Scene Scale

[Otuama]

Hi.

Sorry for not replying sooner.

I've finally gotten round to doing some tests.  Maybe get yourself a coffee 

I created a table cloth scene in both metre & centimetre scales.  I created them from scratch (didn't merge anything into max etc). 

I actually found out something when testing..... if you type, 0.1m into a centimetre scale scene, it actually converts the values   .  I had no idea.

I have included the scenes here, I'd be grateful if someone could have a look:  Max Scenes


------------------

I think I know where I was somewhat going wrong last time, which has led me to more questions and have a feeling there's an underlying issue with the thought that tyFlow can be used in metre and centimetre scene scales without issues.

This is the issue I was having a few days ago.  All I was trying to do is have a cloth twirl with a tyVortex node



It's the Thickness value of the CUDA collision solver.



Even though the scene is set to metres, tyFlow values don't adapt to the scene scale by default.

When I put a value of 0.001m into the box, it sorted that odd issue

However, it still remains the case that all values in tyFlow, even though a scene is in meter scale, the default values are unchanged from the centimetre versions.

-----------------------

Back to the table cloth scene.

I spent a while trying to get this to work.  All values that I changed in one scene I also converted in another.

However, back to the issue above; a lot of values are still using the default ones, but when using metre scane, Max sees the values as being a lot bigger than they should be.

For example:

CUDA collision solver > Self-collisions > Self thickness

Default value = 0.1cm
In meter scale it's 0.1m (10cm)

Here's the results of table test.  Even though I changed values to match/convert in both scene scales, there are still a lot of default values I haven't touched.

METER SCALE
30 Frames = 10 mins



CENTIMETRE SCALE
30 Frames = 34 seconds



-------------------

What would be great is if tyFlow automatically converted default values to adapt to scene scales because it'd be insanity to convert every single value in the scene.

But I can imagine how much of a headache that'd be.

And some default values are 0.05cm, which converts to 0.0005m.  The lowest Max goes down to is 0.001

-----------------------------

I hope at least some of this makes sense.

We need to keep with metre scale scenes so I'm trying to think of a workaround.

I'll bring up the topic of switching to centimetre scale with the office tomorrow.

We did it once but for some reason needed to switch back.

Many thanks!!!
