After transforming in perspective, there is a weird parallax in the layers. How to fix it?

Post by Christilia »

Hello! I am very new to Moho so I am currently learning a lot but also trying to understand and find a good workflow. I made an asset in top view and then transformed with transform layer tool, shear and perspective to make it look less flat and position it. It has several layers so I put it in a group. But now every time I try to move around the asset as a whole with the group, the layers have a parallax effect as if there is an offset. It looks like Moho takes into consideration the 3D space in which the asset is transformed. However I don't se any values in the Z axis. You can see images with the issue below. I could use some help on how to fix this, maybe reset something or bake the coordinates. If anyone can help that would be great. Thank you in advance ^^ Image Image Image

The images don't show up here.

As a general rule: each time I use Moho's layer tools to construct something in perspective for a scene with camera moves, I render the finished object and re-import. This way my precious construction will not be broken by any further camera movement.

Here's your images:

Looks like there is an offset in the bread face layers. If you want to share a link to the file, it would be easier to know what's going on.
Generally with this sort of 3D-ish construction, you'd want to assemble it all without any skew or 3D rotation, and then only 3D rotate the entire group layer.

Now I need some bread with cheese.

Thank youu for the replies! I see, in that case then I might just redo the face parts of the bread in their 3D view already. I really didn't know Moho also has this 3D aspect to it.
I don't know if it's gonna be useful (it's a very simple scene) but here is the moho file in case you want to take a look: https://drive.google.com/file/d/16dE8yc ... sp=sharing

Also very random but can I ask Synthsin75, how did you put the images on the post so they are visible?? I rarely post in forums so I don't know all the little tricks, but that would be quite helpful^^
Thank you so far^^

Yeah, it's just the 3D rotation on those two layers. If you do it with the points instead, like you did the rest, it will behave when you move the group.

Hi. Instead of rotating the layers in 3D, you could use Quad meshes instead.
This kind of mesh will allow you to animate perspective without actually moving the layers in 3D.
It is not perfect, but I quickly adapted your file here:

Victor, do the extra points from the corners serve a purpose?

Hi. Yes. Quad Meshes work in two ways:
When a Quad is fully independent (no points or other shapes connected to it), it calculates realistic perspective.
When the Quad is connected to other points or shapes, it works as a proportional distortion mesh.

Here you can see perspective vs distortion:

(the perspective can sometimes look a bit off on the canvas, but it will look good when you render it).

My God, this one from the extra point there is totally new to me. Thank you very much, Victor!

Ah, that sounds familiar. Thanks for the refresher, Victor!
