Can't get the spawning correct #11

Closed enginarer closed 4 years ago

enginarer commented 4 years ago

When I try to create a new VFX graph, it only bursts a single line of particles, instead of covering the whole skeletal mesh and most of the time it bursts only once, even if it's set to constant spawn.

Am I missing something here?

Could you provide the graph that reproduces the issue?

enginarer commented 4 years ago

For this one on the screenshot, I basically duplicated the one (particles.vfx) in your project folder and double clicked it to edit. As soon as I'm in the VFX graph screen, even without changing any node and/or hitting "compile", it suddenly converted into this.

Without editing any of the VFX files that come in your project, it works just fine. As soon as I edit one, or try to create a new one, it ends up like in the screenshot.

I'm on the latest stable version 2019.2.10

Did you set the VFX properties (position map, velocity map, etc.) correctly?

enginarer commented 4 years ago

Yes, I think so. I can send a screenshot of that as well in a few hours when I get back home. But even when I try to edit one of your VFX files, it still does that. So, unless Unity messes with how the properties are set up when I go into the edit screen, I think that has no effect on the issue as well :(

I'll try to recreate the issue on another computer I can find where I am now, so I can see if this is just my PC or a general thing.

This is the duplicate from your Particles.vfx file. Again, it works like a charm after duplicated, but the moment I double-clicked and got to the edit screen to take a screenshot, the spawning breaks down again as well as the constant spawning.

I couldn't find another PC that I could recreate the issue, I will try to find one if I can. I'll share the results here if I do so.

I still can't figure out what's wrong and come up with a solution. It somehow seems to be related with the render textures, Position one initially...

Could you provide this project for me? Please don't hesitate to share it. When trying to solve this kind of setup issues, it's essential to share the same condition.

enginarer commented 4 years ago

Hi, sorry I couldn't follow up for a while. Here's exactly your project, but after me opening the VFX graphs and them becoming "defected". I hope that helps...

Thanks for sharing it. Unfortunately, it doesn't reproduce on my side. They work correctly even after opening them in the VFX Editor.

Not completely related, but I updated the project with Unity 2019.3 (beta). I think it's worth giving a try with 2019.3 because there are several fixes/improvements in HDRP and VFX Graph.

Ah ok, so this is as I feared. I have to find out what's wrong on my system in this case. Thank you so much for your support Keijiro!
