Right, so I see Set Matte is used to control the alpha channel and so the brighter the image, the fainter it appears.

So… leave the brightness in fractal noise alone, and in the Glitch comp, make sure the Group layer is selected, then go to Effect > Color Control > Brightness and Contrast.

There’s many different ways to make an image brighter, but brightness and constrast is the simplest. Here you can increase the brightness of the logo.

It’s a little hard to tell but I think there’s a clue in the displace label in the comp. I’m guessing that you’re using the fractal noise as a displacement map on the logo? In that case increasing the brightness of the fractal noise is increasing the white areas of displacement map which won’t make the logo brighter just make more of it displaced.

To get your logo brighter, you’ll need to add a colour correction effect to the logo

Here’s a link to a much older thread, but of a blast from the past: https://forums.creativecow.net/docs/forums/post.php?forumid=2&postid=198591&univpostid=198591&pview=t&archive=T

Expressions master Dan Ebberts came up with an option to mimic auto-orient for one axis.

Years ago I used Particle Playground’s wall settings to help explain Charles’ Law:

PP won’t get you particles interacting with each other, but will get the container interactions.

And does the code I suggested work for a non-parented solid? If you use additional nulls located at the positions where you want the solids, then use the code above on your solids’ position properties, then they will follow your null, respond correctly, but should be where you want them in 3D space.

It’s the technique I used for my Mars and moons tutorial.

Oh no. I hoped that would solve your problem. If you drill down in the project window to check out one of the VR pre-comps, you should be able to see what it’s passing through to the final render. The view will not be the same as your editing comp, but you should get an idea if it’s correct or not.

It might be that AE’s VR cannot cope with 4-comps or it might be something simple like you need to use collapse transformations. I get the impression that AE’s VR solution is still a really new tool – it was a script called SkyBox, purchased from Mettle. I had a pre-included version and it’s good, but felt a little “wobbly” at times. I can’t get it to handle 4K editing comps, for instance.

See if:


lookAt(fromPoint, atPoint)


in your shape’s orientation property can help.

Replace fromPoint with your shape’s position property and the AtPoint to be the null (I don’t think it matters which way round they are.

It’s a little hard to tell from your description, but it sounds like the coordinates are being set as relative to their parent, but Stardust (?) is based off these coordinates.

If you have a 3D Null object at 960, 540, 0 and you have a 3D solid also at 960, 540, 0. If you parent the 3D solid to the Null, its coordinates becomes 0,0,0.

You might need to use an expression like in the Stardust effect’s position property. This gets the coordinates of Null and bypasses parenting.


L=thisComp.layer("Null 1");
L.toWorld(L.anchorPoint);

When you make a change in Element 3D, are you switching between comps and rendering the output, or are you using the VR Comp Editor’s Open Output Render?

This button is more than a switching tool, it updates the subcomps to match the editing comp. If you drill down in the project panel, into the VR folders, you’ll see that what AE is actually doing is making 6 comps from your VR edit comp. each with a camera pointing in a different direction. It’s then stitching these together in the VR Output comp. So when you make a change, AE actually needs to copy your comp settings to the 6 other comps.

Apologies if you knew this already and this isn’t post isn’t a solution. It’s just a trap I’ve fallen into a few times.

Are you saying that when you change the Default Base, the next time you open After Effects it is back to being 30 fps?

And I’m not sure why you would want to change the project settings via a script. New compositions will remember the previous comp’s settings and in Edit preferences, the import options can be set to set image sequences to a specified frame rate. What is it you’re trying to acheive?
