Just downloaded rc5, and it is looking good for now. Installations works fine and it seems much faster …
I think the materials in the SU plugin are not really working properly with the new material system. Open a scene (*.mxs) you exported from SU in Studio, and look at the materials in the material editor. The parameters are not the same, so that will probably explain emitter problems and uncoloured glass.
Pavol, could you explain how the settings in the plugin relate to those in Studio, and the render engine?

Never heard of Pavol since months ago. Hope he's present.

Pavooool where you are?

well the RC5 outputs new .mxs old .mxs files are not compatible with the studio. You have to regenerate them from the SU scenes ( use file menu, export 3D, and choose MR output, it generates an .mxs file, and launches the render. As soon as render is launched you can cancel it and open the .mxs file in RC5 studio

No one has a clue about the coloring glass issue? Sheik? How does one give color to glass in SU?

Ypnos,

It's an exe so it will install itself. Like messire told you'll must have it under export 3d
Be sure to use the new plugin from the maxwell plugin folder and delete the old one.

I have tested a scene using SU+the plugin compared to exporting to Studio. This has revealed some interesting downsides of the way mxs material settings are assigned to faces in SketchUp.
I created this cube in SU, exported to Silo where I rounded it up by subdivision, then re-imported to SketchUp. The strange cube has 8306 triangles.
The SketchUp file before assigning Maxwell materials is 2,4Mb, and after making it plastic it is 5,5Mb. It takes several minutes for SU to assign the material to all faces.
If I export the file to mxs before assigning Maxwell materials the mxs file is 2,1Mb (default material), and the mxs file with the plastic assigned in SU is 6,7Mb.
Opening the files in Studio explains what the difference is. The file with default materials has two objects (cube and surface) and two materials. The file with the plastic assigned in SketchUp has 8310 materials and objects. The file was importing for about 20 min and then crashed.
Both ways seem to work fine for rendering.
SU+su2mxs with plastic material:

Studio+material assigned in Studio:


If you use studio I recommend exporting to mxs with default materials.

I will test the coloured glass and emitter in Studio….

Ok, some initial findings on the emitter problem:
I created an emitter in SU and looked at the exported MXS file in the material editor of Studio.
It is an emitter, and the settings seem almost correct. I assigned it as D65 and it is using 5000 Kelvin for colour (should be 6500). It looks like the Kelvin setting just doesn’t work in Studio.
I changed the colour setting to Intencity (100 as in SU) and set a colour (it was black after export) and it works.
Select NO for Use Type in the Maxwell Export/ Emitter dialog, and your emitters should work with the colour assigned in SU. 255,255,241 is the colour to use for D65 light.

On the uncoloured glass:
The parameters for the Dielectic material has changed and it uses different parameters now. In fact there is no longer a separate dielectic material. You use BSDF also for transparent objects.
I guess Pavol just hasn’t had time to make the plugin work correctly with the new materials.
Colour doesn’t seem to be exported, and Attenuation distance is set to 999m, which is very transparent (you can see thru a 999m block of the material). Nd, Abbe and roughness are exported correctly.
I think the only way of colouring glass for now is doing it in Studio.

Vodka 79,
What could be the explanation is that there is something wrong with the new settings (or the file) after your changes, and the plugin can’t create the mxs. If the plugin is unable to overwrite the old mxs file, it will still launch the render of the previously written mxs file, if it has the same file name.
Try using a different file name and look for error messages during export.

I had a look at how the plastic material looks in Studio. Plastics created in su2mxs are converted to a material with two BSDF layers (weight 100/100). The other layer has the SU material rbg as reflectance 0 colour and has roughness 100 (Lambertian). The other layer has the reflectance 0 set by the specular rgb colour, and the roughness in set from the roughness U value in su2mxs. Both have white as reflectance 90 colour, which is right for plastics.
This will create a blend of the shiny and rough material, and will produce a look similar to plastic, but not an ideal solution. I don’t think this can be the final solution for how plastics are created from the plugin, and hope it will change in the next version.
I made a test on different ways of created shiny objects, if you are interested (no 1 is how su2mxs exports):

Vodka79,
You probably had an unsupported filetype, or illegal caracters in the map (?).
