      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.

            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 ๐Ÿ˜„ .

            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.
            ๅฎœใ—ใใŠ้ก˜ใ„ใ—ใพใ™ใ€‚

            Exported from sketchup directly.

            Rendered with Twilight.

            Rendered with Mitsuba.

              Hi,Sminky.

              1. 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
                Spirou4D

                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...

                  Hi,Spirou4D.

                  1---On my computer,preview works fine.
                  So I want you to send me your sketchup file include that problem and tell me the material name of the problem.

                  2---"*" means "Same as SU(Sketchup material)" in my plugin.
                  That error about bumpmap with "same as SU" will happen when the sketchup material does not have texture.
                  So I will change my plugin ignore mapping when sketchup material has no texture.
                  Please wait.

                  And caution-->The texture can be read only PNG and JPG and EXR file in Mitsuba Render.
                  So the error will happen when you use other file format for texture.

                  Thanks.

                    Hi Tak2hata,

                    I have made a copy of my screen and add in my work folder with the SU_render of Mitsuba:
                    https://www.dropbox.com/s/zer0avrjuuqvov0/Essat%20mitsuba%20sketchup.zip

                    But no materials have got a preview! nothing run! and not date!
                    To use Mitsuba, I have place his folder on the desktop because in program file, there are a several problems of permissions issues with SU and Mitsuba. In this way Mitsuba 0.5 work fine.

                    Tell me if you want something... ๐Ÿ˜
                    Thanks a lot!
                    Bye bye

                      I test your file.The material preview works very fine.
                      I could not find the problem.
                      So I modify the script of web dialog by my guess.
                      The path of mitsuba render include any special character?
                      Sketchup ruby can not accept file path include special character.

                      Thanks.

                        Hi Tak2hata,

                        Hum....I think about autorisation because my SketchUp is not installed with an installer .exe but only with copy of folder and Mitsuba too.
                        In french Windows Vista, there are accentuation possible in the path but may be Ruby don't use...?
                        I try your 1.3.4 add-on and see....

                        EDIT 1:
                        This is the path to Mitsuba : [C:/Users/Patrick/Documents/Mitsuba_0.5.0/mtsgui.exe]
                        1 - your release 1.3.4 run well but the "fitSize to SU" button prevents rendering for some texture too little. I have an error message to stop the render with for example: Metal_rusted. With 1000 x 1000 no problem but with fitSize to SU : 0.45 x 0.45 stop!

                        2 - my preview don't run yet but I am sure: it's a problem of autorisation with the .dll or ruby?? no preview texture in the "su_render\preview_cash" folder!

                        Traceback ruby console when I clic on material's preview:
                        Error: #<NoMethodError: undefined method execute_script' for nil:NilClass> C:/Program Files/Google/Google SketchUp 8/Plugins/jbb_layers_panel/rb/states.rb:90:in refreshStatesDialog'

                        onMaterialSetCurrent reusing LuxRender material
                        "call to set_current: Vegetation_Grass_Artificial1"
                        updating swatches
                        setting active material in SU2LUX material editor dropdown
                        "running sendDataFromSketchup for "
                        Vegetation_Grass_Artificial1
                        updating texture fields
                        running load_preview_image function
                        file doesn't exist, showing default image
                        And now when I make a render:
                        file doesn't exist, showing default image
                        Error: #<NoMethodError: undefined method execute_script' for nil:NilClass> C:/Program Files/Google/Google SketchUp 8/Plugins/jbb_layers_panel/rb/states.rb:90:in refreshStatesDialog'

                        EDIT 2:
                        1 I have the solution: in your script the "fitSize to SU" use "," for float and it stop but with "." (dot), no problem! You must change the comma in your script.
                        In french, the numeric keyboard has a dot to float number.
                        2 -
                        "su_render\preview_cash" folder => empty ????
                        "su_render\output" folder => Mitsuba_scene.png ok!
                        "su-render\tx_default" all textures ok!

                        I tried to change "mitsuba.exe" in your script "mod_mitsuba_material.rb" with "mtsgui.exe" to obtain console messages:
                        With the "Metal_rusted" material, I obtain this error of preview:
                        load [fileStream] Error while trying to open file "C:\User\Patrick\Documents\Mitsuba_0.5.0\su_render\preview_cash_Metal_Rusted_.png": the file is not found!
                        because nothing is in the preview_cash!!!
                        and then error with the matpreview2.xml in line 56::
                        <texture type="bitmap" id="45x2-YM255DSL-2.jpg">

                        What is this adress? "C:/freeware/...", in windows it's "C:\freeware..."

                        You can understand now. Where is the mistake?

                          hi

                          you need to disable jbb_layers_panel, first, as it's the first issue...

                          C;/Program Files/Google/Google SketchUp 8/Plugins/jbb_layers_panel/rb/states.rb;90;in `refreshStatesDialog'

                          if this then runs properly, you'll know what the problem is...

                          if not post the next report...

                          john

                          learn from the mistakes of others, you may not live long enough to make them all yourself...

                            Yes Driven,
                            You are right, now in the ruby console I have just this:

                            "All Mesh Stored:0.157000064849854 sec"
                            "OBJ file exported:0.177999973297119 sec"
                            "OBJ&MTL export finished! time is 1.2409999370575 sec"

                            for one render! No other error message but no change about material preview!

                            EDIT 3: Today I have found this file mitsuba.PC-de-Patrick.log in my Mitsuba folder:

                            for the zero aperture, I have corrected but for "sunDirection multiple times" I don't see!

                            EDIT 4: For see in detail the problem, I have load matpreview with mtsgui.exe for obtain the preview and here is the result:
                            Fatal error with this line:
                            <string name="label[0, 0]" value="<!-- preview_material_name -->"/>
                            because the "!" is not read in the "..." like a soft letter but like a command to ruby!!!! Voilร  the problem!

                            EDIT 5: No excuse me I have understand your code: it's not with Mitsuba that file must be loaded but exec by ruby scripts! But no xml file is created by the ruby script in preview_cash!!!

                            EDIT 6: I have placed my Mitsuba folder at the same place like you:
                            C:\freeware\Mitsuba 0.5.0... and try but nothing new below the sun!
                            I can render a scene with Mitsuba but not a material preview!

                            Do you have the same extension.rb and sketchup.rb files like me?

                                Hi Tak2hata,

                                Thanks for your job.
                                In this release 1.3.5, I have this new problem:
                                https://www.dropbox.com/s/1gn2r6h1dww691d/Capture_render1.3.5.PNG
                                When I click the render button in Mitsuba, there are a double line in the progress-bar and I don't see the little bucket-pass jogging on the image! ???

                                    Hi,GreenKot.
                                    I limit the precision of unit for the purpose of smaller file size of mesh.
                                    So I will modify for more higher precision.
                                    And I want to test with your data.
                                    Please send me the skp file.
                                    Thanks

                                      Hi,All.
                                      I uptate this to v1.3.7.
                                      Fix the texture offset problem.
                                      Add Rendering Parameter in export dialog.and set better default values.

                                      The problem of texture offset is not caused by unit precision.
                                      It is texture uv-scaling problem in mitsuba render.
                                      I add uv-offset to exporting texture uv-coords.

                                      Thanks.

                                        Always nothing new: no change with my preview....
                                        But the render run good!

                                          Hi,everyone.
                                          I update this to v1.4.0 in 2014.09.15.
                                          Improve material editor.

                                          Selecting Texture-file was improved.
                                          Material preview maybe run well in any case.

                                          Thanks.
