Unity Tutorial: VFX Graph | Texture Sampling

In this Unity Tutorial Matthew Hallberg shows us how to emit particles from a mesh using the point cache bake tool and how to sample colors from the texture applied to that mesh. This was done using the Universal Render Pipeline and does run on Android and iOS. The demo from the intro was utilizing this effect in augmented reality with Vuforia's cylinder tracking.

Fantastic tutorial!. Short and to the point with great explanation. 🤯

What if i want to set each particle position to where it is red only?

Thanks so much for your tutorial but I can`t add texture within the sample texture 2D. Does anyone else had this problem?

[ElenaInspiringWorld]

Particles don't appear when i import the vfx graph into the scene (ref: 2:12 min in the video). Tried everything but no particles show. Thanks for your help :)

hey there, thanks for the great video! I love the effect!
However with the same setup i receive an unhealthy amount of shader warnings. The partilce effect seems to work though... I assume it's because of combining URP and shadergraph. Do you have any tips about that?

I'm diving into vfx graph myself. Super awesome once you get to grips with it, think the initial learning curve is weird.. you can use code over the graph a lot as well

Hey, Thanks. That was really helpful. Any chance you know how to deal with orienting the particles using the normals of the mesh?

How to add trail to these texture sampled particles?

is there a video on how to export this for the iPhone?

Hey, thank you for the tutorial! Maybe you know how to solve the following problem: I am trying to convert an image to a point cloud and for this a baked a texture to the pCache. But when I use it in VFX Graph as a position map, it generates a square result, even though my texture is not square. Do you happen to know this problem and the solution?

Great! Anyone found out how to do Texture Sampling with static meshes(NOT cache baked meshes)?

So my man, where did we land on the whole, machine learning, on android, also interactions with hand tracking. I have something working but getting the tracked hands to interact with the AR objects gets a bit tricky for a python dev. Preciate it!

After changing the shader to universal render pipeline the whole cube becomes pink
