[bazuka]

that's nice but im getting this error

// Error: float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist .z); //
// Error: Syntax error //

[MattTheMan]

ok i fixed it. same script. just edited and fixed.

[bazuka]

...i'll try...

tryed, and sorry to say but script doest work at all :(

[MattTheMan]

funny... it works for me and a few other testers...????

Are you using Maya for Mac or something?

[Synthesizer]

Hmm, I get the same thing:

// Error: float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist .z);
//
// Error: Line 74.67: Syntax error //

I'm using Maya 7.0 on a PC. An older version that you posted on the indigo forum works for me though.

[bazuka]

ok i know how to fix that error, but i dont how to fix other problems when u export scene and try to render with Indigo...

// Error: float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist .z);

make sure that there is no space at the end of the z*$dist .z);
-> float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist.z);

[bazuka]

ok this post will be looong :) (simple scene, camera and one poly sphere)

had to attach it :)

this is what i got from maya:

----------------------------------------------------------------

and when i try to render scene i get these errors:

SceneLoaderExcep: could not find root 'scene' element
Fatal Error: SceneLoaderExcep: could not find root 'scene' element

ok when i fix that error coz indigo doesnt understand maya string
(<!--Exported from Maya--!>) just remove it...

then im getting this error:

Using Reinhard tone mapping with pre_scale=2.000000, post_scale=1.000000
SceneLoaderExcep: TinyXmlWrapper: could not find element 'lens_radius' in elemen
t 'camera' (around line 36)
Fatal Error: SceneLoaderExcep: TinyXmlWrapper: could not find element 'lens_radi
us' in element 'camera' (around line 36)

ok when i fix that error im getting next one:

Using Reinhard tone mapping with pre_scale=2.000000, post_scale=1.000000
SceneLoaderExcep: TinyXmlWrapper: could not find element 'angle_of_view' in elem
ent 'camera' (around line 36)
Fatal Error: SceneLoaderExcep: TinyXmlWrapper: could not find element 'angle_of_
view' in element 'camera' (around line 36)

so i didnt have time to play more, so it's very nice to have this script, but plz people fix it to work...

[Elvis75k]

same here.. and // Error: No object matches name: camera1_up.tx //

Anyone has a working version? In the Flipcode forum i found this one
http://www.flipcode.dxbug.com/board.php?topic=417
but still buggy or it's just me?

-e

[bazuka]

u'r getting that error coz u didnt make camera, aim and up!

:)

[Elvis75k]

u'r getting that error coz u didnt make camera, aim and up!

:)

i did.. lol

[MattTheMan]

Ok, sorry for the trouble, guys.

Camera-aim-up: don't rename it.

Also, I forgot to say- Triangulate mesh, then delete ALL history before running this script. Else, Indigo will not find the correct materials. I will have the script to do this (well, probably not delete history, but the triangulation part).

Also, this script WONT WORK with indigo 0.4. That's why it won't find Lens Radius, and angle of view.

If you go to the indigo forum, you can find Indigo 0.5test6. Use that one.

Ok- I think this script should work better-

Try it out. Also, tell me all of the bugs, it does help me make it better. And I am adding support for meshlights now.

Thanks, and I will do my best to fix what I can.

Again, use with Indigo 0.5.6, 0.5.5, 0.5.4, or 0.5.3. Get them at the Indigo forum.

[bazuka]

no my friend script doesnt work

Using Reinhard tone mapping with pre_scale=2.000000, post_scale=1.000000
SceneLoaderExcep: TinyXmlWrapper: could not find element 'lens_radius' in elemen
t 'camera' (around line 35)
Fatal Error: SceneLoaderExcep: TinyXmlWrapper: could not find element 'lens_radi
us' in element 'camera' (around line 35)

[MattTheMan]

Ok, sorry for the trouble, guys.
Also, this script WONT WORK with indigo 0.4. That's why it won't find Lens Radius, and angle of view.


;)

Link to Indigo 0.5.6-

http://www.flipcode.dxbug.com/board.php?topic=485

And if Indigo 0.5.6 won't start, add this to your ini file "max_num_consec_rejections" "100"

Knock yourself out

-Matt

[victor]

I've got the 0.5.6 version, and it works with the test scenes.

But I can't get the script in Maya to work. Getting...

// Error: float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist .z); //
// Error: Syntax error //

Yes, I made a camera, aim, and up. Yes, I deleted history and triangulated.

[bazuka]

victor my friend u didnt read the posts before, problem is in the space before that dot

// Error: float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist .z); //

float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist.z);

got it? :) (u cant see here, dont know why board makes this space)

[MattTheMan]

Yeah, I just went back and edited the post and rewrote that line, and now the space doesnt show.

So, it works now? :)

I'm adding meshlight support now.

-Matt

[bazuka]

should work, but im still getting error for:

Fatal Error: SceneLoaderExcep: TinyXmlWrapper: could not find element 'lens_radius' in element 'camera' (around line 35)

[bazuka]

i dont get it Matt, whats the problem, cant u write one more line in mel for lens radius???

[victor]

Works for me now.

Bazuka, are you sure you are rendering the right scene?

The test scenes that come with the earlier version are missing some lines in the camera section.

To get it to work, I unzipped the 0.4 version, and then on top of that the 0.5.6 version. Then added the "max_num_consec_rejections" "100" line to the INI file.

Now, I'm just rendering from the command line...

indigo.exe test.xml

Good start! :)

Edit: It's been a while since I got to try Maxwell, and I'm obviously using just simple scenes with this now, but is it just me or is this actually faster than Maxwell?

[MattTheMan]

Well, looking at samples from Maxwell and my own test scene, it might be that Indigo 0.5.6, especially with Complex IOR materials is faster then Maxwell 1.0. cool, eh?

I coded in meshlights. To enable a meshlight, all you do is you turn up the incandescense value of a material- and that object ceases being an object- and becomes a meshligt ;)

Also, I am gonna start attatching it as a txt file or something, this code thing is still ripping apart that $FD value- $dist. z.

so, when you copy and paste- look for float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist. z);

and replace it with

float $FD = sqrt($dist.x*$dist.x+$dist.y*$dist.y+$dist.z*$dist.z);


EDIT- here it goes again, ripping apart my code :( take away the spaces from the end of $dist.z

Please test, as always.

Oh, and no I can't add lens radius and angle of view, because 0.5.6 won't read it then.
Just do what victor said.

-Matt

[bazuka]

found it, :)

[MattTheMan]

so it works now?

anyway, I'm adding specular materials and sun support now.
-Matt

[bazuka]

yeah, but :) it's slooooooow, mean render....

[MattTheMan]

And so is Maxwell :p

[bazuka]

yeah, but i dont use maxwell :)

[MattTheMan]

ok, here's an update. You can choose wether to use Skylight, Physical Sky, and none.

If you do choose Physical Sky, you need to create a point light, dont rename it, and position it where the sun is (taking the target as 0 0 0).

Same $dist. z problem, but you can fix that yourself ;)

-Matt

[wedge]

i was able to get a successful render from Maya to Indigo, but with a small discrepancy.

on the right is an indigo render after 2 minutes of rendering. on the left is the viewport. the object is well within the camera boundaries, but when rendered i only get the bottom half. strange, no?

the odd shadow is not an error - the object was accidentally off the ground.

rendered with physical sky.

[MattTheMan]

Yeah, well that's the difference between Maya camera and Indigo camera. Just zoom out a bit, shouldn't be too much of a problem. I'm sorry, I'll look into any way to fix that.

In the meanwhile, I'm trying to convert this script to c++ and make a Maya Plugin, since MEL is toooo sloooow. It actually crashed my Maya yesterday... trying to export 50,000 polys

-Matt ;)

[wedge]

okay, that's probably why it crashed maya when I tried to export the Jotero ajax bust.


but, hey, at least it works, right?

I had the same problem, it's the way the camera is setted up. Just like Matt said zoom out a bit.

Btw, Matt it's blitzmaya. :thumbsup:

[MattTheMan]

hey people, long time no update :D

arneoog (from simply maya or indigo forum) and I have been working together since the last update- trying to bring some flexibility into this script. Now with an actual UI!

however, I have not tied most of the UI into the actual core YET- but the basics work. (skylight, background light, and the bidirectional setting :p)

anyway- it's a zip file as of now. images go to your maya->6 or 7-> prefs->icons/ folder.

please read the readme file first... it will tell you what to do, since there are 2 mel files.

edit/ in the UI- go to lights- and click the sun icon for the sunposition (that's right, no more point light) and also you can create a camera through the UI too /edit

[bazuka]

nice man, i have only one objection u must make indigo to support HT...

[MattTheMan]

oh, that's not me, I don't make Indigo, just the maya plugin :D

but I think HT DOES speed up the render significantly.
