Hm I suppose you're right.

Once I understand it in Max, then I'll branch out and do other things... this IS the reason they gave it to students free anyway... it's sitting on my computer so I might as well use it. Wasn't planning on selling the first test anyway... That'd be unwise to any extent.

MAX it is!... well at least for understanding 3D Space. ... and camea tracking... and stuff.

I've still got excuses and I have to work over those, but it's time to stop worrying about it and just do it... sooo here I go... I'm hoping my next post holds some results of trying to do this the right way without all the guesswork.

Ah thanks for clearing that up.

I've never importaed a character into Unity before so I never had the problem.

Only one issue (and it's going to sound like a lame excuse) remains...

While I DO have a student version of Max, if I ever want to sell anything I'd end up having to BUY max because I used it to export the character. I know it seems far off, but I am still thinking about it.

now I KNOW Max can't be the only program in which I can get an object exported with the proper local and world orientation.

For that reason, I'll use max to test and see if I can match those settings in Blender.

Wow and seeing as blender has totally different spacing, I'll have to match it to that as well.

Yep, I've got some testing to do it seems.... but for right now, I'll just be testing with iClone.

Thanks for the info.

Well I'll admit I didn't pay attention much to local space although I'm aware of what it is.

I'll have to do some more simple tests.

As for scripting local space in games... I cross that bridge when I get to it. I just want to make a simple 3D platformer game (kin to Mario or Crash Bandicoot.) So character animations are pretty simple. Hey I know it's not epic pro mode, but I gotta start somewhere.

Not saying I'm not going to learn it, but I'll figure it out when I get there... and to be honest I think I've already crossed this with parent and child animations in Unity in the past.

Also... visual node based scripting all day son!
(uScript and BrainBuilder are sick addons!)

In simple English as opposed to Sw00000plish
different 3D software suites orientate their x, y & z axis differently!
You just need to take this and scale into account.
Camera position is all you can bring over, other things like lens angle/type etc
ie wide angle, zoom, fisheye etc
cannot be easily copied.

Oh and also I still can't wait for 3DX for the basic reason of exporting animations from iClone.

Now I KNOW that bringing characters in through that means NO facial animations (yet) but I'm no character designer and I just want to get some things done and if I were to try to set up a standard character in max... it'd take me decades and I wouldn't get anywhere... well I might, but I'd rather spend thirty minutes bringing a nonstandard character in, popping some animations on, pulling that boy (or girl) into unity, and finish making the rest of the game...

So for that reason I'm still pretty amped for it. Also if all a user wants to do is get stuff in and out of iClone, they shouldn't have to drop 3+ grand and learn a whole new piece of software to do it.

It's kind of like you saying "Hey I'd like to burn a DVD." and me saying "well if you get Microsoft Visual Studio, you have the power to do ALL SORTS of things with DVDs and everything else! TOTAL CONTROL!!"... but do you really wanna learn to code just so you can burn your DVD?... No.

Dream,

Camera Tracking:
~ Start exporting everything in image sequences!
~ Export files as "RPF" or "RLA" Files!!!!!!!!!!

These rich pixel formats contain the necessary information, i.e. Camera Data!
Export These Images To.... HITFILM! or After Effects!

Easy way to transfer Camera Data, to say the least. They contain:
8-16-32 Bits per channel
store alpha channel
premultiplied alpha

Optional Channels:
ZDepth
Material ID
Object ID
UV Cordinates
Normal
Non-Clamped Color
Coverage

NOTE: This is the part RL left out of the importer/exporter!!!:crazy:
so use an external 3d app. to accomplish this!

As you learn more, you'll see why RL has used 3ds Max as it's Main Pipeline.
* It's 100 times easier bringing animation into iClone than trying to
repair iClone Animation!

HIGH-END animation can be "Imported" into iClone using object "Transforms"
and "SKIN WRAP"

Access to high-end 3d apps.... 3DXchange 5 is.... USELESS!

As everyone doesn't have 3 to 4 grand for Max... RL is going to make a Killing with 3dxchange 5!:D

Happy Camera Tracking!
sw00000p:cool:


Well as my camera automatically pushes everything into MP4s, there's no use in rendering a really high end image sequence. I usually put them in either PNGs or JPGs.

I already know they have to be images (which iClone also doesn't like importing for video) So I have the video like this already.

The video is already tracked, I'll export it as a 3DS Max file and import it there... then I'll export it as FBX or something after parenting and see if it works any better. Seeing as iClone works so well, I shouldn't have to worry about world spacing too much. (I'm guessing they share just about the same world space)... it'd be kinda silly to me if they didn't.

I'll give it another shot.

Thanks for your advice.

Dream,

Problem: Confusing "Special Camera" data and Understanding UV Coordinates!
Solution: Match the exporting UV Coordinates to iClone Coordinates!


UV coordinates?... do you mean world units? As I understand it, UVs have to do with texture space.

Finally: Understand that "All" of the animation is within the "FBX!"
The trick is understanding "ICLONE'S" LIMITATIONS!


I KNOW all the animations are in the FBX. This is the reason I parented the camera to actual geometry.

Please try and learn how RL wrote their importer and exporter!
That same fbx dropped into max... Would perform perfectly! [quote]

Oh really? is that a challenge? I'll give you the exported FBX. And I'm sure it'll work in Max too.. hence it working in Lightwave, but I don't need it to work in Max.

[quote]
1. Do you know what different "uv coordinates" exist?


You mean world spaces and units? I'll admit, I'll have to do some testing on that.

2. Do you understand know to set the "FBX" export options!


Depends on the software really. C4D, Lightwave, and PFHoe all have different options for an FBX exporter. Some of them are similar, but others are not. In none of them is there a "switch Y and Z axis or anything like that. Only in Carrara have I seen that option.

To help you understand "UV" Coordinates...
WORLD SPACE
Parent that same object to follow (3) different things with the same animation!
* Box
* Dummy or Point Helper
* Line or Spline
Does any of these objects import into iClone with the correct orientation!


I've done that and I can tell you that the only thing that exports into 3DX are nulls, bones, and geometry. And as far as I know, the nulls do not make it into iClone unless you make them their own subprop.


Camera Data is special!
* Did RL write the importing code to except "Camera Data?" NO!:crazy:

But, RL Did Wrtie How To Handle An Objects "Transforms!:D:D:D


I'm fully aware of that, which is why I parented the camera to actual geometry.

Camera data is not the problem at hand, Sir! It's understanding "UVW" Corrdinates! Sir!

So Now Send That Baby In With The Correct Setting!... Attached to Something Else!;)

It's commom practice to animate a camera using a "Line".... use that Line!:w00t:


Hmmm.. a camera path. If I can export the spline, that might work.

iClone calls this.... Paths..... Oops!;)



Well I still have to get it into a program that opens the project correctly from start... C4D does NOT. Lightwave does... Now I haven't tried HitFilm or After Effects yet, but if I can get a simple camera path from there, that would be great.

I'll have to do some world units testing with both lightwave and C4D and I suppose Max too although I don't use it very often.

Also I can scale things up if it doesn't look right.

I started turning some of the tracking points into polygonal objects to make sure everything stayed in proportion. I'll try some more another time.

NOW... on to your other post.

Hey guys.

I've tried over and over to get camera data into iClone, but it's just stupid.

I can't get the data to export to Lightwave no problem. C4D just fails and doesn't work.

I parent an object to the camera in Lightwave and export as an FBX... but it seems it comes in rotated the wrong way. I try to rotate to what I think is correct but still doesn't work.

Has anyone figured a way to get camera data into iClone??

It'd be REALLY USEFUL if the new 3DX5 supports camear data.
