Object Velocity bug

[Jordan]

Im working with objects travelling forward at speed with flames all over the object and it seems I need to set the object velocities of the deflector geometry and of the object sources from 1.0 to about 0.3 to get proper velocities. Otherwise the velocities seem to push way ahead of the motion.
Anyone else have this issue?

Also on a side note: having no maxscript access to the object properties in fume is very frustrating (Type and SpeedMul). Even multi selecting all the "O" objects in the list greys out all the options as well as the "Use" checkbox.

Hello,

Do you maybe have some clip to show this comparison. In the code, velocities are used just as they are - no extra multiplication is done.

As for MXS try:

obj=$.GetObject( object_index )
showproperties obj

It seems to happen when you have a deflector mesh separate to the emission mesh (emission mesh pushed a bit above the deflector with free flow turned on and object velocities set to 0)

The top green ball is a deflection object with an emission mesh around it with the speed multiplier of the deflector set to 1.0. This has too much forward velocity

The middle magenta ball is a deflection object with an emission mesh around it with the speed multiplier of the deflector set to 0.2. This one is better, but still not perfect.

The lower cyan ball is just an object source with the object velocities set to default (1.0) which seems to sim correctly


Also, thanks for the maxsript. That works (Wasnt obvious in the documentation you could do that)
Is there a way to know what object you are affecting via scripting? would be handy to have a .name or .object with the name string or node referenced in there.

Hello,

Thanks for the file - I will check it to see what's going on with the deflection.
As for the max script, that is added to the wishlist.

Thank you.
