Try and solve this one! Edge of a layer is missing!
ok, so ive got a load of 3d layers, all at various angles etc, but one of them, a cloud, for some reason is cut off about a quarter of the way to the edge. i just cannot work out why.
ive checked it in photoshop and its fine, the rest of the cloud is there, ive tried moving it in after effects, reloading the footage, bringing it forward incase it was behind something, pushing it back, all sorts.
the edge just isnt where it should be.
there are no masks on it, or any special effects. it just stops, right before where it should. and im not saying that the image ends, and the layer carries on, its the layer that stops. like theres not enough room in the layer for the image?
it also seems to only do it on high quality and when i render it out.
any ideas?Ben Weller

ok, so i thought maybe it was another layer affecting it, so i was going through them all switching them all on and off one by one, and i think i found it. i have about 360 layers in this composition, about 100 of which are tufts of grass. as i switched off all of the layers of grass, the cloud layer went back to normal. but when i switched them all back on again it cut the end off again.
i tried going through each piece of grass one by one, but it seems to just be random grass layers, each contributing to cutting a small piece off the layer.Why is it doing this?
The grass layers and this cloud layer are not in contact, theyre not partnered or even connected in any other way. ive even deleted the cloud layer and put it in again fresh, and it still does it. im very reluctant to delete all of the grass layers, because, as i said before, theres hundreds of them and it would take too long to put them all back.
if anyone can tell me whats going on it would be very much appreciated, this is driving me crazy, i was supposed to have it rendered out by lunchtime and im still trying to fix it now!!!

Can you pre-comp some of the layers together as you go . . . to eliminate some of the complexity? I’ve run into unexplainable issues in the past, solved by pre-comping, or eliminating effects not meant for 3D layers.

Hey ben, that sounds frustrating.
I would try moving the clouds back in z space first.
Are the grass layers much larger than the visible grass that’s on them.
Maybe crop them down as small as you can?
Are they pre-comped.?? Can you pre render them??
It could be a bug caused by soo many 3D layers.
(and always toggle the collapse transformations switches as part of any trouble shooting session.)Thats all I can think of.good luck

well i would precomp them, but the layers are that big, it wouldnt work so well. the grass layers are all cropped down as small as they can be, and ive tried moving the cloud layers back in z space already. interestingly, one thing i did come across is that if it passes a certain point in z space, and simultaneously in x space, thats when the edge disappears. if its one the other side of those points, its fine. unfortunatly the side that its fine on, is nowhere near where i need the cloud to be!
so i just stuck another cloud over the missing bit. lol.
whats this pre-rendering you mention? will it help deal with the sheer number of layers? (there wont be this many layers in the actual working versions, ill delete the stuff out of shot and what have you, this is just the way i work)Cheers guys.

[Ben Weller] “whats this pre-rendering you mention?”
pre-rendering is a way to decrease render times and processing demands for a comp… to effectively pre-render, you’ll need portions of the comp that are pre-comps. then can you just open a pre-comp and choose composition>pre-render. this will place the comp in the render queue, but with an extra post-render option set to import and replace usage. which means after the pre-render is done, it will import the clip and place it into any comp that is using the pre-comp that was just rendered.
you’ll still have the original pre-comp(s) in the project if you need to make changes later, but you’ll need to re-render the pre-comp or replace the pre-render footage with the pre-comp in any comp’s that used it…
it’s really useful, but i’m not sure it would have helped you here…

Try to precompose with camera inside the precomp and keep the layer in 2d, or a better idea, render only the grass in alpha and then composite with the cloud.You said “Interestingly, one thing i did come across is that if it passes a certain point in z space, and simultaneously in x space, thats when the edge disappears. if its one the other side of those points, its fine”,so just move/adjust your anchor point to adjust the z and x to the position you said is clean, with the cloud positioned where you want it to be.
