Hi
I've bought your pack for Unity and try to recreate VFX with UnrealEngine. But I have a problem with shaders -shader code is generated and hard to read. As I understand you use Amplify Shader Editor for creating shaders. But i recevie "Missing shader functions" errors when I try to open you material with Amplify Shader Editor . Could you please help me with it?

Hello, can you double check that “Particle Shaders” folder and all the files inside of it was imported in your project.
Unfortunately I didn’t build these shaders myself. A friend built these shaders for me. I actually know very little about making shaders.
If you’re unable to get it working in amplify, then I’m more than happy to give you a refund since it didn’t serve your needs.
Please let me know how things turn out.
Hi
I checked it again yesterday with updated version of the asset pack. There are missing shader functions
Is it possible for you to ask your friend about this functions? Maybe he can provide them to you?
About refund - I bought this pack few mounths ago and only week ago started to use it trying to recreate effect I need in UE. If your friend can't provide to you missing shader functions and it is ok for you to give me a refund after 3 month it would be great. If not - so anyway it is my fault, I had to check it earlier :)
