LCD screen Render layer
show user profile  silverday
Hi!

I've been asked to produce an animation of a concept mobile phone in 3Ds Max Design 2011. The animation will be about 1 minute long and will show the phone, particularly the LCD screen, demonstrating the main interface.

The phone's LCD screen interface (text messaging, contacts etc) will be animated together into an avi, which I am intending to map onto a plane underneath the phone's glass panel.

Here's the thing: there will be 5 different avi screen files in five languages - English, French, Japanese etc to demonstrate each language. Is there any way to save out the screen plane separate to the phone body so that I do not have to render out the whole scene for each language?

I've been experimenting with Render Elements but until now I've only used render elements for Zdepth and I'm not sure if this is the right approach.

Many thanks in advance

Which rendering engine? with max default's, f1 for matte material, I'd render:
a) the phone
b) the glass panel - if it only reflects the enviroment or the glass panels, if they somehow reflect the avi's-
c) the different screens

and comp them in post.

Cheers,

Manolo

Hi Manolo,

I'm using Mental Ray. Do you mean I should produce three separate renders in 3 files or is there some way to keep them in the same file, for example using a matte render element in an EXR or something?

Yes that's the way you should usually do it. In the end you'll have to put those 3
different layers -phone, screen, glass panel- and composite them in after effects or some other software. Haven't used .exr; I don't know if you're actually able to set different sets of objects to render on different layers of the same image. In fact, I'd find it a bit messier.

Cheers,

Manolo

Okay cool,

So how do I render different objects within my scene out to separate files?

For example, do I hide the objects within my scene and press the render button three times or is there a setting in the render dialog box?

Also, is there a preferred image format that you use for rendering? (sorry, bit of a tangent)

Depends, but most likely not as simple. If in the animation the phone, for example, turns around or whatever, then if you render the led screen only, with the rest of the phone hidden, it would appear backwards and visible for a while where it shouldn't (because it should be obstructed by the phone's body).

So:
a) hide the led screen and the glass panel. Render the phone's "body" animation. I usually do .png
b) rename the file just in case. unhide the led screen. Assign a "matte/shadow" material to the phone's body. Render. Repeat with each different languaje screen.
3) same with the glass panel. I don't think a matte mat. here for the led screen is necessary, just again for the body.

Note: when rendering with vray, you must within vray properties if an object is a matte one. I don't know if in mr you must state this also or the matte material is enough. Run a little test.

Cheers,

Manolo

That's worked really well!!

I've rendered the phone out in two parts - part1: the scene with the phone body and part 2: just the plane and glass screen with everything else in the scene having a white Matte/Shadow/Reflection material applied (the background is also set to white). I should be able to comp these together in after effects.

Thanks for all your help!
