Indigo 0.7F exporter here! Features added/Comments welcome!

[Kram1032]

So, now it works fine: Every single Mesh gets exported, but then:
UnboundLocalError: local variable 'face' referenced before assignment

[afecelis]

@Wedge: now when I set a self ilum material to be applied to a mesh tu make it an emitter my renders show up totally white.

Have the values for creating a self iluminated material changed? How different are they now?

Alvaro

If you have a bezier curve or circle in your scene, you will get the "unreferenced variable: face" error.

Just delete the non-mesh things in your scene before exporting.

[Kram1032]

thx, I'll test it...
I've Just seperated a cubes faces and renewed the centerpoint of them.
But I've Seperated it, until it had 0 faces -> Mesh without verticles^^

[Kram1032]

It works now....

[Wedge]

Great!

I have added a note to the front that says I recommend that you use a mesh uvsphere for .sphere, mesh plane for .plane, and mesh cube [or plane maybe, I did not test?] for .rlight when you use the primitives.

Afecelis, all emitters now use the new light power system. Have you seen the thread for this yet? I remember the thread is in the general section and it was around the end of January.

Thanks for the info zsouthboy.

[afecelis]

thanks wedge, checking it out. So it means it also has to be coded by hand after exporting the basics from blender?

Reading...reading...

The exporter should take care of everything for you.

The only reason you would have to check the xml would be if you needed values that the sliders couldn't give you with the way I set it up. Most of the values are covered....let me see if I can find that thread...

Edit: Found the thread, it is the Indigo 7 test 3 thread in the first post Nick posted a link to a site with many values that can be used for the new light power system. The exporter should cover most all of these values I think.

[afecelis]

Thanks a ton for Wedge! Lots of very useful info. The luminous efficacy link is here:

Hi all,
I've been using Indigo from Blender for the last 2-3 weeks, starting with the 0.6 version, and now I'm testing the 0.7t4 version.
One thing I liked in the v.63beta4 exporter was the ability to launch an Indigo rendering directly from the exporter interface, so I made some "copy and paste" here and there and ended with a result quite functional.
Below you'll find the output of the command "diff" with the changes I made to the original script.
Like on the v.63beta4 you have to set the path to the Indigo directory in the file .blender/scripts/bpydata/IndigoWrapper07.conf.
I tested this script under Windows and Linux, and it works, at least for me..
I hope these additions could be inserted into the "official" script from Wedge.
PS: I'm not an expert in python/blender programming, in fact I'm not an expert programmer at all, so forgive me for any mistake.

GNUdo --> Thanks for the tweak. But...
I guess we have to copy and paste your code somewhere in the script... But where exactly ? At the end ? Or do we have to replace something ?

[afecelis]

I say we let Wedge check it out and update his script on the frontpage

or....GNUdo could upload his version of the script somewhere for us to get it

regards,
Alvaro

[GNUdo]

I guess we have to copy and paste your code somewhere in the script... But where exactly ? At the end ? Or do we have to replace something ?

The code I posted is not exactly what you have to insert into the script, but it contains the differences between the original exporter and the new one.
These changes are indicated with the line numbers where they occur:

Code: Select all

209c209
<       str += "\t\t<name>%s</name>\n\n" %mat.name
---
>       str += "\t\t<name>%s</name>\n" %mat.name

means that the line 209 of the script changes from the first line to the second, and so on..
I'm reluctant to post the entire script, I prefer to have the changes in the first message of this thread, so to avoid confusion.
If you or anyone else want it asap, please send me a private message, I'll wait for Wedge to modify the original before posting my version; if Wegde has definetly left the forum I'll post it in a couple of days..
Ciao

Greetings!

I have not yet seen or downloaded the latest 06 exporter. I thought we would have merged the features of them both by now.

I am waiting I guess to hear from U3dreal because I think he is the author for those features? Or was it someone else? I am not sure if his script is open source. So with that said, I think it is best to keep waiting until he pops in or something.

I realized I assumed Zuegs code from the forum was okay to be added into the open source exporter. (he is one of the authors on the exporter) Even though all credit is in place, I don't want to add code from the forum again until I get the permission directly from the author. I assume by now Zuegs is ok with his fix inside the exporter, but I do not want to make any mistakes.

The code below is the license block into the script: so I think there is no problem in taking some parts of it and using in the v.07 exporter, if you continue to give credits to all the authors.
