Cool!

First thanks for this great tutorial! Then, a small remind to 4.27 users, don't leave Render Font of the node Draw Text empty. Although it says if it is null, it will use default font, the fact is if you do nothing this node won't work. A lesson took me half day to figure out...

Can you do a tutorial on a snow storm effect and thx for the great tutorial.

[@ozcanozteke284]

I managed to follow you and the effect works on UE 5.1 as well. But I can only call it in the construction script, all other calls won't do anything :/ Would you know why? Thanks!

Hi
Good tutorial, you could make a display text with animation that goes from right to left, a greeting.

[@traviskehler1355]

Does passing a texture into "Set Texture Object" still work for you in 4.26. I can't seem to get the Niagara system to update the sample texture.

[@ArtHiteca]

In version 26, this tutorial did not work, I also tried to check it, but I ran into this problem. this implementation is only relevant for version 25. So far, I can advise you to use a pre-created canvasrendertarget. uasset, not creating it through a function in the bluprint, but only drawing on the one created in the project. In the system, pre-pin the link to this rendertarget . But there will be difficulties in the proportions.

@@ArtHiteca thanks man!

[@justinkim2974]

Firstly, thanks for the tut.
I'm using 4.27 and get a compiler error when adding Sample Texture in the Particle Spawn settings.
"Function call "SampleTexture2D" does not work on CPU sims. - Node: Sample Texture - (insert particle system name), Particle Spawn Script Interpolated."
No idea what this means, and I was just hoping you would have some insight.
Just for context, I'm quite the noob and just started with UE a few weeks ago. Thanks.

Switch to gpu sim

[@justinkim2974]

Hahaha, of course it's that simple. It's always some simple thing :'D. I've managed to render my texture backwards, or in other words, the whole grid spawns, while the image is cut out of the particle grid. Any ideas where I should look to fix this? I've been on it for the last 30 minutes, but that's what is is being a beginner. Thanks again for your help.

An alternative method that that might be useful to someone.
Create a widget and put text or whatever you want in it, attach it to any actor with the widget component, and you can get the texture with the "Get render Target", and the size with "Get desired size" (attached to the "Get widget"), in this way you can also know the size, just wait for 1 frame and check the box in the widget component called "Tick when offscreen", you can put the size to 0 to hide it.
