Another attempt to add individual moving people.

I also think that I am slowly getting to the technical limits of the simulation and animation possibilities in SketchUp and that such ventures could well be continued with Blender, Unity or Unreal. That's why I like to watch how savvy SketchUp users show these ways. Thanks Chipp!

Improvement of the effect of the wind from the copter rotors on the leaves and branches.
And improved the particle simulation to reduce the storage volume and rendering effort for the many surfaces.
The raindrops, splashes and water marks appear only in the field of view of the camera depending on speed and direction of movement.

The future of Venezia...
please tell us something more about the process: rendering, postpro.. .

Thank you all for your "wow".
Fixed camera and only a few moving objects are the best for quick GIF output.
Modeling, animation and rendering for the short final full HD NPR film need a bit more time...

Two exemplary frames of NPR video sequences - day and night simulation - and a GIF snippet of the pure rendering.
The MSPhysics model and the NPR film are still in work. I want to see a few moving branches and relaxed walking people...
Used: MSPhysics, indigo RT, FotoSketcher, VirtualDub, Shotcut and a few models from 3D-Warehouse

Here is the reduced code to export scenes in one go as single images with transparent background. This is not a plugin.
Important: Disable Scene Transition, name scenes properly, switch off sky and floor in the SketchUp style used, include the scenes to be exported in the animation
Copy the code to the Ruby console and press Enter
The images end up in the directory where the model is stored.
Sources for code snippets: the above mentioned free plugins from Thomas Thomassen (thomthom) and Rick Wilson

model = Sketchup.active_model
pages = model.pages
original_page = pages.selected_page
model.start_operation "ExportScenes"
	path = (model.path.sub(/.skp/," - "))
	pages.each do |page|
		if page.name==page.label
			pname = path+(page.name.to_s)+".png"
			Sketchup.set_status_text("Writing #{pname}")
			pages.selected_page = page
			options = {
			      ;filename     => pname,
			      ;width        => 1920,
			      ;height       => 1080,
			      ;antialias    => true,
			      ;compression  => 0.9,
			      ;transparent  => true
			 }
	    		 model.active_view.write_image(options)
		end  
	end
	pages.selected_page = original_page
model.abort_operation

Unfortunately, the exporter does not work for my purpose, the export of hidden line stiles on a completely transparent viewport. For this I would have to be able to make a Color (White)transparent before exporting. But luckily there are video editing programs that can be used to overlay animations in different styles.

Yeah, that's what I thought. Spontaneous customization of existing plugins for your own purposes may go too far. Maybe I should only post the changed or used code snippets to disclose and discuss the interventions. Maybe oceanembers can make something out of it for himself.

Since I thought I could also realize my own wish - animations as line style representations with transparent background to overlay them with rendered animations - I combined 2 plugins.
Thomthom's tt_export.rbz and Rick Wilson's sceneExporter.rb have been turned into a scene exporter that outputs all animated scenes as one 2D PNG files with transparent background (tested under SketchUp 2016 Pro and 2017 Make).
Since I don't know if I'm violating copyright, I wanted to ask if I can post the modified plugin here?

The easiest drawing exercise imaginable in SketchUp obviously doesn't work anymore since some versions (as I see, fortunately not only for me) - dividing flat and textured surfaces with drawn straight lines.
Another problem when drawing lines on textured surfaces is that SketchUp often creates multiple coplanar faces and also deletes adjacent textures. It's quite a fiddle editing this tangle. Usually it works better not to draw the lines, but to copy adjacent longer lines to the desired place and to delete protruding parts.
Plugins such as 2D Tools (TIG), Edge Tools (Thomthom) or Fredo Tools (Fredo6) are also helpful when drawing or editing lines on flat surfaces.

After grouping, rotating I used the same plugin - then reverse faces, transfer textures, move back and turn, explode..

Have often the same problem.
I use tt_flatten.rb (thomthom).
You'll get a new group and then have to revert faces, draw lines to generate faces and bring the textures back... (5 min)

Have found a solution for my problems rendering ivy instances with indigo/indigoRT.
The reason is, Indigo cannot place this instances correctly if the last element in the transformation matrix is not equal to 1.0.
The code replaces leave component instances generatet with the "LiveIvy" plugin with there definition.
The trick is to position the definition at exactly the same place with the same transformations like the original instance but with a scale factor of 1.0.
The code is a modification of "scale_reinit" by Matt666 under use of "Scale Reset", "Reset Scale Rotation" by sdmitch and code lines of "Scale Definition" by TIG.
It's use is the same like scale_reinit. With selected instances you find Replace_CI_Definition in the context menu.
If someone uses indigo to render LiveIvy models, he can test it with the model in a previous post.
But don't worry - after using the plugin the model looks exactly the same as before..

Replace_CI_Definition.rb

Oh, I don't think I've explained my problem clearly enough. I have to work on the translation. I meant the permanent storage of manipulations to subgroups in replay files. These are lost after closing the model file and later opening and loading the replay data.

Hi Anton,
A question for functions of a next version of MSPhysics:
Could it be possible to store transformations (translation, rotation, scaling) and manipulations off visibility on nested groups in the replay record data?
At present, these changes can be retained during an MSP session, played back and exported as a movie (frames), but disappear after saving, closing and reloading the replay data.
Here is an example of manipulating the visibility of embedded groups to achieve the effect of winking, if you want to test it.
Thanks!

The same here. All of my posts are gone..

Congratulations - fantastic light, beautiful furniture and plants, excellent renderings...

Is there a plugin that resets the scaling of several components selected at the same time? The native SketchUp function for a bunch of "extremely" scaled ivy leaves, for example. If you reset the scaling of the ivy leaves, the render program (e.g. Indigo) can calculate the positions correctly. However, resetting the scaling individually for thousands of sheets is very laborious.

If that's what I think, I'm glad I only tasted it, but I didn't step on it...
