forum/topic5270-creating-drop-shadows.aspx Message from ukBerty
You don't need greenscreen with layers - that's one of the beauties about it....

Just create a layer and put your characters on it.

If you select "separate shadows" when you edit the layer then you get two TARGA sequences when you render- one of the colour for that layer and one of the shadows that fall on that layer.

Therefore you will want to set layer 1(your characters) without separate shadows but your background with separate shadows.

Here's a set...



I have a single layer containing my character which is not set to separate shadows but my background is set to separate shadows

Here's what a layer1 TGA file looks like



Notice that this is a single layer and the character has shadows on him. These are the shadows falling on Layer 1 objects and you don't need these separated out, in fact it's simpler if they are not.

The background shadow layer looks like this...



Once you realise that the shadow layer contains the shadows that are cast on that layer and not by that layer it all falls into place.

Remember - you must use TARGA sequences for any of this to work - forget AVI.

In HitFilm I then assemble the layers thus....



You need to set the blend mode on your shadow layer to "darken". You can then adjust the opacity to change the shadow intensity.

So you end up with....



Obviously other compositors will have something equivalent.

It took me a while to get my head round it....

Hope this helps.....

I do all my animating against the included green-screen backdrop, I noticed that drop shadows do not work with it so I created a green ground plane. This seems to have solved the problem with shadows on the ground, or floor, but I'd like to cast shadows on walls etc. like in your intro. How would I do that?
thanks in advance]]> Sat, 14 Nov 2015 04:32:35 GMT
