Gérald, I downloaded and played a little with the Aline dress product (static sim only, so far) -- Here are my thoughts:

PROS:

• It feels like VWD (though, heavily crippled)
• Collision object import settings available
• Draping works fine (same as VWD complete product)
• Wind works fine (same as VWD complete)
• All the "live" sim settings work (Gravity, Inertia, etc. -- same as VWD complete)
• No issues with Start/Stop static sim for multiple re-sims per single session with Send To Host multiple times for morph target work (same as VWD complete)
• No issues with live deformation sim (though, only allowed on skirt)
• The view settings work with the cloth (color, wires, opacity -- same as VWD complete)
• Standard selections work (via shortcut keys only [shortcut key selection only NOT A PRO])
• Vertex locking/unlocking works (via shortcut keys only)

CONS:

• Auto-selection of cloth object (no user input)
• All import settings automatically set (no user input)
• Top half of cloth object locked to collision object with no way for user changes (no user input)
• No in-use parameter settings available (no user input/changes allowed)
• No view setting changes for collision object (color, wires, opacity)
• No select-by-material
• No custom selections
• No live deformation usage with top of cloth object (locked to collision object)
• No cloth shrink available for cloth object (collar strap/breast straps in desperate need of it)
• If not for already knowing the shortcuts -- No visual way to indicate to NEW users a way to lock/unlock vertices from simulation, nor how to engage selections

Now, these are more just based on personal taste of an experienced, advanced technical user, but I tried to put my mindset that of a newbie purchasing the product and having a play -- Just pushing buttons and see what happens (I know I cheated - I already knew the expected results).

I see what you are trying to do with this, but I think there are a few shortcomings for ease of use for newbies just purchasing for a quick sim with the cloth object.

• Pick collision object -- Check
• What to do next? -- Not sure (no indication cloth object is automatically selected/imported - just no more options) -- Press the Scene Viewer header to go to full screen of VWD -- No, just collision object in scene -- Press the Scene Viewer header again to go back to docked view.
• Eventually press the Simulate header -- Ahhh... that's it -- The cloth auto-imported and simulation auto-started.

I would put the cloth object auto-selected/imported and simulation auto-start in the PRO category, but it was too much of a guessing game just to get started, and I am a seasoned veteran -- Imagine a newbie purchasing not knowing what to do. You need to make the workflow very clear from the start.

Maybe, change it from having to press the Simulate header to an actual Cloth button like the Collision button (which auto-engages the Simulate header, go full-screen, and starts the sim as you have it)

Other than a not so clear start up, it is fine, but personally, I don't like it as a product. I believe the tool should not be included in the cloth product, and you should find another way to implement your auto-simple/non-pro quick sim clothing product to work with the already purchased tool.

Imagine you have 10 different cloth objects for sale and I purchase all 10 -- Now, I have 9 extra versions of the same crippled VWD to dispose of...

I like your idea for those who don't want/need full control, and just want a quick sim, but I think it should fall on the tool purchase side, and not the clothing side.

So, You already have the full VWD (let's call Pro), and a non-animation VWD version (let's call Standard). Maybe you should create a third VWD (this version in the cloth product), and call it something like Hobbyist or Quick Sim version. And, you can decide to make it free/available only for those who purchase a clothing product for it's use.
