MCG Path Constraint a.k.a IncrCloneOnCurve

Date Updated:

This MCG constraints your object motion to a path. The motion can be repeated forever beyond the curve.

It can also be used to incrementally clone object along a curve and there is no need to adjust the distance

between the clones and count when length of curve changes.

 

Ver 1.01.00: You can now use a curve to control scaling of the clones.

Ver 1.02.00: updated due to SP2 catering for multi curves in a spline. However this will still work only on the 1st curve in a spline. I have not updated multicurves functionality yet.

I strongly advise you to get SP2 as this provides a great speed boost to MCG....and extra stuff, of course.

ver 1.04.00: now supports multi curves in a single spline. Also added Rotation control curve for Cloning, and Fake movement to utilise Scale/Rotation curves in PathConstraint mode.

Ver 1.05: added Pivot Gap option...WARNING: becareful with low gap values....ie. there will be shitloads of clones for gap approaching 0, I've actually put minimum at 1 for safety reasons.

Ver 1.06: updated for Max 2017 to fix Spline/Path related flaw (please continue to use 1.05 for Max2016)

Ver 2.00: This version will work for both 2016 and 2017. Please note for 2017, you'll get deprecated messages, it's OK, it will still compile and run.

Ver 2.01: you can now rotate your path freely

test scene - same issue no

test scene - same issue
no clones
I can see only 2 boxes in one spot, increasing number makes no sense

win10 ?

what about win10, I'm on win7, I hear win10 is not officially supported (for max2016 that is) yet.

Also, my mcg install is local ie. on my c:\blah blah....yours is not on some network location I assume (still, I don't really see a problem there tho)

Hmm...

Hmm... I have Nitrous enabled so I'm not sure what causes the slowdown. I'm also not running any other processes or documents in parallel with Max.

I will test it on a couple of other PC with Max and will let you know the results.

seems OK

after various tests, I'm getting about 150-200FPS, the odd occasions I see 70FPS.

Then I pushed the clones up to 100, did some more tests and still getting about 150FPS.

My system has a 4770K, 16Gb ram so it's less than yours...but this file is tiny so I think machine spec is not the problem. Dunno what it is...your machine was not stressed out by other processes right ?

Update:
What about graphics driver? I use Nitrous and was getting 150-200FPS,
I switched to default legacy direct3D and I got about 10FPS !!!

is it possible for you to send the Max file ?

only then I would have a better idea...

I did a simple test with teapots, way more 'complicated' than a box and I get ~200FPS..lowest was about 60FPS and my machine is less powerful than yours...

Problem with MCG

Very useful, thanks. I just installed the MCG (version 1.01.00) to try it out and it works but unfortunately it is really slow for me. When I start adjusting any parameter of the MCG modifier, the viewport updates very slowly and FPS drops dramatically (~5-10 FPS). I tried it with a box which is not a heavy object. My PC is i7 4930k, GTX 980 4GB, 32 GB RAM. Do you know what might be the cause?

Thanks in advance!

added GetCurveLength compound

I've converted the Get Curve Length logic into a compound so ppl can use it more easily...does not require EXT1.
