In the vector field creation guide, it is mentioned that there are many ways to create vector fields for GPU particles. One suggested method I found interesting was the idea of creating a 2D image similar to a normal map to create your vector field.
However, there is no more information about this. Is there a guide, link, or any information elaborating more on this? How do you create a 2D image to be used for a vector field? Is there an example of what one looks like; i.e. is it actually something that looks like a normal map? Is it something you can create in Photoshop, and if so, do you save it as a targa or?..
I’m just a little lost on this and would like to know more, thanks!
so is the only way to create vector fields, with the use of Maya and the custom Epic Games scripts mentioned in the docs- that are not included with Rocket/UE4?
How can I get the Maya scripts that export .FGA files?
I actually used those Maya scripts when I was working on some next gen stuff earlier this year. They worked perfectly for me from Maya2012; I was able to do some amazing GPU particle systems, my art lead loved it.
I was just wondering, is there are specific reason the scripts aren’t being provided to Rocket user? Is that pipeline buggy or has issues? It worked perfect for me when I used it back in May/June. Just wondering, thanks for any info.
