Access to UE4_FX Maya Shelf and Export Script

Development Programming & Scripting

How can I get a hold of the UE4_FX Maya Shelf and Export Script used for creating Vector Fields?

2

I was just about to ask the same. Does anyone know where these are now? Is it not included with Rocket Beta?

3

Is there any info on this issue? Does anyone have the Maya shelf script that they can send my way? Is there a way to access it from Unreal?

Hello everyone,
I have prepped the Maya to UE4 velocity grid exporter for release in the next version of Rocket.
In the meantime I have attached the script here in a .zip. Please have a go at it.

Yay!!! Thanks

Thanks a lot!

We’re not distributing it with Rocket for the time being, we’re looking at alternative formats for getting vector fields in to the engine.

Thanks for the info Nick. Even so, it would be fun to try out- even if things will be changing.

Hello Francois!

Just for the tip…
I have some experience with vector fields in Houdini, and I know that any vector can be provided as vertex normal.
So, for example, you can create 3d grid as polygonal mesh.
Adjust it’s vertices normals and export into FBX.

Hope it help…

I noticed the mel script is still not present in beta5, will that change with beta6 or before that? It’s so frustrating not being able to make use of the awesome vector fields :[

11

agreed, this is very frustrating. Epic, please make it available? If not, please tell us how to go about alternative methods for creating vector fields for Unreal- thanks in advance!

Hello guys,
I totally understand your frustration not currently being able to create your own velocity fields. The reason the Maya velocity field export scripts are not included in the Rocket beta is that we are trying to find a more flexible and robust export solution that would work across several DCC apps, so that a wide range of users (indies, professionals) are all able to author velocity fields from their favorite software.
We are working on a solution and will get back to you as soon as we have a progress update.

If it’s any consolation, there are several Vector Fields in the Effects demo.

Did you guys consider adding adding such tools directly inside Cascade Editor ?
APEX Turbulence in UE3 had some tools that allowed for creating effects very similar to those that can be achieved by velocity fields.
It would be cool to get support for such functionality directly inside Cascade.
It would cut entirely the dependence on third party tools, and for most people such solution would be more than enough.

Yes, velocity field authoring in the engine is definitely on the table. It would be a way to avoid roundtripping out of UE4 and also enable support for dynamic velocity grids! (though at added perf cost)

I understand that a universal / in editor solution is preferable, but while working on that, I see no reason why the Maya script can’t be uploaded to the dropbox, as a temporary solution, so that at least the people using Maya get the ability to create vector fields, it’s not perfect but better than the current situation.
