Layer Dissect

Post by dkwroot »

Is it possible to create a 2d plane and then have that place dissect another plane in 3d space? For example, I create plane A and rotate it on the x-axis by 90 degrees so that it's flat on the horizontal plane. I then make plane B and leave it so that it's perfectly vertical. When I move the vertical plane (plane B) on the Z-axis, it doesn't actually dissect the horizontal plane (plane A), it just shows whichever plane has the highest layer order.

This is a big problem for me, because I'm playing with clouds at the moment. I created 4 long string on clouds with various z-axis values to give them depth. In order to bridge the length between these strings of clouds and created a cloud floor which is just a white rectangle which I rotated horizontally. I then moved this cloud floor on the y-axis so that it cuts the clouds in half, with the idea that this cloud foor would reveal only the bottom of the clouds when the camera is below the cloud floor and only the top of the clouds when the camera is above the cloud floor.

Well, this doesn't work ... The camera only seems to recognize objects based purely on layer order and doesn't recognize the fact that the cloud floor is dissecting the clouds, cutting them in half. Any ideas???

What do you need that white plane for? What's the desired result?

I created 4 strings of clouds. In order to do this, I created 4 long lines and used a brush with clouds to generate a stretch of clouds. So, I had 4 strings of clouds of the same size and everything. In order to create some depth for these clouds, I gave each string a different Z-axis value. This worked great and when I position the camera so that it's looking into the horizon, I get an awesome cloud effect ... Like an ocean of clouds (Which I actually gave movement to using the wave script).

Anyway, this works wonders except that when you pan the camera UP or Down, you can see the gaps between the clouds! In order to cover up these gaps, I created a large white plane which I wanted to dissect the clouds and give the illusion of the clouds all being clumped together with no gaps. Basically, the clouds should be cut in half by this white plane so that the bottom of the clouds can be seen when the camera is below the floor and the tops can be seen when it's above. This doesn't appear to work, because Anime Studio doesn't seem to understand the plane in 3d space very well and shows the entire clouds above the plane AND below the plane. You'd have to imagine how this looks when you pan the camera up ... The clouds don't interact with the floor and the entire thing looks fake and bad.
