Black BG PNG Images With VASST ScatterShot 3D
Hello and thanks for helping!
Following John’s ScatterShot Tutorial on YouTube…. I downloaded trial version of VASST ScatterShot 3D today. Seems awesome!
I am testing 3D Scatter of different colored t-shirts.
Pretty much using the default settings, I’ve imported 140 same-sized t-shirt images from Photoshop having saved them for web with black matte as PNG with transparnet BG.
Importing the png’s… -instead of them being transparent, each image has a black bg.
I rendered a sample movie -but the black bg blocks out the other layers. (I was thinking I could key out the black, later… but that thought was wrong).
Please offer some advice about using transparent png’s (Early on, I think I also tested psd files with same undesired result)
What is the best technique to perform my challenge?
Thank you,

Unfortunately png with alpha transparency show up as a black background until you tell Vegas about the transparency. You must select the properties for the png and select the type of alpha channel for each.
I don’t know if you can select a group of files in the project tab, but it’s worth a try.

scroll down to Alpha Channel,
Hit Ok. WAIT for computer…..
Select next thumbnail,

When I bring a png with a transparent area into SVP 10, Vegas properly displays the transparent area without any need to set properties. I know this because I can see the layer on the timeline which is underneath the png image. I’m not yet using SVP 11, but I think it will do exactly the same thing. Your problem may be occurring in Photoshop. When saving a one layer png image which contains a transparent area, the layer must not be named “background”. If it is, Photoshop will not preserve the transparent area. I am also careful that Photoshop does not save the png file as a copy. You can double check this by looking at the image after it is saved to confirm that transparency was preserved.

10-4 Chief.. Good Pointers..
Opening an old-PNG’s within PS-CS5 I see my 140 images are index color Mode (256).
Then, I’d created an NEW Action that changed the mode from index to RGB, Selected the transparent area, Did a Ctrl+Shift+I (invert selection)…
Created the Alpha Mask by clicking the icon below Layers Pallet (So there is now an Alpha Channel of -Black Area surrounding The T-Shirts themselves are the White Mask).. Saved for web as PNG-8 (not PNG-24 ~I forget why I choose that)..
Now, as a (random-hurried) TEST, I created an HTML WEBPAGE using (not Dreamweaver -but a MS Version called ~ahhhhhh.. FPage) (a really easy way to create a webpage using a GUI program that provides a simple interface to create an HTML Doc with Preview… -ah the backlash of FrontP haters…I hear you, echo-ing…)… I Placed my png Image on the page.. *In Preview Mode the image has a BLACK BACKGROUND, but when previewed in the BROWSER, its Transparent…
So I am uploading one image of my t-shirt, for the enjoyment of those interested in discovering whether or not I have create a proper Transparent Image using Photoshop with Alpha Channel.
Thank you, thank you..

Then I guess you will have to set properties in Vegas just as was previously described. For myself, I try to keep things simple by doing what will work in Vegas with a minimum of hassle.
