Exploring Unreal Engine 5 Niagara Simulation Stages and Grid2D Collection

This is a rambling exploration on how to use Niagara's Grid2D collection in Unreal Engine 5 and show how to create grids, write into grids, what the indexing scheme is and how to write the data into a render target in a material.
This is a much better video on the subject from Andreas Glad....

Thank you for this - I've found it to be challenging getting started on these subjects - this video has helped a ton!

[@jazznezzz]

Thank you for taking time to make this video! Super helpful and especially considering niagara documentation is always lacking.

[@ryankosame5309]

Thanks so much for the more detailed explanation for this, Now I knew the logic behind!

[@quackcharge]

thanks a lot, super helpful

[@majorsmashbox5294]

Great video, very informative and honestly feel you went into more detail than Andreas explaining the Sim Stages.

[@ooorc46]

very detailed!!! Thank you, man!

[@FXology]

Awesome tutorial, learnt many things from one video)) I'm very curious about exporting generated data from Niagara to Blueprint, for example Render Target 2D. Is there any ways to take this data and operate it in BP?

Could you make tut how bake niagara 2d simulation into flowmap texture?

Thank you a THOUSAND TIMES. The perfect follow up to Andreas' videos. Just ignore these ungrateful b****** down there

I've been trying to write to a rendertarget within Niagara for a while now, without any luck getting it to actually effect any externally created Render Target 2D.
I think it stems from not being able to set the Render Target User Parameter value in the emitter spawn stage (the dropdown does nothing). I can however bind the entire RT object to the user parameter instead, but this hasn't seem to let me write to it. Do you have any idea why this might be the case, or how I could correct it?

[@kokiriswordsman1742]

Solved, I was assigning a rendertarget2D rather than a TextureRenderTarget

Please chose a different camera angle! not very flattering

[@AsdPiton_veloby]

Extremly slow. Nice ideas that could be told in 5-10 minutes. but the content itself is good.

An hour of whispering. Nah.
