On it again.Gotcha!



Just playing with layers now I have a scene where characters are not stood on ground planes (you really do need to fix that one!).

When rendering out layers the background you are going to key out for your composite layers is very important. Could we have a drop down instead of the tick box for the background layer. The choices would be original/black/green/blue/red and then it would change the background appropriately (don't forget we want illuminated and no shadows on the background if poss).

What do you think ?

Would you not set that up using the environment favourites? That's where the list of original/black/green comes from isn't it? All the options you mention (illuminated and no shadows) are configurable for the sky and ground anyway.

If you are using render layers, you shouldn't really need to key anything out. A character rendered on layer 1 will have a transparent background and a arcade machine he is playing rendered on layer 2 will have a transparent background. So you can basically ignore the "background" layer and just composite layer 1 & 2 with another photo (of a arcade venue) without keying anything.

Or am I missing something?

Posts: 975 		I will have another go, but when I rendered out just my character layer the background was black so I had to key it out. That's why I suggested an easy way to change the background colour to make keying easier.

Transparent would be great, but that's not what I got. I used AVI uncompressed and HitFilm.

I'll have another play and use a couple of compositors tonight and see if it really is transparent.

Would I be right in thinking you'll only get transparent with TGA output, rather than video?

If that's true then I think we might need those chroma key options in the render menu.

Posts: 2220 		I rendered this scene a couple of weeks ago in DX9; Now I'm rendering it with DX11 and it seems to have a much longer predicted time. Is there a significant difference in render times between the two or am I doing something wrong?

It's about 3 minutes of 1080p.

Edit: I've since aborted the render and realized that it's rendering the layers individually. Could we have an option to render as one layer without switching to DX9?
Update: Rendering in DX9 is much faster:

Ah-ha! ok, I hadn't realised you would be using layers and AVI. You will only get transparency with TGA sequence files.

My 2p is that there is more setup needed to achieve a green screen background than can fit on the output window, and also the background layer is the sky and ground (+anything else left on the background layer) so additional changes would need to be made to select what layer the sky and ground (if they are separate choice for the sky and another choice of layer for the background that could get confusing) are on as well as being able to duplicate the edit environment settings on the make video window.

I think TGA would give you the best quality output and avoid any artefacts around the edge of the key'd character/object. To get the best, quickest result I'd go for TGA sequences - and you'll avoid the 2GB file limit on AVIs as well.

I have been meaning to move to TGA for a while so this will push me into it. I can confirm that it all works as described with TGA - brilliant. Forget all the greenscreen request stuff - no need.

Two things though....

When I render layer 1 I also get a folder called "layer 0" with a load of TGA files that seem to be all black in there. Is there any need for this ? My "layer 1" folder is correct.
What does the "depth pass" check box do ?

Thanks

Berty

Layer 0 is actually the background layer, this should be renamed on the output...
Why is it black? My own tests just gave me a white/grey default sky/ground. If you send me your set file I'll take a look...unless you purposefully set the sky and the ground to black? Big Grin

A depth pass lets you do some fancy stuff in comp/post process. I'm not all that familiar with HitFilm but in AfterEffects you can use it as the input data to effects. So, for example, you want to add Depth of Field effects later on this depth pass lets the effect know the depth of the scene to apply the effect. That's probably the most common use, but really its just data to tell another application how far away things are so you can use it as an input into other effects.

It is black because my background was set to "no image". I have reset this to a background image and it's all as you say (of course).

I now see... Basically if you're using layers then forget AVI for multiple reasons. Just thinking how we stop the forum filling with numpties like me trying to use AVI and layers - could you put something on the render layers dialog saying "For better results with layers use TGA sequences" if they have selected AVI ?

You should be able to use the Render flag on the Show Layers window to dictate what layers are rendered. This way you can get one out at a time.

I have to ask though, if you've spent the time configuring what layers everything is on why would you then want to just render it as a flat video? Possibly as a preview render?

I'm sure this is possible.

As far I can see layers have two uses :-

  • To give the the ability to render out individual layers for use with composting
  • Hiding things in complex scenes so your PC becomes more usable


If your using them for the second reason then you may want to just render everything ??

Fair point. I've never really considered them as an optimisation though, I kinda of see that as an excuse to cram more and more into a scene rather than try to properly optimise a scene.

I've been using them to optimize my scenes - I cram a lot of stuff in anyway
I also keep pumping out test renders because I can't get Muvizu to play back the scene as it would appear without lagging.

Posts: 151 		I put in a request with the dev team for a 'flat render' or 'preview render' (whatever you want to call it) option. I can really see the benefit of that for previews of your work.

If you use render layers to optimise your scene, I wouldn't be surprised if your scene suddenly crashes when you turn a random combination of really full layers (or all layers on at once). Just saying...

hehe this thought just came to mind and its not like you guys dont have a lot of work to do already but have you ever considered holding livestreamed workshops for muvizu users on stuff like say scene creation or storyboarding and stuff. You can use twitch or some such provider or google hangouts (although not a fan of the google ones) and since you put muvizu on steam twitch sounds like an appropriate venu.

anyhow back to the bugs i was just reading stuff while heating up the veggies for diner.
