More about cycling: You can cycle the rotation for a handful of different asteroids, and then Duplicate or Reference them, and offset them in Sequencer. Then, with everything in the group, you can cycle their positions. This is a simple setup, but with planning and the right grouping, it's easy to add more variables to this setup.

Yeah, I don't think Moho Physics work in Z, only XY. To get Z motion, I make instances of the Physics group and animate them in Z. This is basically a 'traditional' multiplane setup. Alternatively, can render an extra large sequence, and stack a bunch of image sequence layers and move them in Z or push the camera through them. Vector is probably more efficient, but sometimes bitmap sequences are easier to work with, so use your judgment. Use the Cycle trick to send distant layers behind the camera. This can reduce the number of layers you need. If you change the position or orientation slightly for each Cycle pass, they can look like a completely new set of asteroids.

So many ways to do this. I usually handle this type of setup in a compositing program, but it can be done in Moho as well.

Oh, one more thing: if you're shading the asteroids (like I'm doing for Space Tommy,) do this in the parent group level. This ensures the shadow and light sides are on the same side for all layers as each asteroid rotates.

Note: Moho's preview for shading can look wrong when GPU caching is active. This happens because what's cached is a still image, not rotating animation. You can ignore this display artifact because Moho will position the light and shadows correctly during rendering. If the incorrect preview is distracting, disable GPU Caching. This hides the effect in the display, but it will still render correctly.

Sorry to keep asking questions. Im kinda of a noob when it comes to making stuff feel 3d. But when using cycle how do i make the asteroid not look like it suddenly disappears and suddenly reapears. I really do appreciate all the help 😀

Moho doesn't have a native way to control opacity by distance from the camera, so I just keyframe the opacity in Styles or in the Layer settings over time. By viewing the scene from a 3D angle, I can figure out when the dissolve keyframes should kick in.

This works for Particles, too, if you decide to go this route. Just set the opacity keys in Styles or the Layer settings. (I haven't tested this lately, but I'm pretty sure it works.)

If it makes it easier, you can set up Smart Bones to control the opacity for certain layers or groups. The keyframes for these Smart Bones can be Cycled.

Or, you can use Sequencer to time the fade out.

All of this should be methodically planned...otherwise, you might create a lot of unnecessary work correcting settings for individual items, which could get tedious. I would start with a simplified setup using a few circle shapes, to understand how the setup works and how to scale it up for more items in the most efficient way.

Thinking about this gave me an idea. I wondered if I placed a Bones layer on its side, and used target to track a bone moving in Z relative to camera, that could be used as a Smart Bone to fade out a layer or drawings by actual distance. Didn't work though...even though the bone moved in Z, the layer moved along Y. I had set the layer to Face camera, so it should have still moved with the bone in its fake Z direction, so maybe this is a bug? I don't have time right now to investigate further, but wanted to mention it in case someone wanted to pick this up. Let me know how it goes, anyone. :D

Just thought id put a update to this incase anyone is wondering or it helps anyone out. i bascially used particles in the end, and found a setting in the layer setting called 'face camera' and change it to-change image plane x and it worked wonderfully. i just used the rotate layer xy to get the desired angle . hope this helps anyone :)

Awesome! Glad you got it working!

Post the results whenever you can...I'm curious to see! :D
