Cool Rendering image.

Very nice ones!
Any ideas of the rendering time for one image?

driven

this one is a 13.3 MB skp file, the others took less time each. information stamped exr are saved on render...

OK, got the plugin working, sort of . The ui I get when runinning mitsuba do0es not allow for changing mats/textures etc, is there a ui I am missing or is there a simple explanation I am missing? I get that I do not have the full picture and having found the readme file in the mitsuba directory am kicking myself for my earlier question ans the answer is there. What am I missing?

What I see.

@mike

the materials editor is part of this plugin, load it through the SCF download tool and it open mitsuba after you use it.

Hi,john.
This script roundup the matrix values.
42 line of code in mitsuba_main.rb
Please Delete that line.
The error will not appear.
Now I still can not return to home.
So I can not edit this script for a month.
Please modify it yourself.
Thanks.

I am not sure this is related to this exporter plugin but allow me to ask it:
I tried rendering an animation with mitsuba and all worked fine apart that I got the frames in .exr format that is not supported by virtualdub so I can't make a movie of it;
how to change the output format of animation frames?
Sorry for my noobness, best regards and thanks in advance.

Sorry, I forgot to say I am on windows 8.1.
Also, I could use an app to concert single exr images to jpg but when I have hundreds of frames, it becomes impossible to do it manually.
Sorry if I miss something about that app or anything else, as I said before I am still a newbie.
Thanks

P.S.:It would be great if you could make mitsuba render animation of objects done with Proper Animation plugin or other similar tools.

Hi,Sminky and All.
I update this to version1.3.2 in 2014.04.26.
Add Selector image format in export dialog.
and Improve material editor.
and bug fix about transformation for very small.

Enjoy!

First of all, thank you very much TAK2HATA for your precious work. I am liking Mitsuba-san more and more.

I am going to propose you some things, I don't know if they are of simple implementation or not .

1)I said it in my previous post already, sorry for repeating: rendering of objects animation made in sketchup using proper-animation plugin or similars.

2)Implementing a non-raytracing rendering algorithm similar to Houdini software or similar to compare the results with different techniques.

3)Rendering texture transparencies properly (maybe it's already possible but I couldn't do it) as explained in the following pictures. The first one is just exported directly from sketchup and you can see that the fence texture is shown with transparent parts but the shadows are like if it was a non-transparent texture; the second is rendered with Twilight and you see it has transparent parts in the texture and the shadow is properly calculated as if made by just the black parts of the texture; the third one is made with Mitsuba-san and it has no transparent parts both in the texture and in the shadow.

Thanks in advance for your time and patience.
宜しくお願いします。

Exported from sketchup directly.

Rendered with Twilight.

Rendered with Mitsuba.

Hi,Sminky.

I did not use proper animation ,yet.
So I consider it in future version.

2)It must need new exporter.It becomes too gigantic work.So I can not do it.

3)Please use mask option in material editor of my exporter.
Or I will consider automatically enabling the mask option in future.

Thanks!

Material preview:

I have Windows Vista 32bits carte Nvidia GT 630 4 go ram OpenGL Cuda core
Processor biquad 2.6 gHz

SketchUp r8.0.14346 (run very well)
Mitsuba 0.5 (run very well)

and your addon release 1.3.2

When I want material preview, notihng change! just a terminal window during few minute and close.
1 - But the thumnail don't change, I have always the "CLICK HERE UPDATE" message.

2 - when i choose for a bump map, "Same as SU" with the "*" in the left case, and i want to export my scene, Mitsuba stop with a message "Error while creating object: (null)"
but without a bummpmap there is no problem!!!

Congratulations for your great work, Mitsuba is a very good GI render engine!
Bye bye

PS: I have saw on the video: In your material windows, there is the date and at home, I have a "?" ! May be it's the problem...
