Yes you can, you just add another position and do “min” node on that. I explain it in this video Scaling Cubes VFX Unity Visual Graph - part 2 ruclips.net/video/AxYMx4-zSJ8/видео.html at 13.15 👍🙂

Happy to hear! Oh, I can't give an easy answer. I need to dive into that. Actually, it’s a good tutorial to cover. But I would recommend isolating the issue with just a box in a simple system. Figure out how to solve the position based on the system, and then apply it to the positions. You need to fiddle with the World/Local space in the VFX. You can tick on the VFX system in the top right corner. Also, use the position node to get the system's position and use add or subtract with the player’s position and particle position to transfer from world to local positions to solve it. Not a straight answer, but a pointer in the direction you need to go. I will try to remember to post here when I have a tutorial covering that. Good luck!🙂

Oh its really hard to say like this, but is there a node that gives you error? if you hover your mouse over it and middle-mouse click. What do you get any error guidance that explain in any way? what time stamp in the video do you get error?

That make me happy to hear! Thanks 😀. You motivate me

It should work on everything. Did you change your texture to normal in inspector for that texture? Also make sure you keep it in the boundaries, scale it down before export in Houdini and then scale up in unity.

@@TechHamlin Thanks ! It's solved. Everything look correct after I reduce scale value, so limiting bound size is the key?

@@黄海光-l4w Yea I think it is because vertex color is clamped to 0-1 value. And if you are animate something that exceed distance longer than can be saved in vertex channel then that's when the problem occurs. Probably more ways to sole it. But that is how I Solved it. I would like to be able to skip scale it in Unity. If someone solve that or now something please share. Happy you solved it :-)

Looking for the part 2!☺

I’m glad you liked it, then you should check out this one too. Procedural Blood Splash Shader Graph Unity ruclips.net/video/sbudpV1zrqg/видео.html it do cover some more stuff

Glad you think so!

Im glad you like it! I just verified its the correct link. You are looking for the project on github right? Then this is the correct link. github.com/NikLever/Unity-URP-Cookbook

Sorry, been thinking about it but that will not happen as for now. Though unreal is mutch more complete and powerful. Been using Niagara when I worked on a AAA game. It’s really good. Hope unity add features they have. One for instance is mixing GPU and cpu in same graph is really useful and spline support is so much better… but I decided unity is my shit. There is a lot of good tuts though, you should find 🙂☀️

Hmmm, you might not have the right solver, or you are in the "wrong" folder. What I mean by that is if it is the same folder/node as in the tutorial? Maybe you ended up in the wrong place? Then the context cant add pop wrangle

@@TechHamlin Hey thanks for the quick reply! Someone pointed out I am not using the FX license but a core license, that made the difference :)

@@annakohler977 oh! can be many reasons 🙂

What I do know is this guy, but he stopped doing stuff. But really good stuff, learned a lot my self there. www.youtube.com/@IndiePixel3D This guy I know to! www.youtube.com/@brundlethwaite

@@TechHamlin Thank you

Hehe oh yeah

VAT! It runs on GPU

Hehe feels good that I’m not alone then 😁

Hmm, you mean you can’t find the node? In that case just write custom, and see if you find it. Also I don’t know if you need to have experimental features ticked in settings. Try that out 🙂

@@TechHamlin Wow, ticking the experimental features did it .. thank you so much sir 🌹 , also I have another nooby question, my mesh particles do not cast shadows .. is there any setting that can be disabling it?

@@mostafa3beed118 Glad it worked! That might be you need to choose "lit" shader. Also, check you light if shadows is set to on/off. Could also be a setting inside the shader. check the graph settings

@@TechHamlin It was a check box in the scriptable object related to the lit mesh block and it worked .. thank you so much 🌹

Thanks! 🙂 Yes than should be pretty straight forward. Are you using Unity or Unreal with Houdini Engine?

@@TechHamlin I faced the issue inUnity so I worried about my setup then I tried to test in UE.

@@ominhtriet6163 It should work with no problems. Make sure that your @Cd is a vector and not something else like float. and save it on points in Houdini. And that should be enough to work. So for instance I had a problem in this tutorial in the end where occlusion was saved as f@Cd and not v@Cd. ok? Just do a box, and then a point wrangler with v@Cd = @P; and wrap it up like a digital asset. That should work

@@TechHamlin you are right, It should work when @Cd on Point but I wanna inject the Vertex Color to shader. I also used the Houdini Starter Kit from Sidefx, they use Point Attribute to control Color, I tried to get that infromation to Shader but failed.

Then it should just be a vertex color node in Shader graph?! Have you controlled you have the correct material assigned? Other than that I can’t think of anything else

Try to break it down on smaller things to solve. One step at the time. Maybe doing this tutorial first so you understand the basics! Then you will solve it 🙂

I know, its great! A friend made it, Pär Davidsson www.unitedsound.se/ is the one who made the music!

@@TechHamlin Will it be on Spotify?

@@mewko3906 The music guy said he would put it there. I will ping you when that happens. Or if he publish it somewhere else 🙂

Hehe

So Happy to hear 🙂 thanks!

Glad you feel so :-)

Ohhh good thing you reminded me! 😁

Its all about how plugins are made. I don't know how it works under the hood, but I suspect its like this. A vertex can be offset buy 1 unity. imagine you have a boundingbox around each vertex. It can only offset 1 unity or maybe 0.5 unity in each direction because vertex map is between 0-1. (each pixel in the texture only does vector3 from 0 - 1). so buy scale it down you can actually offset it 10 units., thus the boundingbox is 10 units. This is nothing I have confirmed anywhere but that's how I suspect it works. Its all about bounding boxes and how plugins are made. I have different experience in Unreal 5 with Houdini for instance.

Oh!! thanks a lot for sharing, I'm definitely gonna check that out.

oh man I though they only use Houdini with UE hahah, you guys still here

Its HDRP. But it should work the same way in URP. Just make a Shader Graph UPR and it should work just fine 🙂

@@TechHamlin where can I get the shader and the graph

​@@harshadakhandelwal3459Sorry for not being clear, it's not available anywhere. You need to follow the tutorial. Good luck!

Hello my friend! What exactly do you mean with abc cache? In this texture you bake everything into a VAT texture. what exactly are you looking for?

@@TechHamlin This part I mainly used to deal with the interaction of the hull with the sea and the interaction of the creatures with the sea surface, the generation of abc is the way the movie and television workflow, I use the vat process with Houdini output found that there will be a limit to the number of vertices, I do not know how to apply the vat process correctly!

ah alembic! Its soooo contex based on how easy/hard it is do solve that. if your abc file have the points number (ptnum) not jumping around but following the animation if you understand what I mean, then it should be not to hard. But break it down to smaller problems and solve it one by one. I guess your first step would be to read the attributes and understand how attributes get affected by animations inside Houdini. Then take it from there. Hope I point you in right direction 🙂

@@TechHamlin Thank you for your reply, I understand for the time being, to go through the vat process, there is a limit on the number of model faces (about 200,000 or so), if more than these faces try to deal with it in chunks, and there is also a change in the number of points in the abc file as you said, I'll test test test again!

You default settings do export color data. That is vertex color. Make sure you save it as @Cd as attributes on the models. This is for models. However if you want to export point cache, then don't use fbx, use the method described in the tutorial

@@TechHamlin Thank you, I have resaved the vertex colors in Blender and now successfully exported the point cache.

@@PoohWinnie789 Happy you solved it! 🙂

A nice you solved it, can be a bit fiddling :-)

It is! But I’m not using triplanar to do this mesh, it’s 3d noise only 🙂

@@TechHamlin Oh my bad I thought there was some kind of projection going on for wrapping it, that's what I get for skimming the video

It was very fun to make 🙂

Its very useful! Here you are 🙂 drive.google.com/file/d/1WM0Upa5DsyekA5_eLfslMp71xCTbvnLK/view?usp=drive_link

Thats because you bounds in Iniialize Particle section is outside your camera view. Change the Size and that will sort it out. When Camera View don't "see" the effects center it will stop render to save performance :-)

It is! I should do more tuts about it. Its so fun 🙂

In a way yes. Sounds like a fun thing to investigate. I might do something about it, thanks for idea 🙂💡

@@TechHamlin Glad you found it fun, looking forward to the video...

Actually Im thinking of making a new one like v2. because the noise only gives out 1 float you get a stretched noise if you noticed. Put different noises for each x & y. Make sure you offset input position for one of the noises and you get even better shader! 🙂

@@TechHamlin Thanks to you I was able to make a cool blood effect for the game, but there is one thing vfx effect has bad collision. I think I'll just do it with particle system

Yea its hard to know the problem :-).But are you running it in edit mode or playmode? If you do edit mode, then make sure you have [ExecuteInEditmode] in the script. Also, try to narrow the problem down, so if you have avoid values, crank up all the values to see if it even affect at all. And if it do affect, maybe you can narrow it down to the parameters that's not working for you. Maybe need to tweek some amp values or so to make them move away stronger?

@@TechHamlinI dont want to ask too much but is it possible for you to give the project file ? So people that got problème like me can compare and see where we fail Maybe ? I would love to compare the unityproject to see where I fail and learn from this !

@@TechHamlin i find the solution it was because i didnt reset the transform of my vfx (it's always small details like this in unity or ue ahah)

Im glad you solved it! And thats the best thing when you solve it your self. Actually Ive been thinking about a patreon site, where I post the scenes for all tutorials. As example you asked for it. Do you think it would be a good idea? @@takeomasaki3423

@@TechHamlin It could be a great idea i know that i cannot afford a patreon but maybe sum people can and it would be great! (it's always better than nothing)
